8 THE WITNESS: I do.

 

 

9 DIRECT (Kenneth Rutchey)

 

 

10 BY MR. KOBELINSKI:

 

 

11 Q. Good morning, Mr. Rutchey. My name is

 

 

12 Mark Kobelinski. Have you been deposed before?

 

 

13 A. Yes.

 

 

14 Q. You have, all right. Good. I think I

 

 

15 knew that.

 

 

16 And I think you're aware that a deposition

 

 

17 is a means by which people involved in litigation can

 

 

18 ask questions of individuals who may or may not have

 

 

19 facts dealing with the issues in the case under oath.

 

 

20 I'll be asking you a number of questions. I believe

 

 

21 one or another of the attorneys here will be asking you

 

 

22 some questions. I'd like you to answer to the best of

 

 

23 your ability as truthfully as possible. If you don't

 

 

24 understand a question, please let me know and I'll

 

 

25 attempt to rephrase it in a manner in which you can

6

 

 

1 understand. If you don't know the answer to a question

 

 

2 or don't remember, I don't know or I don't remember are

 

 

3 the best responses you can give.

 

 

4 If you do assume something, please let us

 

 

5 know. Otherwise we're going to go on our own

 

 

6 assumption that you are not assuming. If you feel

 

 

7 compelled to assume, please tell us.

 

 

8 Under those ground rules, you were served,

 

 

9 sir, I believe with a subpoena duces tecum?

 

 

10 A. Right.

 

 

11 Q. All right.

 

 

12 You were given a notice and, as I

 

 

13 understand it, you've gathered documents in response to

 

 

14 that?

 

 

15 A. Yes.

 

 

16 Q. You produced those all to us?

 

 

17 A. No.

 

 

18 Q. All right.

 

 

19 A. This morning I brought in, after reading

 

 

20 it further, a report. You might have this, you might

 

 

21 not. I don't think that was -- the C-51 study, you

 

 

22 said all publications that I've been involved in.

 

 

23 Q. Okay.

 

 

24 A. And this is another one that was by Dewey

 

 

25 Worth in the early '80's, work that he did in

7

 

 

1 documenting the vegetation, and I have basically all

 

 

2 the data for that report since Dewey has now left the

 

 

3 District.

 

 

4 Q. Great, all right.

 

 

5 Well, we'll get some copies of that later.

 

 

6 A. And the other item I was asked to provide

 

 

7 was the digital data also.

 

 

8 Q. Um-hum.

 

 

9 A. The techs and I haven't put that all

 

 

10 together yet.

 

 

11 Q. All right.

 

 

12 A. I'm working on that.

 

 

13 Q. Now I note that you have a document there

 

 

14 in front of you, titled Development of an Everglades

 

 

15 Vegetation Map Using a SPOT Image and the Global

 

 

16 Positioning System. Is that the final or most recent

 

 

17 copy of that particular paper?

 

 

18 A. Yes.

 

 

19 Q. All right.

 

 

20 And I know you did produce that; is that

 

 

21 correct?

 

 

22 A. Yes.

 

 

23 Q. All right.

 

 

24 Well, why don't you give me few moments to

 

 

25 go through it. We weren't quite sure which was the

8

 

 

1 final version.

 

 

2 (Thereupon, a discussion was held off the

 

 

3 record.)

 

 

4 MR. KOBELINSKI: All right. We all set?

 

 

5 Why don't you mark that as 1?

 

 

6 (Thereupon, the document was marked

 

 

7 Rutchey Exb. No. 1 for Identification.)

 

 

8 BY MR. KOBELINSKI:

 

 

9 Q. Mr. Rutchey, I've handed you what we've

 

 

10 marked as Petitioner's Exhibit 1 to your deposition,

 

 

11 which is a document entitled Development of an

 

 

12 Everglades Vegetation Map Using a SPOT Image and the

 

 

13 Global Positioning System, dated September of 1992,

 

 

14 Bates No. 1220147 through 1220440. Would you look

 

 

15 through that and identify that for me, please, if you

 

 

16 can?

 

 

17 A. This is the work that Les Vilchek and I

 

 

18 did, looking at vegetation in the Everglades and using

 

 

19 multispectral satellite data to delineate the

 

 

20 vegetation.

 

 

21 Q. Okay.

 

 

22 And what portion of Everglades was that?

 

 

23 A. Water Conservation Area 2A.

 

 

24 Q. Okay.

 

 

25 When was this work done? When did you

9

 

 

1 start on this project?

 

 

2 A. I'd say initially right after the data was

 

 

3 acquired on 8-10-91.

 

 

4 Q. Okay.

 

 

5 And when did you finish this project?

 

 

6 A. I'd say approximately eight months after

 

 

7 the actual -- all the data was collected and then maybe

 

 

8 another four months the final report was done.

 

 

9 Q. So that was just about September '92 is

 

 

10 when you finished up with this?

 

 

11 A. Yeah, I'd say that was the last, you know,

 

 

12 the revised. You know, you get comments back and...

 

 

13 Q. What we've marked Exhibit 1 is the final

 

 

14 product from that study, or are there any additional or

 

 

15 subsequent drafts?

 

 

16 A. There was drafts prior to this, yes.

 

 

17 Q. Were there any drafts subsequent to, after

 

 

18 this?

 

 

19 A. No.

 

 

20 Q. Okay.

 

 

21 Who is Les Vilchek?

 

 

22 A. He's a co-worker, same level as I am,

 

 

23 working for South Florida Water Management.

 

 

24 Q. What does he do?

 

 

25 A. He's -- he does pretty much what I do. He

10

 

 

1 has a strong background in aerial photography

 

 

2 delineation, dealing with aerial photography. He

 

 

3 worked with the National Wetland Inventory before he

 

 

4 came to the District and basically learned the image

 

 

5 processing from me, the digital image processing and we

 

 

6 used his background in aerial interpretation pretty

 

 

7 extensively in this project.

 

 

8 Q. Thank you.

 

 

9 Prior to August of '91, did you have any

 

 

10 experience in using satellite imagery, showing

 

 

11 vegetation through satellite imagery?

 

 

12 A. Yes.

 

 

13 Q. Could you just briefly take me through

 

 

14 when you first started doing that actually through

 

 

15 today, what your experience has been?

 

 

16 A. Okay.

 

 

17 I'd say I started, I would say it was in

 

 

18 '87 when I first became interested in this method. I

 

 

19 basically had done a lot of research in the Everglades

 

 

20 prior to that using standard ground reconnaissance, you

 

 

21 know, going out in the field as a biologist and looking

 

 

22 at vegetation, put a transect out. Basically that's --

 

 

23 the results of that are in contained in this report

 

 

24 that Dewey Worth did. But we saw there was so much

 

 

25 more out there that we weren't covering, so we wanted

11

 

 

1 to move on to maybe looking at the area in its

 

 

2 entirety. And then initially we started just taking

 

 

3 photographs from helicopters, putting poles out in the

 

 

4 fields so we can basically tell distances, so that when

 

 

5 we delineate the vegetation we can come up with an

 

 

6 acreage of what things were that we were delineating

 

 

7 were or so -- were on the ground.

 

 

8 And so we then basically moved to

 

 

9 satellite data and Dewey, you have to give Dewey the

 

 

10 credit. He's the one that really headed us in that

 

 

11 direction. I just sort of, I guess, tagged along. But

 

 

12 it piqued my interest and I became very interested in

 

 

13 it. In fact, it became my niche at the District. And

 

 

14 at that time we had the I2S system, which is an image

 

 

15 processing system and I learned it and I did some

 

 

16 initial work. And basically at this point I was

 

 

17 getting a real education at the District learning the

 

 

18 software and different techniques and...

 

 

19 Q. Put an approximate period of time around

 

 

20 this.

 

 

21 A. I'd say '87 to '89.

 

 

22 Q. Okay.

 

 

23 A. I did a preliminary map of Water

 

 

24 Conservation Area 2A using a 1987 SPOT scene. And then

 

 

25 I started working on this -- this project, completed

12

 

 

1 this work. At this point I'm moving more now towards

 

 

2 using satellite imagery and aerial photography. I

 

 

3 consider all remotely sensed data or image processing

 

 

4 of data. That's it pretty well.

 

 

5 Q. Okay.

 

 

6 A. Sums it up.

 

 

7 Q. You say a 1987 SPOT vegetative map, was

 

 

8 that -- what area was that?

 

 

9 A. Water Conservation Area 2A.

 

 

10 Q. With regard to the photo surveys using

 

 

11 helicopters for use in vegetative mapping, what period

 

 

12 of time was that?

 

 

13 A. (No response.)

 

 

14 Q. I believe you said you used, did some

 

 

15 photo surveys using helicopters where you put posts in

 

 

16 or poles in to mark --

 

 

17 A. That was before any actual digital image

 

 

18 processing. That was real early like, I'd say, in the

 

 

19 '81 through '85.

 

 

20 Q. Okay.

 

 

21 Do you recall what areas you did using

 

 

22 that method?

 

 

23 A. Basically it was sawgrass areas, tree

 

 

24 islands and slough areas.

 

 

25 Q. Okay.

13

 

 

1 Was that in any of the Conservation Areas?

 

 

2 A. Water Conservation Area 2A.

 

 

3 Q. Did you cover the entire Conservation

 

 

4 Area?

 

 

5 A. No.

 

 

6 Q. Do you still have the results of those

 

 

7 surveillances or not?

 

 

8 A. Some of it.

 

 

9 Q. Did you publish a report or put out any

 

 

10 type of report based on that?

 

 

11 A. Basically all that work is probably in

 

 

12 here.

 

 

13 Q. Okay.

 

 

14 A. We collected a lot of data and we put this

 

 

15 report together. We didn't use all the data. We used,

 

 

16 you know, we collected a lot of data, so it was...

 

 

17 Q. Okay.

 

 

18 Going then towards this report which we

 

 

19 marked as Exhibit 1, if you could walk me through the

 

 

20 process.

 

 

21 And I believe, just for the record, the

 

 

22 copy that has been marked as Exhibit 1, I do not

 

 

23 believe has color photos on the back of it. I know

 

 

24 that you have another copy of that here -- is that a

 

 

25 fact, Mr. Rutchey --

14

 

 

1 A. Correct.

 

 

2 Q. -- of this report which does have color

 

 

3 photos?

 

 

4 A. (Shakes head up and down.)

 

 

5 Q. Feel free if, during the deposition you

 

 

6 need to refer to color photos as opposed to those black

 

 

7 and white photocopies to do so. We will then attach a

 

 

8 corrected one with the color photos to the deposition

 

 

9 itself.

 

 

10 If you could literally, from the point

 

 

11 where you became involved, walk me through the steps it

 

 

12 took to get to this final report, and if I need a

 

 

13 little more detail I'll ask you. Otherwise --

 

 

14 A. Okay.

 

 

15 Q. When did you -- I assume the first part of

 

 

16 that was selecting a -- well, you tell me. Step Number

 

 

17 1, when did you get the assignment?

 

 

18 A. Well, we got the imagery that was

 

 

19 collected on August 10, 1991 from SPOT data

 

 

20 multispectral imagery.

 

 

21 Initially the first thing we do is went

 

 

22 out and got ground truth information to rectify the

 

 

23 imagery.

 

 

24 Q. Before you get to that point, how was the

 

 

25 August SPOT imagery selected?

15

 

 

1 A. Basically the overriding consideration was

 

 

2 availability. In the Everglades we don't have a lot of

 

 

3 clear days where we have a satellite where it's totally

 

 

4 cloud free.

 

 

5 Q. Um-hum.

 

 

6 A. So that was why that one was selected.

 

 

7 Q. Okay.

 

 

8 Who actually made the selection of the

 

 

9 August 10, '91 SPOT imagery?

 

 

10 A. I did.

 

 

11 Q. Okay.

 

 

12 And was this -- was SPOT imagery the only

 

 

13 satellite imagery that you considered at this point?

 

 

14 A. No, no. We looked at LandSat too. Again

 

 

15 the overriding consideration though was a scene that

 

 

16 was totally cloud free for that area.

 

 

17 Q. Okay.

 

 

18 A. And there was some other work done using

 

 

19 LandSat in the Everglades, and they compared it to

 

 

20 SPOT, and they showed that SPOT was the better way of

 

 

21 looking at the vegetation and delineating.

 

 

22 Q. Okay.

 

 

23 Who had done this LandSat work and

 

 

24 compared it to SPOT?

 

 

25 A. Terry Gilbert of Game and Fish.

16

 

 

1 Q. Did you consult with Gilbert with regard

 

 

2 to selecting the SPOT imagery?

 

 

3 A. Yes.

 

 

4 Q. Had you worked with the LandSat before?

 

 

5 A. Yes.

 

 

6 Q. And did you concur with Mr. Gilbert's

 

 

7 opinion that SPOT would be a better imagery to use as

 

 

8 opposed to LandSat?

 

 

9 A. Yes.

 

 

10 Q. Okay.

 

 

11 What was the specific purpose or goal at

 

 

12 this point in time of the assignment? What were you

 

 

13 attempting to do?

 

 

14 A. Use satellite imagery to delineate the

 

 

15 vegetation in Water Conservation Area 2A.

 

 

16 Q. Any particular vegetation types or

 

 

17 literally all the vegetation you could?

 

 

18 A. All the vegetation we possibly could.

 

 

19 There was no emphasis on any specific species.

 

 

20 Q. Okay.

 

 

21 And did you select 2A as the area of study

 

 

22 or was that just, again, part of the assignment?

 

 

23 A. Selected it. Because that's where I had

 

 

24 worked since my beginning of employment with South

 

 

25 Florida Water Management District, and that area also

17

 

 

1 has had the most work done in it in previous.

 

 

2 Q. Okay.

 

 

3 Was the assignment literally just to map

 

 

4 any area within the Water Conservation Areas, open area

 

 

5 selection? How was the assignment developed?

 

 

6 A. Basically just we mapped Water

 

 

7 Conservation Area 2A.

 

 

8 Q. I'm just curious whether or not the

 

 

9 assignment was we need to start doing a vegetative

 

 

10 mapping, and you said fine, I'd like to do 2A because

 

 

11 that's what I'm most familiar with. How was that

 

 

12 assignment developed?

 

 

13 A. I would say that the direction at that

 

 

14 point came from Dewey Worth to start off doing Water

 

 

15 Conservation Area 2A.

 

 

16 Q. Okay. All right.

 

 

17 Did you review various SPOT imagery for 2A

 

 

18 and then select August 10 from a number of options or

 

 

19 was August 10 essentially the one that was proposed to

 

 

20 you?

 

 

21 A. Again, there wasn't a whole lot available

 

 

22 due to cloud cover. And it's -- I didn't want to go

 

 

23 back to a scene that was collected earlier because then

 

 

24 it makes it hard to ground truth. So I had to wait for

 

 

25 a scene to become available and then start working on

18

 

 

1 it.

 

 

2 Q. Okay. All right.

 

 

3 In what format did you receive the August

 

 

4 10 SPOT imagery data?

 

 

5 A. In digital format.

 

 

6 Q. Did you still have those digital files?

 

 

7 A. Yes.

 

 

8 Q. Unaltered, unmodified?

 

 

9 A. Yes.

 

 

10 Q. Okay.

 

 

11 Once you received the digital files for

 

 

12 the '80 -- excuse me -- 8-10-91 SPOT imagery, what did

 

 

13 you do next?

 

 

14 A. I went out, collected ground truth data

 

 

15 for rectification of the imagery. We collected 20

 

 

16 ground control points. That was the first thing we

 

 

17 did. Then we cut the actual area out that we were

 

 

18 interested in, which was Water Conservation Area 2A,

 

 

19 out of the imagery.

 

 

20 Q. Okay.

 

 

21 So let me -- first, after getting the

 

 

22 data, I assume you load it on to a computer, then went

 

 

23 up to selected 20 sites to ground truth --

 

 

24 A. To ground truth for rectification

 

 

25 purposes.

19

 

 

1 Q. And what does ground truthing for

 

 

2 rectification purposes mean?

 

 

3 A. When you get the data it's not to any real

 

 

4 world map projection. So we wanted to get it into a

 

 

5 real world map projection using real world ground truth

 

 

6 information.

 

 

7 Q. Now in other words, when you get it, it

 

 

8 doesn't have the boundary of 2A drawn on it; is that

 

 

9 right? Is that --

 

 

10 A. No. The way you get a boundary is to cut

 

 

11 the imagery from the satellite, original satellite

 

 

12 data. This rectification is so that when you look at

 

 

13 an area and -- you know where the location is at.

 

 

14 Q. Okay.

 

 

15 A. You don't know that when you first get it.

 

 

16 You have to establish ground controls and rectify it.

 

 

17 Q. So what are the types of sites you use for

 

 

18 that purpose?

 

 

19 A. Some of the fish camps within the area and

 

 

20 then points all the way around the outside perimeter.

 

 

21 Q. That including the structures?

 

 

22 A. I believe so.

 

 

23 Q. And did you do the 20 sites, inspection of

 

 

24 the 20 sites for ground truthing?

 

 

25 A. Les Vilchek and myself.

20

 

 

1 Q. Approximately how long did that take?

 

 

2 A. I would say a day to two days to collect

 

 

3 the information.

 

 

4 Q. Okay.

 

 

5 What's the next step?

 

 

6 A. Okay.

 

 

7 Initially we took the raw data and did an

 

 

8 unsupervised classification and we chose 30 clusters.

 

 

9 We did the unsupervised classification within the 30

 

 

10 clusters. We tried to find areas that we can visit in

 

 

11 the field. And this was all based on the accuracy of

 

 

12 the GPS. So basically the imagery was initially

 

 

13 rectified to .4 RMS, root means square, it means that

 

 

14 pixel within it is accurate to approximately eight

 

 

15 meters.

 

 

16 Q. With regard to this process, how many

 

 

17 classes did you -- did the computer or did you collect?

 

 

18 A. 30 clusters.

 

 

19 Q. 30 clusters, all right.

 

 

20 Let me ask you this, perhaps as we go

 

 

21 through, for the sake of -- we received a fair number

 

 

22 of documents, a lot of which are, as you know, lists of

 

 

23 data. With regard to Step 1, which was selecting the

 

 

24 August 10, 91 imagery, did you produce any documents

 

 

25 specifically related to that fact?

21

 

 

1 I'm just trying to organize the documents

 

 

2 that you produced.

 

 

3 A. Could you repeat that question?

 

 

4 Q. You've produced to us about a foot and a

 

 

5 half of documents in the last few days.

 

 

6 A. Okay.

 

 

7 Q. We're trying to order them to understand

 

 

8 exactly what they are and identify them. Perhaps it

 

 

9 might be easiest to see which of those documents fit in

 

 

10 a particular project you were doing and in what steps.

 

 

11 I'm asking you, did you produce any documents with

 

 

12 regard to your selection of the August 10, 91 SPOT

 

 

13 imagery?

 

 

14 A. Yes.

 

 

15 Q. Okay.

 

 

16 What documents would have you produced in

 

 

17 regard to that?

 

 

18 A. If I remember, all -- I think you have all

 

 

19 the GPS location points that were used in the

 

 

20 rectification process, in the ground truthing and in

 

 

21 the your analysis of the mapping project.

 

 

22 Q. Okay.

 

 

23 I understand we probably have all the

 

 

24 documents. Our problem is trying to figure out which

 

 

25 documents are for what task. Are there specific

22

 

 

1 documents with relation to your selection of the August

 

 

2 10, '91 SPOT imagery?

 

 

3 A. I don't think so.

 

 

4 Q. With regard to your selecting 20 sites for

 

 

5 ground truthing and for rectification purposes, were

 

 

6 there any documents specifically related to that task

 

 

7 that you've produced to us?

 

 

8 A. I believe so.

 

 

9 Q. What would those look like?

 

 

10 A. Well, I identify them based on the folder

 

 

11 that I have them in.

 

 

12 Q. Well, we received those things clipped or

 

 

13 rubber banded together. There's the first batch,

 

 

14 perhaps if you went through that and can identify the

 

 

15 20 sites or the documents related to the 20 sites for

 

 

16 ground truthing.

 

 

17 While you're doing that, let me ask a

 

 

18 quick question. Are you aware that we received your

 

 

19 documents in two batches?

 

 

20 A. No.

 

 

21 Q. Okay.

 

 

22 So that wouldn't help, telling you I

 

 

23 received it in Batch 1 or Batch 2.

 

 

24 (Thereupon, a discussion was held off the

 

 

25 record.)

23

 

 

1 BY MR. KOBELINSKI:

 

 

2 Q. It's not there. Okay. This is another

 

 

3 set of documents we received.

 

 

4 A. I don't see them.

 

 

5 Q. Okay. At the break we can take a closer

 

 

6 look at that.

 

 

7 Moving on to the next step that you

 

 

8 described to me as taking the raw data and looking at

 

 

9 the computer, doing an unsupervised classification,

 

 

10 would there be any specific documents generated from

 

 

11 that? Would the computer generate a particular file

 

 

12 or --

 

 

13 A. I believe all it's all digital. I don't

 

 

14 think there's any hard copy of that.

 

 

15 Q. Okay.

 

 

16 Now, do I understand correctly that the

 

 

17 computer collected more than 30 classifications, but

 

 

18 ultimately narrowed it down to 30?

 

 

19 A. No.

 

 

20 Q. How does that work?

 

 

21 A. I chose 30.

 

 

22 Q. Oh, you essentially told the computer I

 

 

23 want 30 classifications, go through and find them?

 

 

24 A. I want 30 clusters to be my final number

 

 

25 of classes.

24

 

 

1 Q. Okay. Well, you have to excuse me, I'm --

 

 

2 the difficulty is you have someone who is not expert in

 

 

3 your field deposing an expert in your field.

 

 

4 When it's an unsupervised classification

 

 

5 by the computer, does that mean the computer just goes

 

 

6 through and selects what it considers to be vegetation

 

 

7 of the same class or cluster?

 

 

8 A. Basically it looks at the band information

 

 

9 of the satellite data and clusters it out based on

 

 

10 means, basically it's a standard deviation, into 30

 

 

11 separate clusters.

 

 

12 Q. But you're the one that first plugs in to

 

 

13 the computer and tells it I want 30 to start with?

 

 

14 A. Right.

 

 

15 Q. So you could have done 40 and it would

 

 

16 have given you 40?

 

 

17 A. That's correct.

 

 

18 Q. Or you could have given it one and it

 

 

19 could have -- would have given you the entire map I

 

 

20 guess; is that essentially correct?

 

 

21 A. Yes, I think that's probably what would

 

 

22 happen.

 

 

23 Q. Did you write any memos or anything

 

 

24 related to that particular document?

 

 

25 A. Not to my knowledge.

25

 

 

1 Q. Okay.

 

 

2 After you received then the computer

 

 

3 classification of 30 clusters -- would that be the

 

 

4 appropriate term?

 

 

5 A. Yes.

 

 

6 Q. Okay. 30 clusters.

 

 

7 -- what was the next step you did?

 

 

8 A. Okay.

 

 

9 Basically, we tried to go out in the field

 

 

10 and identify what those clusters were.

 

 

11 Q. Okay.

 

 

12 How did you go about doing that?

 

 

13 A. We used GPS, Global Positioning System,

 

 

14 and tried to pick a minimum of five points in each one

 

 

15 of these clusters, geographically locate it throughout

 

 

16 the area. And that's what we used for trying to

 

 

17 determine those 30 clusters.

 

 

18 Q. Okay.

 

 

19 Just so I understand how you went about

 

 

20 determining the 30 clusters, did you print out a map?

 

 

21 Was there a map printed out of it showing the 30

 

 

22 clusters, where they were?

 

 

23 A. That's correct.

 

 

24 Q. All right.

 

 

25 Do you still have a copy of that map?

26

 

 

1 A. It's digital.

 

 

2 Q. All right.

 

 

3 Did you allow the computer to select the

 

 

4 sites where you would go out and ground truth or

 

 

5 determine what clusters represented or did you do it

 

 

6 yourself?

 

 

7 A. Did it myself.

 

 

8 Q. Okay.

 

 

9 Do you have any type of map or -- showing

 

 

10 where those sites were that you visited for the

 

 

11 determination of classes?

 

 

12 A. Yes. I -- there might be a hard copy, I

 

 

13 can't remember. But there's definitely a digital copy.

 

 

14 Q. Okay.

 

 

15 And in the digital copy, would it have the

 

 

16 coordinates of where you were going?

 

 

17 A. That's correct.

 

 

18 Q. Okay.

 

 

19 How did you go about selecting sites you'd

 

 

20 visit?

 

 

21 A. It was based on whether we were able to

 

 

22 accurately navigate to them use GPS technology. There

 

 

23 was some inaccuracy in the actual GPS and some

 

 

24 inaccuracy in the rectification process of the

 

 

25 satellite imagery. So basically we determined that we

27

 

 

1 had to have a minimum of 3 by 3 pixel cluster in order

 

 

2 to accurately navigate to. In most cases we prefer to

 

 

3 have bigger than that.

 

 

4 Q. Now with a 3 by 3, you're talking about,

 

 

5 what is that, 60 meters squared?

 

 

6 A. 60 meters on side. 60 by 60 by 60 by 60.

 

 

7 Q. All right.

 

 

8 And how many sites did you go to identify

 

 

9 the clusters?

 

 

10 A. 129.

 

 

11 Q. All right.

 

 

12 And that was yourself who picked the 129

 

 

13 sites?

 

 

14 A. I would say I picked them along with Les

 

 

15 Vilchek.

 

 

16 Q. Okay. All right.

 

 

17 What was the next step then, visiting the

 

 

18 sites?

 

 

19 A. We visited the sites and we wrote down

 

 

20 what we saw there and came back and wanted to see if

 

 

21 the cluster was accurate and it -- it had broken it out

 

 

22 into 30 clusters, whether they were all unique. And at

 

 

23 this point we determined they weren't unique, that

 

 

24 there was real heterogeneity with a number of clusters.

 

 

25 Q. Now prior to the visitation to the site,

28

 

 

1 how did you get to the site?

 

 

2 A. Either by air boat or helicopter.

 

 

3 Q. Okay.

 

 

4 And you did that using GPS, I believe you

 

 

5 mentioned?

 

 

6 A. That's correct.

 

 

7 Q. Okay.

 

 

8 Once you got to the site, I believe you

 

 

9 stated you identified the vegetation?

 

 

10 A. That's correct.

 

 

11 Q. What would you do, check a site in the

 

 

12 center of the pixel, in the center of the 9 square or 9

 

 

13 pixels?

 

 

14 A. Approximately.

 

 

15 Q. Then how would you go about identifying

 

 

16 what was there?

 

 

17 Who would do that? Let's start with that.

 

 

18 A. We stuck with one person so that we

 

 

19 wouldn't -- it's just better if you do it with one

 

 

20 person than have a number of people working on that

 

 

21 aspect of it, because he stays consistent throughout

 

 

22 the process.

 

 

23 Q. Okay.

 

 

24 A. And Les Vilchek was that person.

 

 

25 Q. Okay. All right.

29

 

 

1 Once you arrived at a site, where would he

 

 

2 look to make the identification?

 

 

3 A. If we were in a helicopter he would look

 

 

4 down at the site, because you want to try to determine

 

 

5 what the satellite was seeing. If you were on an air

 

 

6 boat, we have cages on the air boat, we got on top of

 

 

7 the cage and looked basically down so we can see was it

 

 

8 sparse or moderate or dense or what the prevailing

 

 

9 vegetation signature was for that area.

 

 

10 Q. Okay.

 

 

11 With regard to the helicopter, were you

 

 

12 hovering, trying to hover at any particular level or...

 

 

13 A. Yeah, I'd say it was approximately 50

 

 

14 feet.

 

 

15 Q. Okay.

 

 

16 A. 25 feet.

 

 

17 Q. All right.

 

 

18 You now -- as I understand it, you are in

 

 

19 the approximate, what you've identified as being in the

 

 

20 approximate center of a 9 pixel square, each pixel

 

 

21 being 20 meters by 20 meters. Was Les attempting to

 

 

22 identify the community in all 9 pixels or was he trying

 

 

23 to look at what he considered to be the boundary of

 

 

24 that center pixel?

 

 

25 A. I would say he was looking at a 20 meter

30

 

 

1 by 20 meter area.

 

 

2 Q. Was that something you discussed with him

 

 

3 so you know that or is that just your --

 

 

4 A. No, we discussed that.

 

 

5 Q. Okay.

 

 

6 Now at -- during this trip would you also

 

 

7 observe and take any notes if, for instance, if there's

 

 

8 a change in the type of vegetation surrounding -- from

 

 

9 what you've identified as the center pixel?

 

 

10 A. I believe he did that, yes.

 

 

11 Q. Now were there written documents? Were

 

 

12 there written observations from this trip?

 

 

13 A. I believe there is, yeah. I think he --

 

 

14 they might be included here somewhere.

 

 

15 Q. But he made field notes of every, all 129

 

 

16 visits?

 

 

17 A. I believe so, yeah.

 

 

18 Q. Okay.

 

 

19 Was he keeping the field notes or were

 

 

20 you?

 

 

21 A. He kept them pretty much.

 

 

22 Q. Okay.

 

 

23 Did you make any separate observations or

 

 

24 field notes of any sort?

 

 

25 A. No. I was basically the GPS man. I

31

 

 

1 also -- I put it in in navigating to points and making

 

 

2 sure we got to the right place.

 

 

3 Q. Okay.

 

 

4 Now, is it your belief that the field

 

 

5 notes from these site visits were included in the

 

 

6 documents that were produced to us?

 

 

7 A. I think so, but I'm not positive.

 

 

8 Q. Okay.

 

 

9 Can we go through and again identify those

 

 

10 so we can start segmenting out what these documents

 

 

11 are? If it's easier, as I said, take all the rubber

 

 

12 bands off.

 

 

13 (Thereupon, a discussion was held off the

 

 

14 record.)

 

 

15 THE WITNESS: This is in digital form. I

 

 

16 don't see the --

 

 

17 BY MR. KOBELINSKI:

 

 

18 Q. Let's set that aside for the moment.

 

 

19 Everything that's -- everything you have that relates

 

 

20 to the -- is it just that one document you have in your

 

 

21 hand or is there anything underneath that also?

 

 

22 A. Well, this actually gives you the

 

 

23 coordinate and what we saw there. I'll keep looking

 

 

24 through.

 

 

25 Q. Well, I'd like to see if we do have field

32

 

 

1 notes. Let's -- why don't we set that aside. I'll

 

 

2 identify that for the record in a moment. But if

 

 

3 there's anything else related to that visit to the 129

 

 

4 sites in the field and the identification of

 

 

5 vegetation.

 

 

6 A. I think this pertains to that too. I

 

 

7 think these are it. We actually made sheets up, field

 

 

8 inspection sheets. I think this is it.

 

 

9 Q. All right. Let me try find these here.

 

 

10 MR. CESERANO: You want the number?

 

 

11 MR. KOBELINSKI: Yes.

 

 

12 MR. CESARANO: 1202944.

 

 

13 THE WITNESS: No, this, I think, was for

 

 

14 ground truthing.

 

 

15 BY MR. KOBELINSKI:

 

 

16 Q. Why don't we put -- this is yours, and I

 

 

17 think you turned some stuff over here. I just want to

 

 

18 make sure.

 

 

19 MR. CESARANO: Pardon me, let me look at

 

 

20 this for a moment if I could.

 

 

21 MR. KOBELINSKI: All right. What does

 

 

22 that start with?

 

 

23 MR. CESARANO: 1203.

 

 

24 MR. KOBELINSKI: All right. And I think

 

 

25 we'll just mark this as a large composite

33

 

 

1 exhibit.

 

 

2 (Thereupon, the document was marked

 

 

3 Rutchey Exb. No. 2 for Identification.)

 

 

4 BY MR. KOBELINSKI:

 

 

5 Q. Mr. Rutchey, did you -- were there any

 

 

6 photos taken during the three site visits, the 129

 

 

7 sites?

 

 

8 A. I think we did do it for this one, I'm not

 

 

9 sure.

 

 

10 Q. Who would have those photos?

 

 

11 A. I'd have to look in my slides for that,

 

 

12 because we have gone there on and off on different

 

 

13 things.

 

 

14 Q. Would they be in just slide form or would

 

 

15 you also have photos, do you know?

 

 

16 A. They'd be slides.

 

 

17 Q. Okay.

 

 

18 Who would have taken the -- snapped the

 

 

19 photo or slide or whatever, done the camera work?

 

 

20 A. Yeah, I -- if I recall, I don't think we

 

 

21 did it for this particular project, we didn't take

 

 

22 pictures. I'm not sure.

 

 

23 Q. Okay.

 

 

24 A. I'd have to look.

 

 

25 Q. All right.

34

 

 

1 Mr. Rutchey, I'm showing you a composite

 

 

2 exhibit that we've marked as No. 2. There's actually a

 

 

3 number of different portions to it, but the first page

 

 

4 appears to be a photocopy of a possibly a file folder

 

 

5 which reads WCA-2A field data collection sites for 30

 

 

6 classes, 10-2-91 through 1-13-92. And all these

 

 

7 documents bear consecutive Bates numbers in the lower

 

 

8 right-hand corner, 1202881 all the way through 1203072.

 

 

9 Some of these are stapled together.

 

 

10 I'd ask you first of all, is this a -- one

 

 

11 entire file that you keep, this particular file?

 

 

12 A. It's not an entire file, it's a number of

 

 

13 different files.

 

 

14 Q. Perhaps -- because it was produced to us

 

 

15 in this consecutive order, I'd like you to go through

 

 

16 and perhaps see if you can identify each set, the first

 

 

17 portion of which is stapled together at 1202882. Do

 

 

18 you know what that particular document relates to?

 

 

19 A. This is the actual data that I sent to

 

 

20 John Jensen of the 30 ground truth sites and their

 

 

21 coordinate location.

 

 

22 Q. And it's actually referring to 129 sites?

 

 

23 A. Yes.

 

 

24 Q. Okay.

 

 

25 Now -- so this does relate to this initial

35

 

 

1 site identification of the 129 sites and the classes

 

 

2 that are listed there in this document. Where did you

 

 

3 get that information?

 

 

4 A. These are the classes that we determined

 

 

5 from looking during our aerial reconnaissance is the

 

 

6 site locations.

 

 

7 Q. Okay.

 

 

8 Just going through this top page here,

 

 

9 1202882, the first column there are a number of

 

 

10 numbers. What would that indicate?

 

 

11 A. Just basically it was a way of telling the

 

 

12 different ones apart, 1 through 129.

 

 

13 Q. So that's just essentially the numbers

 

 

14 that, for instance that first page we're on, 61, 63,

 

 

15 80, these are just the various sites; is that correct?

 

 

16 A. Um-hum.

 

 

17 Q. All right.

 

 

18 The next one is labeled class, I believe

 

 

19 you just stated that classification, you identified it

 

 

20 based upon your observations; is that correct?

 

 

21 A. Yes.

 

 

22 Q. I'm still on Page 1202882.

 

 

23 A. Yes.

 

 

24 Q. The next has UTM.

 

 

25 A. That's correct.

36

 

 

1 Q. What is that UTM, coordinate?

 

 

2 A. Universal Transverse Mercator

 

 

3 Q. That's your GPS coordinates there?

 

 

4 A. Yes.

 

 

5 Q. All right.

 

 

6 Next document that, at least it's stapled

 

 

7 together, bears Bates No. 2202885 through 887. And

 

 

8 could you -- do you know what this document reflects?

 

 

9 A. I'm going to tell you these don't look

 

 

10 like they're in order to me. And not to have my

 

 

11 folders here, my original stuff, I'm guessing basically

 

 

12 what I'm seeing here.

 

 

13 Q. All right.

 

 

14 Well, to the best of your ability do you

 

 

15 do you recognize what this could be?

 

 

16 A. It's basically -- it's classes grouped

 

 

17 together and their location, such as Class 1 is -- you

 

 

18 see all together and Class 2 and so on, and so on to

 

 

19 30.

 

 

20 Q. This is based upon the original 129 sites?

 

 

21 A. I believe so.

 

 

22 Q. Okay.

 

 

23 And the first column there says point old,

 

 

24 what does that mean?

 

 

25 A. I'm going to have to go back. We had two

37

 

 

1 sites, point old and -- well, not point old. And we

 

 

2 had new and old -- not new. It was basically two

 

 

3 different trips. We combined them together in the

 

 

4 final documents or data set.

 

 

5 Q. When you say two different trips, is this

 

 

6 all part of identification of the 129 sites where the

 

 

7 vegetation was?

 

 

8 A. Yes. Two different trips that basically

 

 

9 it might have been more than two trips, but at one

 

 

10 point in time we had one data set and then we had

 

 

11 another data set, then we combined them, the old data

 

 

12 set, old and new date set.

 

 

13 Q. Good classifications. All right.

 

 

14 Well, let me back up a moment. How long

 

 

15 did it take you to visit all 129 sites?

 

 

16 A. I think we did it over a period of two or

 

 

17 three months.

 

 

18 Q. Okay.

 

 

19 And what months would those be?

 

 

20 A. I think it says right here on the

 

 

21 beginning of Exhibit 2, 10-2-91 to 1 -- it look likes

 

 

22 13-92.

 

 

23 Q. Okay.

 

 

24 And did you go to all these sites?

 

 

25 A. Yes.

1 Q. I believe you said Les Vilchek did all the

 

 

2 identification. He also obviously went too.

 

 

3 A. Right.

 

 

4 Q. Did anybody else participate in the site

 

 

5 identification trips?

 

 

6 A. No.

 

 

7 Q. Approximately how many trips did it take?

 

 

8 A. Without having my folders, I don't recall.

 

 

9 Q. Okay.

 

 

10 And did you visit certain sites more than

 

 

11 once?

 

 

12 A. I don't think so.

 

 

13 Q. Okay.

 

 

14 I was just trying to understand why there

 

 

15 were two different data sets that you then merged.

 

 

16 A. I'm going to have to go back and look. I

 

 

17 remember that we collected one set and then we

 

 

18 collected another set, not repeating, two different

 

 

19 sets. We called one old and one new, and then we

 

 

20 combined it. That's the best of my knowledge, without

 

 

21 going back to my notes.

 

 

22 Q. All right.

 

 

23 Are those notes that you've produced to

 

 

24 us?

 

 

25 A. No, they're in -- it's basically in my --

39

 

 

1 yeah, they're probably here. But it's all -- not like

 

 

2 in my folders.

 

 

3 Q. Okay.

 

 

4 So you had field notes then from this

 

 

5 aspect of the study?

 

 

6 A. Well, those were already part of that.

 

 

7 Q. We're coming up on those.

 

 

8 A. Right.

 

 

9 Q. Okay.

 

 

10 Let's move on to the next document which

 

 

11 is Bates No. 120288 through 120291. And this likewise

 

 

12 has point new. My question would be that in the

 

 

13 approximately fourth column there, a number of data

 

 

14 points have 5 by 5 or 5 X 5. What does that refer to?

 

 

15 A. I believe that was if it had 5 by 5 pixels

 

 

16 or more, instead of a 3 by 3 pixel.

 

 

17 Q. Okay. All right.

 

 

18 Moving on then to next stapled portion of

 

 

19 this, which bears Bates No. 1202892 through 1202898,

 

 

20 and what would this relate to?

 

 

21 A. These are all out of the software called

 

 

22 PFINDER, and it's our software that we use to

 

 

23 differentially correct our field GPS data. This is the

 

 

24 output.

 

 

25 Q. Okay.

40

 

 

1 This is output from the unit you had out

 

 

2 in the field?

 

 

3 A. I'm not sure without having my folders in

 

 

4 front of me. I mean it's either output from the unit

 

 

5 in the field or it's the output after it's been

 

 

6 differentially corrected.

 

 

7 Q. All right. Let me just explore that for a

 

 

8 moment.

 

 

9 You have a GPS unit and it takes you to a

 

 

10 spot; is that correct?

 

 

11 A. That's correct.

 

 

12 Q. All right.

 

 

13 What are you -- how do you get to a spot

 

 

14 with a GPS unit?

 

 

15 A. You can enter way points into the GPS

 

 

16 unit, basically navigation points. You can navigate to

 

 

17 the point. The military's been jamming GPS signals

 

 

18 since the Gulf incident, so about the worse accuracy is

 

 

19 about a hundred meters. But there's -- we've found

 

 

20 that you can take that data set back to your office,

 

 

21 you have a community base station set up collecting GPS

 

 

22 data out of a known location that's been surveyed to

 

 

23 less than one centimeter. You can differentially

 

 

24 correct the recovery unit data to get an accurate

 

 

25 location of where you really were.

41

 

 

1 Q. Okay.

 

 

2 The unit itself, the recovery unit as you

 

 

3 called it, records then time and place, it was --

 

 

4 A. It records the time and the position.

 

 

5 Q. Okay.

 

 

6 Is that where you just press a button and

 

 

7 it does that for you, or how does it do it?

 

 

8 A. Pretty much press a button.

 

 

9 Q. So every time you got a spot that Les

 

 

10 would do a site identification you would press a

 

 

11 button, it would record the time and coordinates?

 

 

12 A. Right. We took a number of coordinates at

 

 

13 each place that we stopped, because that gives you

 

 

14 better accuracy the more you can average the data. And

 

 

15 basically we went to known benchmarks during our field

 

 

16 trips that we found, identified and checked the unit to

 

 

17 see how accurate we really were getting. And accuracy

 

 

18 ranged from three to seven meters.

 

 

19 Q. Okay.

 

 

20 That was during all your visits to the 129

 

 

21 sites?

 

 

22 A. Yes.

 

 

23 Q. Okay.

 

 

24 (Thereupon, a discussion was held off the

 

 

25 record.)

42

 

 

1 BY MR. KOBELINSKI:

 

 

2 Q. The next document is Bates No. 1202899

 

 

3 through 1202904.

 

 

4 Can you identify what that document is?

 

 

5 A. Again, this is output from the PFINDER

 

 

6 software for GPS, PFINDER software.

 

 

7 It looks like we can take, for instance,

 

 

8 the first page, Site No. 61, these are all the points

 

 

9 that were collected at that site. And then this is

 

 

10 like until -- before we actually average it and get

 

 

11 then a final number.

 

 

12 Q. Okay.

 

 

13 Are these -- looking at 61, you have

 

 

14 approximately 10 readings there. I didn't count it, is

 

 

15 that about right?

 

 

16 A. Yeah.

 

 

17 Q. 1, 2, 3, 4, 5. Yeah I think it's about

 

 

18 10. Is that all from the same holding spot or did you

 

 

19 actually move around to get those?

 

 

20 A. No, same spot.

 

 

21 Q. Okay. All right.

 

 

22 And then going to the next document

 

 

23 1202905 through 909, what would this be?

 

 

24 A. Again, this is output from the GPS PFINDER

 

 

25 software.

43

 

 

1 Q. Okay.

 

 

2 Just drawing your attention to the

 

 

3 leftmost column where it says text, and following

 

 

4 through, is that an identification of some sort?

 

 

5 A. In this case, not on that page, it

 

 

6 represents the site number.

 

 

7 Q. And the following pages?

 

 

8 A. Bug in the program. We were able to

 

 

9 overcome that bug by looking at the time in the second

 

 

10 column to determine where we were.

 

 

11 Q. All right.

 

 

12 In next document, 1202910 through 913,

 

 

13 what is that?

 

 

14 A. GPS PFINDER output.

 

 

15 Q. Okay.

 

 

16 Would that hold true likewise for the next

 

 

17 document, 1202914 through 2920?

 

 

18 A. That's correct.

 

 

19 Q. Okay.

 

 

20 And next documents 1202921 through 927?

 

 

21 A. Yes.

 

 

22 Q. Okay.

 

 

23 And then drawing your attention to the

 

 

24 next four documents bearing Bates numbers 1202928

 

 

25 through 936, what are these documents?

44

 

 

1 A. PFINDER GPS data output.

 

 

2 Q. Okay.

 

 

3 And looking at 1202937 there's handwriting

 

 

4 on there, it says this starts quote the new data set

 

 

5 quote. Now does that indicate that the new data set

 

 

6 essentially starts on December 3, '91 and went only

 

 

7 after that period? Is that how you'd read this?

 

 

8 A. Yeah, I'd say that's a fair statement.

 

 

9 Q. Does this help you recall as to why there

 

 

10 were two data sets?

 

 

11 A. No.

 

 

12 Q. On this sheet, this 1202937, there's

 

 

13 handwriting on here in a couple of places, it says

 

 

14 miss. What does that refer to?

 

 

15 A. I don't recall.

 

 

16 Q. Okay.

 

 

17 Whose handwriting is that; do you

 

 

18 recognize it?

 

 

19 A. It looks like mine.

 

 

20 Q. Drawing your attention to 1202939, the

 

 

21 document goes through 940, the leftmost column in

 

 

22 handwriting, what are these, the handwriting identified

 

 

23 as 96, 104, 54 as I'm going through?

 

 

24 A. I think this means -- dealing with the

 

 

25 accuracy of GPS being a hundred meters, that when we

45

 

 

1 actually went to a site that we thought was that

 

 

2 cluster, so the unit was off a hundred meters, it threw

 

 

3 us outside the cluster when we went back and checked

 

 

4 it. So we missed a cluster. So we couldn't use the

 

 

5 ground truth statement, because we weren't at that

 

 

6 location. That's what miss means, we missed.

 

 

7 Q. Okay. All right. Fair enough.

 

 

8 Well, just look at 1202939, just so I

 

 

9 understand your first eight readings, are those all the

 

 

10 same site or are those different sites?

 

 

11 A. I would say they're different sites.

 

 

12 Q. Each of these represents a different site?

 

 

13 A. Um-hum.

 

 

14 Q. All right.

 

 

15 And then quickly finishing up the

 

 

16 following two documents, 1202941 through 943, these are

 

 

17 likewise GPS documents; is that right?

 

 

18 A. Yes.

 

 

19 Q. Okay.

 

 

20 What would do you when you missed a site,

 

 

21 would you go back on a different day?

 

 

22 A. We would try to attempt to go back to it.

 

 

23 Q. Did you ultimately locate all 129 sites to

 

 

24 your satisfaction?

 

 

25 A. Initially there were more sites, there

46

 

 

1 were -- we just never could get to them. They -- some

 

 

2 of the clusters broke out to just 3 by 3 pixels, and if

 

 

3 they were jamming for a hundred meters we never found

 

 

4 that site. We couldn't include it.

 

 

5 Q. Of the 129 original sites that you set out

 

 

6 to do, how many did you ultimately get to?

 

 

7 A. No, there was more than 129. Initially

 

 

8 there was 150.

 

 

9 Q. Oh, I see.

 

 

10 And do I understand correctly then that

 

 

11 you were able to get to a hundred -- get to 129 of the

 

 

12 150?

 

 

13 A. Right.

 

 

14 Q. Okay. All right.

 

 

15 Then looking at Bates Nos. 1202944 through

 

 

16 1203016, the first page of which has -- states SFWMD

 

 

17 Environmental Sciences Digital Mapping Field Inspection

 

 

18 Sheet, what are these documents, sir?

 

 

19 A. These are the ground truth data, what we

 

 

20 saw there at the site depicting the vegetation.

 

 

21 Q. Okay.

 

 

22 And who kept these, who prepared these

 

 

23 documents?

 

 

24 A. Les Vilchek.

 

 

25 Q. And he prepared these out in the field?

47

 

 

1 A. No.

 

 

2 Q. Okay.

 

 

3 How would he record what he was seeing out

 

 

4 in the field?

 

 

5 A. On a piece of notebook paper or whatever,

 

 

6 then he came back in, he transcribed them to here.

 

 

7 Q. Okay.

 

 

8 Does he still retain his field book or his

 

 

9 field notes themselves?

 

 

10 A. I'm not sure. I sort of doubt it.

 

 

11 Those things, especially in your air boat,

 

 

12 they get all smudged up and get wet, so that's why we

 

 

13 did this.

 

 

14 Q. Now under a vegetation type, for instance

 

 

15 on the first page you have 1, 2, 3, 4, 5, 6, 7, 8, 9,

 

 

16 10, 11 categories, how are the 11 categories selected?

 

 

17 A. Those are some of the major things that we

 

 

18 thought were out there initially, so to make it easier

 

 

19 so we don't have write them down every time we went to

 

 

20 a site, we made a list.

 

 

21 Q. Okay. All right.

 

 

22 And I notice -- I draw your attention to

 

 

23 documents in the next rubber band set, which is 1203017

 

 

24 through 1273072. What are these documents?

 

 

25 A. The same. Ground truth information.

48

 

 

1 Q. All right.

 

 

2 And that is all -- this ground truthing

 

 

3 relates to the original visitation of the approximate

 

 

4 129 sites; is that correct?

 

 

5 A. I believe so.

 

 

6 Q. All right.

 

 

7 Are there any other documents then that

 

 

8 would relate to this portion or this task in the

 

 

9 project?

 

 

10 A. Just the digital data.

 

 

11 Q. Okay.

 

 

12 Once you received these field notes or the

 

 

13 field inspection sheets, what would do you with them?

 

 

14 A. Basically we went to each of the clusters

 

 

15 to see if they had clustered out uniquely, and we found

 

 

16 that wasn't the case, that a lot of them exhibited

 

 

17 heterogeneity within a single cluster within -- based

 

 

18 on our field reconnaissance.

 

 

19 Q. Okay.

 

 

20 Who did that work?

 

 

21 A. I did that work.

 

 

22 Q. What was the type of recovery unit you

 

 

23 used for the GPS?

 

 

24 A. A PathFinder Basic.

 

 

25 Q. All right.

49

 

 

1 You've done all the field work, you have

 

 

2 all these field notes, you come back, what's the next

 

 

3 step in the process?

 

 

4 A. Well, once we determined that everything

 

 

5 just didn't cluster out the way we had hoped, we used

 

 

6 that data set to do a supervised classification.

 

 

7 Q. All right.

 

 

8 How did you go about doing that?

 

 

9 A. It's basically the computer does -- they

 

 

10 do -- you feed it the ground truth information and run

 

 

11 a supervised classification and you look at the

 

 

12 results, see if they mean anything, see if you have

 

 

13 unique spectral signatures for the final data. And we

 

 

14 determined that, yeah, we came up with initially 19

 

 

15 unique signatures based on that kind of ground truth

 

 

16 information. And we used those, initially we saw some

 

 

17 problem areas and we attacked those and came up with

 

 

18 one additional class.

 

 

19 Q. What was the additional class?

 

 

20 A. Periphyton.

 

 

21 Q. All right.

 

 

22 Now with supervised classification, a

 

 

23 little more detail there. Did you select 19 classes

 

 

24 based upon your review of field notes and make a

 

 

25 determination there were actually 19 identifiable

50

 

 

1 classifications out there, or did the computer then

 

 

2 select 19?

 

 

3 A. No, it's based on supervised, based on

 

 

4 ground truth data.

 

 

5 Q. Okay.

 

 

6 So you took the data from your visits to

 

 

7 the 129 sites?

 

 

8 A. Um-hum.

 

 

9 Q. You yourself came up with 19 classes from

 

 

10 that?

 

 

11 A. Right.

 

 

12 Q. Okay.

 

 

13 Then you tell -- identify them to the

 

 

14 computer, the computer reruns the digital data to see

 

 

15 where it finds those classes?

 

 

16 A. Based on the spectral signature of those

 

 

17 data sites, basically the band information within those

 

 

18 areas. It's used in the supervised classification to

 

 

19 delineate based on these statistics.

 

 

20 Q. Okay.

 

 

21 Is this something you were doing or Les

 

 

22 was doing?

 

 

23 A. I was doing.

 

 

24 Q. All right.

 

 

25 Are there any documents related to that

51

 

 

1 particular activity?

 

 

2 A. Hard copy, no. Digitally, yes.

 

 

3 Q. What would have you digitally related to

 

 

4 this?

 

 

5 A. Well, we have all the seed locations for

 

 

6 the ground truth information. And basically all the

 

 

7 steps from there to the final supervised

 

 

8 classification, the output maps.

 

 

9 Q. Okay.

 

 

10 You didn't make hard copies of the maps

 

 

11 though, is that you're saying?

 

 

12 A. No. Well, I did make hard copies of --

 

 

13 not hard copies, no, no, I didn't. Just digital.

 

 

14 Q. Okay.

 

 

15 What was the next step?

 

 

16 A. Well the two problem areas, as I said, was

 

 

17 one was sawgrass/cattail sparse class, we knew from

 

 

18 aerial photography that we had a lot of, what we were

 

 

19 seeing in the southern end was periphyton that was

 

 

20 coming up as sawgrass/cattail sparse, so we wanted to

 

 

21 see if we can break that out. So we actually took that

 

 

22 class out of the supervised classification and ran an

 

 

23 unsupervised classification on that and broke it out

 

 

24 into, I believe it was five new spectral classes. We

 

 

25 look at each individually, looked at each of those

52

 

 

1 class individually and determined that we could break

 

 

2 out the periphyton from the sawgrass/cattail sparse

 

 

3 class. And then we came up with one additional class,

 

 

4 periphyton in the southern region.

 

 

5 Q. Okay.

 

 

6 I believe you said you knew from aerial

 

 

7 photography that the sawgrass/cattail part showing up

 

 

8 in the southern end was actually periphyton.

 

 

9 A. Um-hum.

 

 

10 Q. That aerial photography you were reviewing

 

 

11 as part of this particular project?

 

 

12 A. Yes.

 

 

13 Q. Okay.

 

 

14 What aerial photography were you using?

 

 

15 A. We had an area flown approximately at the

 

 

16 same time by Southern Resource Mapping at 1:24,000

 

 

17 scale, color infrared.

 

 

18 Q. That was by who?

 

 

19 A. Southern Resource Mapping.

 

 

20 Q. Now you're talking about the area, you're

 

 

21 talking about all of WCA-2A?

 

 

22 A. That's co
