00:00:08.710 --> 00:00:12.404
In this demo, you'll learn how
to create a topographic profile

274451c4-4782-4932-9bdd-b4628186e06a-1
00:00:12.404 --> 00:00:15.160
in Arcgis Pro using data that is
not of Earth.

dd2a7b2a-9c9b-47bb-b335-3fd095ec65dd-0
00:00:15.830 --> 00:00:19.156
So here in this example we have
a part of Jezero crater which is

dd2a7b2a-9c9b-47bb-b335-3fd095ec65dd-1
00:00:19.156 --> 00:00:21.460
where the Perseverance Rover
landed on Mars.

f5559dc3-2b1f-4db5-8409-fe2f561527a5-0
00:00:22.540 --> 00:00:26.311
And we're working with Mars
Reconnaissance Orbiter Context

f5559dc3-2b1f-4db5-8409-fe2f561527a5-1
00:00:26.311 --> 00:00:30.338
Camera data. So here we have the
Context Camera orthomosaic of

f5559dc3-2b1f-4db5-8409-fe2f561527a5-2
00:00:30.338 --> 00:00:34.493
this area and also the elevation
model that was derived from the

f5559dc3-2b1f-4db5-8409-fe2f561527a5-3
00:00:34.493 --> 00:00:35.900
Context Camera images.

3bb251f2-5146-4f61-a344-b81479e67fe8-0
00:00:37.870 --> 00:00:41.471
The first thing that we need to
do to create a topographic

3bb251f2-5146-4f61-a344-b81479e67fe8-1
00:00:41.471 --> 00:00:44.280
profile is to create a 3D scene
of this area.

697689b2-2f4b-4eb7-9abf-a301449f76f8-0
00:00:45.590 --> 00:00:48.782
To create a 3D scene, we'll go
to the View tab and click on

697689b2-2f4b-4eb7-9abf-a301449f76f8-1
00:00:48.782 --> 00:00:51.762
convert and this is a small
area, so we'll select local

697689b2-2f4b-4eb7-9abf-a301449f76f8-2
00:00:51.762 --> 00:00:55.220
scene. If you're working with a
very, very large area, you would

697689b2-2f4b-4eb7-9abf-a301449f76f8-3
00:00:55.220 --> 00:00:58.520
do global scene, but in this
case it's small. We'll do local.

8e9c58d5-9ddc-4b88-9cb1-556fe31bb599-0
00:01:01.330 --> 00:01:04.515
Depending on the size of your
data set, this may take a few

8e9c58d5-9ddc-4b88-9cb1-556fe31bb599-1
00:01:04.515 --> 00:01:07.010
minutes. And now we have our 3D
scene created.

4cc2c6de-193f-4c26-9119-68d475281db5-0
00:01:08.210 --> 00:01:11.378
One other step that we need to
do here - since we're not

4cc2c6de-193f-4c26-9119-68d475281db5-1
00:01:11.378 --> 00:01:14.657
working on Earth - we need to
change the default elevation

4cc2c6de-193f-4c26-9119-68d475281db5-2
00:01:14.657 --> 00:01:17.770
surface. The default elevation
surface is a terrestrial

4cc2c6de-193f-4c26-9119-68d475281db5-3
00:01:17.770 --> 00:01:20.549
elevation data set. You can see
it here listed as

4cc2c6de-193f-4c26-9119-68d475281db5-4
00:01:20.549 --> 00:01:22.050
WorldElevation3D/Terrain3D.

a69f6daf-f452-451c-ae70-5ffcbb47e6bb-0
00:01:22.750 --> 00:01:25.890
To change this, right click the
Ground Surface here.

3b30e166-cfbe-401d-b5eb-9d60294605b8-0
00:01:26.510 --> 00:01:28.580
And select add elevation source
layer.

803c0d85-66f3-43ea-8fc4-9be36e599e77-0
00:01:30.020 --> 00:01:33.998
You'll navigate to wherever your
elevation data set is. In this

803c0d85-66f3-43ea-8fc4-9be36e599e77-1
00:01:33.998 --> 00:01:37.913
case, I'm in the right folder
already, and I'm going to select

803c0d85-66f3-43ea-8fc4-9be36e599e77-2
00:01:37.913 --> 00:01:39.530
the Jezero crater CTX DEM.

113b3dc2-2cd9-4bfd-a29d-8fdb31887036-0
00:01:40.390 --> 00:01:41.120
And click OK.

4d88034d-9229-4576-aa30-9e97db79cdfe-0
00:01:45.120 --> 00:01:47.877
We've now set this as our
elevation surface layer. We can

4d88034d-9229-4576-aa30-9e97db79cdfe-1
00:01:47.877 --> 00:01:49.780
go ahead and get rid of that
other one.

16b3c36f-d528-4139-96f6-788fd085b58e-0
00:01:50.490 --> 00:01:52.370
So we'll right click it and say
remove.

1b1d3015-34bd-4af9-b19e-a52360c80e1f-0
00:01:52.980 --> 00:01:55.778
And now that terrestrial
elevation data set is gone. It's

1b1d3015-34bd-4af9-b19e-a52360c80e1f-1
00:01:55.778 --> 00:01:58.722
not in there anymore, and all
we're working with is the data

1b1d3015-34bd-4af9-b19e-a52360c80e1f-2
00:01:58.722 --> 00:02:00.169
set that we want to work with.

3062f298-7026-4fcf-bda0-e494f27465f9-0
00:02:01.390 --> 00:02:04.137
Now we have our elevation
surface defined. We can go ahead

3062f298-7026-4fcf-bda0-e494f27465f9-1
00:02:04.137 --> 00:02:05.860
and create our topographic
profiles.

67e148dd-23fa-4e98-ad85-99ae77dd791c-0
00:02:06.600 --> 00:02:08.750
To do this, we go to the
analysis tab.

dec834f5-b0b0-4696-9e07-a92f6853168c-0
00:02:09.730 --> 00:02:13.236
And you'll click on the
exploratory 3D analysis icon and

dec834f5-b0b0-4696-9e07-a92f6853168c-1
00:02:13.236 --> 00:02:15.390
select the elevation profile
tool.

3be83f06-069d-4c93-9d4e-8803a8697eb8-0
00:02:18.350 --> 00:02:20.925
We're not working in feet. We're
working in meters, so we'll

3be83f06-069d-4c93-9d4e-8803a8697eb8-1
00:02:20.925 --> 00:02:21.770
change that quickly.

38aeabdb-7bd1-47f0-88a3-631692f44c7c-0
00:02:22.820 --> 00:02:25.997
Here you can now click on the
map to draw lines to create your

38aeabdb-7bd1-47f0-88a3-631692f44c7c-1
00:02:25.997 --> 00:02:29.123
topographic profiles. You also
have the option of adding them

38aeabdb-7bd1-47f0-88a3-631692f44c7c-2
00:02:29.123 --> 00:02:32.351
from a layer. So if you already
have a feature class or a shape

38aeabdb-7bd1-47f0-88a3-631692f44c7c-3
00:02:32.351 --> 00:02:35.175
file in which you have lines
drawn for your topographic

38aeabdb-7bd1-47f0-88a3-631692f44c7c-4
00:02:35.175 --> 00:02:38.402
profiles, you can pull that in
here. If you click on the map to

38aeabdb-7bd1-47f0-88a3-631692f44c7c-5
00:02:38.402 --> 00:02:40.420
draw lines, you click once to
start it.

a883bc1f-3ba1-432e-8480-9c6cbc664768-0
00:02:41.240 --> 00:02:43.110
And then double click to end it.

29e62f6c-9818-4de0-bd21-c36b2f41bc79-0
00:02:44.420 --> 00:02:47.197
And that will automatically pull
up your profile. You can move

29e62f6c-9818-4de0-bd21-c36b2f41bc79-1
00:02:47.197 --> 00:02:49.710
your mouse along it and you'll
see up top where you are.

42be8742-3f6e-414d-b9b9-a352dc004661-0
00:02:51.480 --> 00:02:52.140
In the data.

810db255-5e3e-4287-9d2e-5ae079c9c5c4-0
00:02:53.030 --> 00:02:56.394
And this tool pulls whatever the
highest resolution elevation

810db255-5e3e-4287-9d2e-5ae079c9c5c4-1
00:02:56.394 --> 00:02:59.867
data is. So if you have multiple
elevation datasets listed over

810db255-5e3e-4287-9d2e-5ae079c9c5c4-2
00:02:59.867 --> 00:03:03.286
here, it will use whatever the
highest resolution data set is.

810db255-5e3e-4287-9d2e-5ae079c9c5c4-3
00:03:03.286 --> 00:03:06.760
In this case, we only have one,
but you can have more than one.

2e6350cc-da3f-45b6-93eb-454ef71d03b4-0
00:03:08.090 --> 00:03:10.427
If you want to change your
profile line. If this isn't

2e6350cc-da3f-45b6-93eb-454ef71d03b4-1
00:03:10.427 --> 00:03:12.850
exactly where you want it, you
can click on the handles.

47feaac0-bd4f-44dc-9311-e3700f058a60-0
00:03:13.450 --> 00:03:16.745
And move it around and it will
automatically update as you move

47feaac0-bd4f-44dc-9311-e3700f058a60-1
00:03:16.745 --> 00:03:16.900
it.
