Trying to export elevation data from a line in a .txt output

[gs_meyer]

Hey all,

I am familiar with ArcMap but not that familiar with ArcGIS pro. In ArcMap the way to do what I would like to do is create a line using the "interpolate line" function, create a profile graph, right click that graph and click export data, then select ".txt" as the export file type. This would give you an elevation for each individual pixel along that line you created. 

I am trying to do exactly this in ArcGIS pro but am having little success. I have used distance and direction to create lines, then used the interpolate shape tool to create a new layer with the elevation data. If I create a profile graph, however, I can only export as an image - I have not been able to find a way to export the exact elevation values as a text file. I need to do this to import the elevation data to MATLAB.

If anyone has any suggestions that would be wonderful.

@gs_meyer This is a common workflow and thanks for posting your steps.

Please review: Interactive elevation profile basics

There are multiple export options including CSV and GDB table

Hello, 

I have followed the steps provided however I am unable to export the profile elevation data. If I click export for the profile graph, I only get an option to save it as a graphic, not a table as shown.

@gs_meyer Thanks for trying this alternate workflow. The elevation data being used must have the proper attribution and allow export. Here's what I got: 

Export as csv:

ID	Distance	Elevation
1	0	2958.4971750815084
2	8.655678718001091	2958.4971750815084
3	17.311357436002183	2958.4971750815084
4	25.967036154003274	2958.4971750815084
5	34.622714872004366	2958.474889195204
6	43.27839359000545	2958.3095440401494
7	51.93407230800655	2958.3095440401494
8	60.58975102600764	2958.3095440401494
9	69.24542974400873	2958.4569236734096
10	77.90110846200982	2958.857936267089

The UI in screenshot looks different than the interactive Elevation Profile tool located in the Exploratory 3D Analysis drop-down menu in the Workflows group on the Analysis tab.

So I had the same problem as @gs_meyer and eventually figured this one out. 

1. Generate your Surface in a Map view.
2. Draw a profile using a line feature class
3. Use the 'Interpolate Shape' tool to create a 3D feature by interpolating z-values from the surface
4. Open attribute table of new 3D feature... (Oh no! There is no distance or elevation information!)
5. Click 'View' > Convert > Local Scene 
6. In your Scene, add your surface model as a source for Ground.
7. Select the 3D line feature for which you want to export X (Distance) and Y (Elevation) data
8. Click 'Analysis' > Exploratory 3D Analysis > Elevation Profile
9. Select 'Along a Line' then 'Apply'
10. Watch the ArcGIS Pro magic happen
11. In the new 'Elevation Profile' window, click 'Export Graph' in the top right corner and select preferred output (Image, Feature, Geodatabase Table or CSV Table).
12. Reap the rewards!

It is disappointing this simple process in ArcMap now involves several more steps in ArcGIS Pro.

Goodluck everyone!
