I'm looking for a layer that will allow me to export an elevation value to a list of global locations. Can anyone tell me what layer to add or data source to use?

[JamesPreslar]

I have added a layer named Terrain, which indicates it can be used for analysis but when I export it, there is no elevation value applied.  What should I do to get the feet or meters above or below sea level to be applied to the points on my map, in an export file?

There is very little in the description to help with a possible solution/answer. 

Can you provide some screenshots and more information on the layer called "Terrain"?

What format are you exporting the terrain file to? Are you using a GP tool, right click options, Python,etc.?

What do you mean by global locations?

Hi George,

I'm just using Arc-GIS Online.  Terrain is a layer offered by Esri.  Here is a shot of the locations with the Terrain layer

I selected it because in the description it says: Use for Analysis: Yes. This layer provides data as floating point elevation values suitable for use in analysis.  The elevation values are what I am seeking.  I could not figure out how to get them to appear in an exported csv file.

I am not sure that there is a "direct" export to CSV. You could try Terrain To Points—Help | ArcGIS Desktop  in ArcGIS Pro, it does require 3D Analyst in Pro. Then export the points to a CSV

Note: There may be a cost in ArcGIS Online credits for the process.

You could also look at the following workflows: ArcGIS Imagery Workflows | ArcGIS

sorry for the delay in my response.

Terrain is an image service, and IDENTIFY will do this  

Identify (Image Service)—ArcGIS REST API: Services Directory | ArcGIS for Developers  

I think you can ignore many of the parameters

Let us know if you need more assistance

Hi Cody,

I’ll need to study this. It looks beyond my technical capabilities. I really thought there must be a simple way to export a csv with sea level values just like I do with lat & lon. This does not look simple. I don’t have time to look at it right now. I’ll make a project of it and try to figure it out in November.

Thanks
