Is it possible to export / extract Elevation or Surface information from Arc GIS Earth in any format? If yes , how?
the measurements procedure is covered in the help files for Earth
Guided tour—ArcGIS Earth | ArcGIS
Thanks for a very quick response.
My interest is to extract a 3D Surface of a chosen polygon. Is that possible?
If it isn't listed in the link, then it is not possible. You need a full DEM and ArcMap or ArcGIS Pro for those types of things. Earth is not designed for the heavy lifting.
I have ArcGIS Desktop trial version. Is it possible to extract a DEM or 3D
Surface there? How?
You need a DEM. You will have to source that yourself. Many governments provide suitable data for free. Dr Google is your best guide.
This link will provide you with an overview 3D GIS | ArcGIS for Desktop but any of this assumes some familiarity with ArcMap or ArcGIS Pro. If you have the skills and the data, then it is a realitively simple task.
