Hi guys, I found some interesting Free Erdas Imagine Spatial Modeler Library provided by Sterling Geo. The models have been donated by Sterling Geo employees. They are free to download and use.

I dont think ArcGIS has the capability to extract DEM from stereo pair image with their function except there is an extension out there you can use ERDAS or other remote sensing software to do that basically, you need images that overlap each other, and the DEM can only extracted on the overlap section only, IMHO

Respected am2, would you like to explain in brief how to download sentnal-2A data using SNAP. with regards
