Multiple DTMs

Discussion created by rutilio85 on May 5, 2011
Hi. For my thesis I need to work with Hec-GeoRas. I need to load, in a new analysis, multiple DTMs. I have .asc files but they can't loaded when I select multiple option (instead they are shown when I choose single -> grid option)
What is the right file extension for the multiple options? I really hope in your help.
