Blaackmona Posted March 10, 2014 Report Share Posted March 10, 2014 Hey, I am to create a DTM using raster calculator in ArcGIS 10.1. The base is a raster data. I need to change the resolution and derive DTM using raster calculator. I do not have any other specifications given. I have some difficulties with how to use raster calculator in this case, which funtions will result in DTM. I was wondering if anyone could help me or give some hint. Thanks a lot!

Svenne68 Posted March 11, 2014 Report Share Posted March 11, 2014 What kind of data do you have to begin with ? As I think you need one with "obstacles" and one without.....then it would be (obstacles - without)....but they have to have the same resolution then, otherwise you must resample fist Quote Link to comment Share on other sites More sharing options...
