Hey, thanks for the video, but I've got one question; I don't understand why you use the specific formular in the raster calculator. could you explain this to me or do you have any scientific paper as a resource? This would help me a lot. Thanks in advance

Sir, I want you to help me share video on how to extract "soil moisture content' from Landsat 8 ETM+ image. Thanks for your usual assistance

what kind of units is that roughness in? The red classified field is from 0.1 to 0.4.. what?

[@peggiamjadi]

i think this is not Terrain Roughness Index, value of the field should be 0-4367 that means elevation. The above is Topographic Position Index
