I'm trying to see if I can replicate the Esri solar suitability site example from this article.
I fail on the creation of the binary ground raster. I have made a Bare Earth raster from LiDAR ground points, and a surface raster from LiDAR first return points. The tool I use is Greater Than with first return as input raster 1, and ground raster as input raster 2.
I expect a raster with value 1 where the input1 raster is greater than the input2 raster, and value 0 where it is not greater. However, this is the result after the two input rasters:
The result should be a ground mask raster like this picture:
Okay, I have the raster I want after doing raster calc + 5 for the DTM and then using a CON expression concerning the DTM and DSM in raster calc to get the ground points raster.
