I need to create a shapefile that only includes the vegetation in the scene. I was thinking I could take the DTM and the DSM and subtract the DSM from the DTM. Is there a way to do this in ArcMAP?

    Isn't the DTM the ground, and so you need to subtract the DTM from the DSM? – Martin Hügi Mar 17 '17 at 17:40

The Raster Calculator can be used for band math such as this. You would use an expression like the following:

float("DSM") - float("DTM")
