I am working with ArcGIS 10.6. I have used the minus spatial analyst tool to subtract two separate DEMs. The output raster comes out fine, but I am wondering if there is a way to render the output raster to show the positive and negative differences between the two input rasters instead of just showing the normal black and white shading?
Let me know if you need anymore information!

Hello again! I just have a question regarding the classification values. Obviously green is positive and red is negative. So, on the output raster, that would mean the green represents an increase in elevation and the red would represent a decrease in elevation correct? Or does green mean there was no change? Do these values have units like cm or meters correlated with them? I'm just trying to make sense of the numbers!
