I'm trying to determine the ratio of building to vegetation change (i.e. how has the volume of built structures changed in proportion to the volume of vegetation) in a city over a period of five years. The LAS files for the first time period only have ground, noise, and unassigned class codes; the second period has building, ground, noise, rail, water, and unassigned.
My main difficulty has been creating a building raster for the first time period, which does not have class codes for buildings. Secondly, I need to determine the amount of vegetation in the region for both time periods.
I thought it would be a pretty simple process (perhaps it is), but it has proven rather challenging as I am somewhat new to GIS and Arcmap (10.6). This is for a LiDAR class and the area of interest is only a few sq. km.
Does anyone have any suggestions for how to proceed?
