Using ArcGIS 10.4.1 I am trying to build a map of the best state camp grounds to go camping in and also to use a telescope. I have the camp site shapefile from DNR and used lightpollutionmap.info to build a RGB.tif of light pollution for Michigan Lower Peninsula. I then converted the RGB.tif to colormap because I couldn't figure out what to do with the three bands.
I then converted the colormap to a polygon shapefile and I now have a range from 0(least)-7(Most) for the amount of light pollution for 38k ID's... and from here I am lost.
I want to find what camp grounds have the least total value of light pollution around it, say 50km. So I created a buffer around each camp site and now want it to register the total value of the converted polygon shapefile behind it(presumably the ones with the lowest total value are in the darkest areas for better telescope usage). I tried dabbling in merge and intersect but I can't seem to find what I am looking for.
