I have been asked to do a weighted suitability analysis using all vector based polygon feature layers (8 different layers). Each layer has been ranked from 1 to 8 in order of importance.
My problem is that I need to convert each layer into rasters in order to do a weighted overlay, but many of the layers only contain boundary polygons that don't contain specific values in which to create a raster with the ability to be analyzed in a weighted overlay.
I get once I have rasters, I can reclassify them to match to do the overlay, but what happens when one (or two or three) of the those layers contain only polygons that represent boundaries and not a range in values (ie. one layer containing 5 equally important zip-code boundaries, one containing 3 equally important zone features, one containing 44 equally important census tracts, etc.)?
It was also requested that I make it look cool like a heat map.
Can this be done with a weighted Kerenel Density (then how do you weight kernel density...create a "population" field with ranked values 1 thru 8?)?
I am using ArcGIS Desktop 10.5 Advanced with most all extensions.
