I'm looking for a way to join polygons to a density function for some other feature of interest.
- make density raster from feature set of interest, using point/line/kernel density
- sum raster inside output geometry (for polygons) or just sample it (for points)
This seems inefficient as I have to calculate a density raster for many points I won't even use. Is there a tool that does the same thing but without the raster? This would be like a kernel-density-aware spatial join, or a kernel density function that outputs to a preexisting geometry rather than to a raster.
