I calculated a series of Kernel Density Estimations in CrimeStat (because more parameters can be set than in the built-in tool in ArcGIS) and then imported the results into ArcMap. I wanted to combine all the Kernel Density Estimations to get an overall result by using the Raster Calculator so I can assign different weights to each Kernel Density Estimation. But the Raster Calculator only accepts actual rasters, while crimestat can only output vector grids. Is one of these solutions possible:
convert the vector grids to raster grids without loosing the original values? (when I use Polygon or Feature to Raster the grid looks totally different and I don't know why, it should look exactly the same only with a different format)
use a different tool instead of the Raster Calculator that accepts vector grids? I thought of a Spatial Join, but I need to weigh every layer differently and also the Spatial Join takes forever because of all the little grid cells.
