I have 1 vector layer (counties) and 1 raster layer (population density). I have tried merging these two, so that I can examine population density within a county, but I have had no luck. It just gives me columns with NULL.
I did the standard thing, which is to calculate Zonal Statistics. My raster layer is an asc file, and I have tried converting it to a tif. Nothing has worked.
I got my population data from the History Database of the Global Environment (HYDE).
Okay, it could be because my CRS projections aren't the same for the vector and raster layers. When I set both the same, however, the map completely screws out of whack, with the vector layer being off-map completely! What do I do?
