I have a large number of polygons that are overlapping. I'd like to create a heat map and plan on using raster calculation to do this. My plan: to give each polygon a raster value of 1, and adding them up. But, when I convert to raster, it will only the entire shape so that all overlapping polygons have the raster value of 1.
Can I make it convert the individual polygons? I'm doing this in QGIS but come from an ArcGIS background, so either explanation may give me enough to get this done.
