I'm very new in QGIS.
The task is to calculate the urban areas that has lack of pharmacies. I have buildings points with apartments count and existing pharmacies points. Then I made two raster heatmaps:
- Buildings heatmap weighed by apartments count (blue on the image)
- Pharmacies heatmap (red on the image)
I tried raster calculator with formula "apartments/pharmacies". The result looks like thruth (the more greener area, the more lack of pharmacies), but very ragged and exactly in bounds of pharmacies heatmap (not included other buildings areas)
And I cant go further.
What should be my direction?
