I am trying to run the following analysis in QGIS 3.2.
- raster layer (with population estimates from LandScan)
- vector layer, with points (each point represent the location of a mobile cell tower)
I want to define for every cell of the raster layer (masked for one specific country):
- it's value
- it's distance (preferably in meters) to the closest point/cell tower.
The output can be another raster layer or any format that can be exported for further analysis in Excel.
I have tried so far Raster -> Nearest Neighbour, which generates a binary raster map with no values, so I am clearly doing something wrong.
A snapshot of my current setup is below. Blue dots are cell towers, a brown gradient is the raster data.
