I have a grid of 1 km points and a separate group of points representing RTK stations. (See image 1)
I want to create a 3rd value for the grid points that is proportional to the nearest reference station. Something like a mobile coverage map.
The problem is that I don't know how to separate the grid points by closest station and after that don't know how to include the distance between points in calculations. Is a grid of points even the best way to do this, or should I try to create a raster layer?
