I have a point layer representing wells in a region. i am able to rasterize it and write the well density into the raster as integer, so far so good.
What I aim for is to create a raster with values in each cell that weight the distance to well-bearing-cells. Raster cells with wells in them (cell value > 1) should get assigned a value of 1.0, cells more than 100km away from well-cells should get a value of 2.0. The cells in between should get values ranging from 1.01 to 1.99, depending on their distance to a well-bearing-cell.
I am not the most profound GIS profesisonal and lack a good approach to that problem. The heat map function seems to go into that direction but i dont get into the finer controls of it. The "weigthed distance to power" tool could be it but if the regression is to a power than its a exponential function (I might be wrong here?) while I am looking to implement a linear function.
Hope someone might have an idea.
I am used to QGIS but getting into R, so I might be able to handle solutions going in that directions.
