I have a point shapefile representing groundwater production wells with annual pumpage values distributed over a general area. I'd like to create a raster layer with each cell representing the potential production impact weighted by distance using the following expression:
outputraster = SUM n/i (Xi/log10(Di))
Where 'Xi' is the annual production of well i and 'Di' is the distance in meters from well i.
Since there a multiple wells scattered over a wide area, the resulting raster cell values should be highest based on the density of wells in a given area, proximity to a given well, as well as the production value of a given well.
I've begun by creating a raster dataset, but am having trouble initiating the map algebra expression.
Can this calculation be performed within the raster calculator tool?
I have very little coding experience and my work with rasters extends only to interpolation and basic raster algebra expressions.
