D is my Distance Raster (Dras). it is made.
I need help putting the formulae below into ArcGIS Pro Python or a raster calculator expression in ArcGIS Pro. It should only run on values where Dras < 150000. Where Dras >= 150000 the value becomes 4.
I have tried
4 * Exp(-1 * "%Waterways%")
And it works in Raster Calculator but I need to incorporate the 15000 part
