I am looking for a way to calculate the following.
I have a raster file with my so-called starting points.
I want to calculate the number of cells or the area of the cells between the starting point and the next starting point (the so called end-point). Making a subset of the cells would also be fine.
The points can be linked to each other using the flow direction (ddm30 raster file).
Anyone who has suggestions how to start?
