Hi All, I have been pondering this for a while and would like to know if people on this list think the following would be a feasible/useful addition to GRASS (7):
How about, in addition to the MASK raster, we'd also allow the user to specify a COST raster? This would allow all raster modules that currently use an euclidean distance measure (KDE, IDW, ...) to use a cost-based measure instead, without adding more options to the individual modules. In addition to the COST raster, we could modify the basic distance function in the GRASS GIS lib to automatically return a cost-based result if the COST raster is present. This way, there would have to be no or only minimal modifications to existing modules. For anisotropic cost distances, we could allow a DIRECTION raster.
