DESCRIPTION

Module r.futures.potsurface is a support tool for computing development probability surface based on maps and coefficients selected by r.futures.potential. It computes the initial probability surface used in the patch growing algorithm in r.futures.pga. It is not necessary to use this module, however it is useful to inspect the potential surface to better understand the input data and how the predictors influence the probability. The values range from 0 (unlikely to be developed) to 1 (high probability of development).

The inputs are the output file from r.futures.potential and the name of the subregions raster map.

EXAMPLES

r.futures.potsurface input=potential.csv subregions=counties output=pot_surface
Illustration of a potential
    surface in 3D, with a raster of the developed cells (in red) and
    undeveloped cells (in green) draped onto the surface.

Figure: We can visualize the potential surface in 3D and drape raster representing developed (red) and undeveloped (green) cells over it.
