Hi all.
I can't focus a problem in a right way. Perhaps someone could give me some
hints.
I've got three maps:
* vector map of areas representing subwatersheds
* raster map of soil types
* raster map of land uses
(well, I could transform the vector files into raster if it is needed)
In order to run an hydrologic model I need to know for every subwatershed,
the area of every different combination of soil-landuse.
I've also got Postgres tables that says what kind (label) of land use
corresponds to each code, and the same for the different soil types.
So I would like to create some kind of report that could find all
combinations for every subwatershed and say something like:
COMBINATION SUBWATERSHED AREA(ha)
soil1-landuse1 1 45
soil1-landuse2 1 185
soil2-landuse1 1 54
soil1-landuse5 2 32
...
for all watersheds
I've thought that perhaps with the help of R (or R-Postgres in someway) this
could be possible but I can't find my way.
Thanks a lot for your ideas,
Best wishes,
Javier
