Hi list, I was wondering if it is possible to feed raster maps as input into an external model and let the input be imported or be importable by GRASS as a result. The model is able to accept data of several biophysical parameters but for the moment only in 1D. Extending this to 2D with the use of rasterized data from GRASS would be a nice bonus. Or I will rephrase my question: Is there a standard command that can pipe raster data per pixel location into external code for evaluation and accept the output of this program? I know that there is shell access from within GRASS, but I don't know how it deals with the output of programs run in the shell from within GRASS.
Any advice, tutorials or howtos would be appreciated. Kind regards, Koen
