Hi,
I have several raster maps (aspect, slope, tand_curv etc.). I would like to combine these raster maps to one raster but without losing any information. As a result i would like to have one raster map with several attributes (aspect, slope, tang_curv etc.). And then I would like to check Pixel by Pixel
if slope = steep and aspect = North etc.
then
"Value of the checked pixel" + 10
else
....
Has anybody done this before? Is it possible to combine several raster maps
without losing any information?

Thaw what you described has SpatialGridDataFrame in R. Simply you can
import all raster data to one SGDataFrame and you can do there what you
need.... It seems, becouse I can't understand for what you need 1 file
instead of three or for and use mapcalc for that operation. Simply seems
that mapalgebra (r.mapcalc) it is what you realy need
