[GRASS-user] mapcalc

[Hendrik Hoeth]

Thus spake Rebecca Bennett (rabennett at ymail.com):

> I would like to use r.mapcalc to fill the null cells of one raster
> with the value of the same cells from in a second raster (while
> leaving all other cells as they are in the first raster).

rasterA="if(isnull(rasterA), rasterB, rasterA)"
