[GRASS-user] Combining Rasters Help

[Slover, Kevin]

Been a while since I have used GRASS, and does it feel good to be back
using...

 

Am using 5.4, the latest compiled for Linux...

 

Trying to find the best way to approach combining ~4400 raster images
into one.  Description are 50 foot ESRI Ascii formatted DEMs imported
using r.in.arc.  When attempting to use a bash script to combine these
rasters using r.mapcalc, the error appears "ERROR: Too many open raster
files"

 

Does anyone know the limit of number of rasters that can be opened at
one time?  Or does anyone have a suggestion on how best to combine (do I
use r.combine??) the 4400 rasters as painless as possible?

 

Thanks!!
