[GRASS-user] merge 2 ascii-DEM/grass-DEM

[Helmut Kudrnovsky]

>The DEMs are over different areas beside each other, but within the mapset
and location,

ok, like this?

-------------------
|           |          | 
|raster |raster |
|   A      |   B     |
-------------------

>But when I load into NVIZ I can only chose one layer, DEMs in the mapset
listed....

you can only load raster A or raster B.

but try r.patch to combine both A+B to raster C and load 
this raster in NVIZ ... or try the virtual gdal raster data set, it this the
same like r.patch, but only 
virtual ...

best regards
