Re: [GRASS-user] mosaic raster files
30 minutes for 35 tiles.

Hi Michael Barton, Yes, I am running under Vista (sorry about that!). I will try 6.4R5 (just downloading).

Re: [GRASS-user] mosaic raster files
If you have GDAL 1.6 installed, you can use gdalbuildvrt to create a VRT of the files, and then link to this using r.external. This way you have a mosaic without duplicating the data.

Re: [GRASS-user] mosaic raster files
Hi Guys, I will try first download the latest SVN. In fact I am running a compiled version of 6.4R4, and I remember, on that time, few programs (like r.patch if I am not wrong) not compiled properly. Case it not work, I try r.series.

I forgot to write that I force resolution to be kept as is with "res=RESOLUTION". So "g.region -a res=SomeResolution rast=SomeRaster(s)" is ok or non-sense?

OR, given that you keep the "original" naming convention of the (elevation) tiles without the ".tif" extension (e.g. ASTGTM_N34E024_dem, ASTGTM_N35E023_dem, etc.), you can do: g.region rast=`g.mlist pat=AST*dem sep=,` -pa --- @Hamish: Something against using g.region's "-a" flag?
