I'm working with QGIS 1.8 (gdal 1.9.2) and GRASS 6.4.3...but on Windows 7.
I "just" want to merge my raster.
I've got a folder with 50 GTiff raster from Lidar data.
The aim is to merge raster before or after an import into GRASS in order to do some contours...
Before GRASS, I tried gdal_merge with QGIS's gui, without any option. I had an error message : "permission denied".
So I tried it in GRASS with r.patch but : First the gui don't allows you to select multiple raster at one time...
Then I don't know how to batch with GRASS functions in Windows...I tried the GRASS command line but can't locate in the current mapset (didn't understand how). When I had the windows installer for QGIS, this commandline putted you in the current mapset but it's not the case with the basic installation of QGIS.
I'm quite locked...Any help ?
