Hi I have 139 high resolution images, which I need to use as a background map for some digitizing work. Loading 139x3 layers into gis.m is a real pain and I can think of three workarounds.
1. Enter Rainer Krug and MapServer. I don't think my time frames allow for learning another software suite right now. 2. Use a script to build a .grc file with a group for gis.m. Before attempting this I would like to know if there are any limits to the number of layers that can be loaded. 3. Use r.patch to build one mosaic for each band. I currently have r.patch running. It's been going for about 10.5hrs and has reached 15%. Does this sound reasonable? I am starting to wonder if I'm expecting too much. Here are my region settings: GRASS 6.3.0RC3 (msunduzi_lo31):~ > g.region -p projection: 99 (Transverse Mercator) zone: 0 datum: wgs84 ellipsoid: wgs84 north: -3264858.18753122 south: -3295545.14772988 west: -92005.31394386 east: -43582.78768323 nsres: 0.35000012 ewres: 0.35000019 rows: 87677 cols: 138350 cells: 12130112950 Another question on the usage of r.patch: I have passed the option --verbose to r.patch and I am expecting the program to generate VERBOSE output, but all I'm seeing is the following: GRASS 6.3.0RC3 (msunduzi_lo31):~ > r.patch input=$MAPS output="aerial_mosaic.red" --overwrite --verbose r.patch: percent complete: 15% Comments and pointers most welcome.
