[GRASS-user] GRASS 7.0.0
Dear Grass users, recently I installed GRASS 7.0.0 on ubuntu 14.04 (32 bits). When I tried to open by typing grass70 command I get the following error message: python: can't open file '/usr/lib/grass70/gui/wxpython/gis_set.py': [Errno 2] No such file or directory Received EXIT message from GUI. GRASS is not started. Bye I also have version 6.4.3 pefectly working from before, but I would like to migrate to Grass 70 as soon as posible. Any suggestions how to solve this issue? thanks in advance.. Rengifo Ortega___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] GeoTIFF, EPSG and GRASS
Hi! with GDAL i use EPSG:2972 to reproject any new raster i'm lead to work with. gdalinfo says: Coordinate System is: PROJCS[RGFG95 / UTM zone 22N, GEOGCS[RGFG95, DATUM[Reseau_Geodesique_Francais_Guyane_1995, SPHEROID[GRS 1980,6378137,298.2572221010002, AUTHORITY[EPSG,7019]], TOWGS84[0,0,0,0,0,0,0], AUTHORITY[EPSG,6624]], PRIMEM[Greenwich,0], UNIT[degree,0.0174532925199433], AUTHORITY[EPSG,4624]], PROJECTION[Transverse_Mercator], PARAMETER[latitude_of_origin,0], PARAMETER[central_meridian,-51], PARAMETER[scale_factor,0.9996], PARAMETER[false_easting,50], PARAMETER[false_northing,0], UNIT[metre,1, AUTHORITY[EPSG,9001]], AUTHORITY[EPSG,2972]] I've created the GRASS location from this same code, and all imports are successful. After exporting, the gdalinfo output is different: Coordinate System is: PROJCS[UTM Zone 22, Northern Hemisphere, GEOGCS[grs80, DATUM[unknown, SPHEROID[Geodetic_Reference_System_1980, 6378137, 298.257222101]], PRIMEM[Greenwich,0], UNIT[degree,0.0174532925199433]], PROJECTION[Transverse_Mercator], PARAMETER[latitude_of_origin,0], PARAMETER[central_meridian,-51], PARAMETER[scale_factor,0.9996], PARAMETER[false_easting,50], PARAMETER[false_northing,0], UNIT[metre,1, AUTHORITY[EPSG,9001]]] The PROJCS has lost its AUTHORITY parameter. Would someone know why this happens? Is there a way to fix this?

[GRASS-user] Question about Elevation Maps and Shaded Relief Maps
Hi, I have created an elevation map and a shaded relief map for the same area. I know there is a way that they can both be viewed simultaneously so that you can see the elevations (as indicated by color) and the shaded relief at the same time. Currently I am only able to view one at a time depending on which map is on top of the other. How can I change that so that I can see both maps at the same time? Thanks, Ben ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Using GRASS 6 and Xmonitors (d.mon), you can use the d.shadedmap module, which is actually a wrapper for d.his. See the help page for details on using the brightness option and an example. For 3D, in NVIZ do: nviz elev=dem color=overlay In the wxGUI you can put the overlay map on top and then change its opacity, right click on the map in the layer manager and select change opacity level, then move the slider somewhere in the middle 50%.

GRASS doesn't store the EPSG number in the location settings (well it can, but that's just for informational purposes) and only uses the actual coefficients used in the projection math. Literally the output of the 'g.proj -p' command. As definitive as EPSG codes are, they aren't always exact representations. (e.g. precision issues or added datum transform grid selection is sometimes used but not specified in the actual code definition. If you are lucky in these cases the extra terms are stored in a PROJ.4 string within the WKT, but that's a non- official extension AFAIK) Would someone know why this happens? Is there a way to fix this? perhaps this will do it: gdal_translate -a_srs +init=epsg:2972 in.tif out.tif Hamish ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
