[GRASS-user] Execution failed g.proj.exe
Dear List, I just installed WinGRASS-6.4.0svn-r39740-2-Setup.exe on Windows XP professional and when starting the system using the spearfish database I get the message Error in command execution: Execution failed g.proj.exe -p . Any ideas?

Re: [GRASS-user] using GDAL to view netcdf files in GRASS

I tried using gdal_translate -of GTiff -b 1 NETCDF:FILE.nc:Outfile Outfile.tiff You probably need to specify a coordinate system, too. Do this with the -a_srs option. See http://www.gdal.org/gdal_utilities.html for details. The easiest way is using the epsg codes. On my system, I can find them by: cat /usr/share/proj/epsg | grep -i lambert -A 1 There is also a list at (http://www.epsg-registry.org/) - look under Projected CRS type. Choose the one that you need, and amend your code. e.g. gdal_translate -of GTiff -a_srs epsg:12345 -b 1 NETCDF:FILE.nc:Outfile Outfile.tiff You might also need to warp your map into the new projection gdalwarp -t_srs epsg 12345 Outfile.tiff Outfile_warped.tiff See the first parts of this tutorial for details http://blog.thematicmapping.org/2008/03/generating-map-tiles-with-gdal2tiles.html Hope that helps, John -- Dr John Stevenson Postdoctoral Research Associate School of Earth, Atmospheric and Environmental Sciences Williamson Building (Room 2.42) University of Manchester Manchester M13 9PL, UK tel. +44(0)161 306 6585; fax. +44(0)161 306 9361; john.steven...@manchester.ac.uk ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Peng Du wrote: I am dealing with a satellite image which has N bands, each band of size row x col. Is there any way to read one column of a certain band or all the bands of a certain point? I only found G_get_raster_row which works for row. You can use G_set_window() (Rast_set_window() in 7.0) to control which samples are returned for each row. E.g. for column n: struct Cell_head cellhd; ... G_get_set_window(cellhd); cellhd.west += cellhd.ew_res * n; cellhd.east = cellhd.west + cellhd.ew_res; G_set_window(cellhd); Then, each call to G_get_raster_row() etc will store a single value in the buffer. However, reducing the number of columns won't have any noticeable effect upon speed, as the library reads and decompresses entire rows. If you want to process maps in column-major order, you should create a transposed copy in a temporary file or in memory. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] *Direction* to nearest vector?
Just a guess... Maybe v.distance? Create a point raster, on point for each cell in your raster. Run v.distance and look for the to_angle value calculated. Then convert the points back to raster v.distance man page... http://www.ces.iisc.ernet.in/grass/grass64/manuals/html64_user/v.distance.html Or you could try something with the r.distance module and the east1,north1 values Good luck daniel On Mon, Nov 30, 2009 at 4:44 PM, Jonathan Greenberg greenb...@ucdavis.edu wrote: GRASSers: Is there any way to generate a raster in which the pixel values are the directions (in radians or degrees) to the nearest vector object, e.g. a point, line, or polygon (nearest being calculated as Euclidean distance)? --j -- Jonathan A.

[GRASS-user] Finding Missing Point
I have a map that's supposed to have 3 points (sites) on it, all relatively close together. The geographic coordinates were projected to lcc using v.proj and the region's boundaries and parameters adjusted to the map using 'g.region vect=sites'. My problem is that only two sites display, and the relative x values are switched (that is, the one on the left should be on the right). How should I go about determining what went wrong?

Re: [GRASS-user] Re: i.atcorr with MSS band 5,6,7
i.atcorr supports the MSS sensor aboard Landsat 5 and is not applicable to Landsat 1 data (nor landsat's 2,3 or 4). In-order to atmospherically correct landsat 1 data with i.atcorr you'll need to add support for it. It's not hard and I would be willing to spare what free time I can to help you but the first step, and possibly the most difficult, is to find the spectral response curves for the RBV and MSS sensors aboard Landsat 1.
