This release fixes some bugs discovered in the GRASS 6.4.0 source code and a few new features (over 560 updates to the source code with respect to 6.4.0 have been added). As a stable release 6.4 will enjoy long-term support. GRASS 6.4 brings a number of exciting enhancements to the GIS. Our new wxPython graphical user interface (wxGUI) is debuted, Python is now a fully supported scripting language, and for the first time since its inception with a port from the VAX 11/780 in 1983, GRASS runs natively also on a non-UNIX based platform: MS-Windows. GRASS differs from many other GIS software packages used in the academic and professional worlds in that it is developed and distributed by users for users, mostly on a volunteer basis, in the open, and is given away for free. The source code is also freely available, allowing for immediate customization, examination of the underlying algorithms, addition of new features, and faster patching of bugs.

[GRASS-user] problems deleting vectors with GRASS/osgeo4w
Hi all, I'm experiencing problems while deleting vectors from mapsets under GRASS installed with the osgeo4w installer under windows Seven. As I usually use GRASS under QGIS and I initially guessed it could be something with the plugin, but then I confirmed the problem under GRASS using the standard wxpython GUI. The problem does not seems to affect GRASS I have installed in Ubuntu linux (using the ubuntugis repository). Actually if I want to delete a vector map from a mapset I have to do the operation twice (Sat Nov 06 21:04:18 2010) g.remove vect=provin...@mapset3003 Removing vector provin...@mapset3003 Unable to delete file 'C:\Users\gio \Desktop/location3003/mapset3003/vector/provinces/hist' couldn't be removed provinces nothing removed (Sat Nov 06 21:04:19 2010) Command finished (1 sec) (Sat Nov 06 21:04:27 2010) g.remove vect=provin...@mapset3003 Removing vector provin...@mapset3003 (Sat Nov 06 21:04:28 2010) Command finished (1 sec) the first try seems to have the only effect to remove the dbf file (the vectors are imported shapefiles), while the second try deletes the remaining folder into the vector folder. Under QGIS: when hitting the delete selected map in the grass tools browser windows the following message shows cannot delete map provinces command: provinces g.remove.exe vect=provinces then the 0_polygon, 1_polygon, etc. do disappear but the name of the vector remains. Hitting refresh it produces cannot open vector ... in mapset ... on level 2 (topology not available, try to rebuild using the v.build module) Hitting again delete selected map just produce the error message cannot delete map provinces command: provinces g.remove.exe vect=provinces If I try to remove manually the vector trough the GRASS console (under QGIS) I get: C:\g.remove vect=pontos GRASS_INFO_MESSAGE(1800,1): Removing vector pontos GRASS_INFO_END(1800,1) GRASS_INFO_WARNING(1800,2): Unable to delete file 'C:/Users/gio/Desktop/locatio 3003/mapset3003/vector/pontos/hist' GRASS_INFO_END(1800,2) GRASS_INFO_WARNING(1800,3): couldn't be removed GRASS_INFO_END(1800,3) GRASS_INFO_WARNING(1800,4): pontos nothing removed GRASS_INFO_END(1800,4) C:\ while manually directly under GRASS I get GRASS 6.4.0 (location3003) g.remove vect=pontos Removing vector pontos WARNING: Unable to delete file 'C:\Users\gio \Desktop/location3003/mapset3003/vector/pontos/hist' WARNING: couldn't be removed WARNING: pontos nothing removed GRASS 6.4.0 (location3003) If someone can confirm is a GRASS problem in the osgeo4w installer I will be able to open a ticket. cheers -- Giovanni -- ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
