#1452: wx location wizard doesn't ask for datum transform options because proj4 4.7.1's epsg file is broken ---------------------------------+------------------------------------------ Reporter: hamish | Owner: grass-dev@… Type: defect | Status: reopened Priority: critical | Milestone: 6.4.3 Component: Projections/Datums | Version: svn-releasebranch64 Resolution: | Keywords: location wizard, g.proj Platform: All | Cpu: All ---------------------------------+------------------------------------------
Comment(by pkelly): Hmmm, I have just read through the bug thread and am confused by all the discussion about PROJ. g.proj does not use PROJ at all (nor any files from the PROJ distribution) and strings passed with the proj4= option are interpreted by GDAL/OGR functions, so I don't see how changes to PROJ can fix the original problem in this report. I seem to remember there was an issue with the .csv files distributed by GDAL, which we include a copy of in lib/proj. We needed to avoid updating these to the latest version, because it included forced datum transformation parameters for many co-ordinate systems and datums, which meant that g.proj took these as given and no longer prompted for a user to choose their own parameters. Could the WinGRASS-specific issue perhaps be that the OSGeo4W version of GRASS is using a different version of the GDAL .csv files? Unfortunately I really don't have much time to look at this at present. But I don't think the bug should be closed, and the recent changes to g.proj were to fix a bug in the location wizard and were completely separate from this bug, as far as I can see. -- Ticket URL: <http://trac.osgeo.org/grass/ticket/1452#comment:36> GRASS GIS <http://grass.osgeo.org> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
