R: R: [GRASS-dev] WinGRASS: r.in.gdal projection issue

Hi Michael,
 
as Paul said, my problem is completely unrelated to EPSG entries and locations.
 
BTW, could you please give some examples of EPSG errors encountered by your students?
I never had problems in creating locations from EPSG codes with WinGRASS, and I also succesfully reprojected rasters and vectors within different locations.
 
Thsi said, JFYI, on next days I'll buy a new notebook with Vista intalled (I found a notebook with 2 HDD, so I'll have both Vista, preinstalled, and XP on the same machine). With it I'll try to build GRASS also on Vista: I hope this would help to fix the Vista problems encountered by your students.
 
Marco

Marco,

In most (all?) cases with my students, the problem locations were made by picking an EPSG code. This routine uses g.proj to create the location. The same issue may be affecting r.in.gdal I suppose.

	Hi Michael,
	
	I never had problems creating locations from EPSG codes. I suppose that it's another problem, probably related to GDAL.
	Now I check the questions by Glynn. I hope that we can fix it :-)

	Marco,
	
	I reported something similar a month or so back. Some of my students using
	WinGRASS would import an SRTM or other file--or they would make a location
	from an EPSG code. Then when they tried to reproject into another location,
	they'd get an error that there is no projection file.
	
	It seems most common (only?) with some latlon locations. UTM's seem OK. It
	is also somewhat erratic. I assume that it is either a g.proj error or a bad
	EPSG entry.
	
	Michael
