Subject: [GRASS-user] Fixing the error: G_set_window(): Illegal
latitude for North

Hello:
I'm running GRASS 6.2 on Ubuntu Linux, supported by GDAL 1.4 utilities.
And I'm importing raster images in tif format (exported from ArcMap as TIF
files) using r.in.gdal, into a location created by manually entering the
bounding
coordinates and projection parameters. The bounding lat/long coordinates
contain the boundaries of the image that I am importing. The 'override
projection'
option is set.
When I press the Run button on the r.in.gdal dialog, the error occurs:
GRASS_INFO_WARNING(19479,1): G_set_window(): Illegal latitude for North.
From searching the lists for a solution, I dont see much that is of
help, but there
are some hints that this might be a software version conflict of some type.
Does anyone have any insight or a fix for this error? I have also seen the
error when trying to create a new location using the a geo-referenced
tif file.
Thanks for any assistance,

Rick,
"Illegal north" happens if the raster you're trying to import has more
rows (bottom-top) than the x resolution of your target. If you have only
1,000 rows height, but a raster that's 10,000 pixels high, then the
upper 9,000 pixels are outside your target location.
My usual approach is:
- When importing a raster, use the "create new location" option in r.in.gdal
(the location created by your first raster will be suitable for other
raster imports)
- Open the raster in that location
- Georeference the raster, using your lat-long location as the target
(process: i.group, i.target, i.points, i.rectify)
- Open the georectified raster in the target location
