All,
I'm using GRASS 7.0 svn from a few weeks ago on Ubuntu 13.10 (not that I
think either is an issue). I have imported a fairly large shapefile from
here: http://www.nohrsc.noaa.gov/data/vector/master/rfc_us.tar.gz --
3084 KB. It imports just fine into a lat/long Location and displays just
fine, but when I try to reproject the map into a LCC projection
Location, I lose feature data for most of the 12 (large) polygons. These
polygons are displayed (unfilled with any color) in my map, and when I
query them I get no attribute info; the other polygons (about 4 out of
the 12) are fine. I have tried the reprojection several times with
identical results. This same result occured with GRASS 6.4.x as well.
I have successfully reprojected other vector maps from my lat/long
Location into my LCC Location without issues. It seems I have hit a
memory problem?? My computer has 8GB RAM.
I don't think that this is a memory problem. Sounds more like the
polygons are not closed after reprojection. You can open the file in the
digitizer to check. If that's the case, you can either correct manually,
or you can use v.clean.
