[GRASSLIST:5812] Re: v.in.e00 import error

I'm loading data from e00 files into PostGIS tables rather than GRASS, but
my approach might be useful.

I use avcimport to generate a coverage from the e00, then ogr2ogr to
generate shapefiles from the coverage & then import the shapefiles.

I know you shouldn't need to do this in GRASS, as v.in.ogr should cover
the extra step, but it is trivial & may provide an interim fix.

The only problem I've had was with 3 yrs of weekly e00 files from NOAA
which I found had no topology, so the derived PAL.shp files were garbage.
(They have since fixed this & it works well)

I've always found a shpfile to be a useful intermediate format as there
are so many excellent shapefile viewers around, which allow a check on
the reformatting process. (using QGIS right now, which interestingly draws
GRASS 5.7 vector maps about twice as fast as GRASS)


Cheers,
