[GRASS-user] Importing Vector Data

Hi Bob,

Just starting to use GRASS myself, so this certainly isn't an expert
opinion. You can reproject the data using ogr2ogr without having to
bring it into GRASS at all.

The best resource I have found so far for GRASS is the book by Neteler
and Mitasova, "Open Source GIS, a GRASS GIS Approach".  It's not
cheap, but it seems to cover all the issues you are going to
encounter, including this one. It recommends that to import the data,
you should create a new location with the GUI and use the data set to
define the extents, then import the data using the v.in.ogr tool.

Apologies if that's old news to you, it's still relatively new to me.

Roger
