Tips for Arc users
Working with your ArcGIS data
Importing ArcGIS Data
Grass provides convertors for importing ESRI shapefiles, e00 files, and many other GIS formats as well. The key Grass programs for importing vector formats are v.in.ogr (for ESRI shapefiles, MapInfo files, SDTS, TIGER, etc.) and v.in.e00 for e00 format.
Example 1: Import of Shapefiles
v.in.ogr dsn=/home/data/navigation_files output=Tracklines layer=Ship_Tracklines
This is the syntax for v.in.ogr in its' most basic form. The 'dsn' parameter corresponds to the location o disk of the vector you are trying to import.
