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 (for ESRI shapefiles, MapInfo files, SDTS, TIGER, etc.) and for e00 format.

Example 1: Import of Shapefiles into Grass dsn=/home/data/navigation_files output=Tracklines layer=Ship_Tracklines dsn=Ship_Tracklines.shp output=Tracklines layer=Ship_Tracklines

This is the syntax for in its most basic form. The dsn parameter corresponds to the directory path of the vector you are trying to import. You can enter a full or relative path. The output paramter, aptly enough, is the name of your output Grass vector. The layer parameter is the name of the input vector, be it shapefile, MapInfo file, or what have you.
