GRASS Locations

Standard EPSG 4326, 21037, 32737

1. In QGIS/GRASS Plugin Create new mapset
2. Choose the database (path_to_GIS_data)
3. Create New Location: WGS84LL ("Projected": EPSG:4326)*
   
4. Default Wind: Tanzania
   
5. Choose a name for the Mapset (ARUMERU)

* Repeat for WGS84UTM37S (EPSG:32737) and for ARC60UTM37S (EPSG:21037)
