GRASS GIS Startup ScreenĪ good way of working is to first import reference dataįor a given project to the PERMANENT mapset and thenĬreate a new mapset for processing and analyzing the reference data.ĭata in the PERMANENT mapset is always accessible from other mapsets. Read the GRASS GIS Quickstart to learn more. Every location has a PERMANENT mapset which contains reference data. A location is a set of directories containing mapsets with a given coordinate system. The GRASS GIS database directory will contain locations which in turn contain mapsets. To start GRASS GIS, you need to set the GRASS GIS database directory, select a location, and then select a mapset.
