location - A directory containing the GRASS mapsets accessible by a user within a given GRASS session. All mapsets stored under the same GRASS location must use the same map coordinate system. Typically, each GRASS location stores mapsets whose data are referenced to the same geographic region on the earth's surface. Each location directory contains the special mapset "PERMANENT" and other user mapsets. The variable $LOCATION_NAME denotes the user's current GRASS location.
