MAPSET FILES:

Two of these files, "DEFAULT_WIND" and "MYNAME", are special files found only under the "PERMANENT" mapset under each "location".

## $GISDBASE

                               |

## $GISDBASE/$LOCATION_NAME

                               |

## $GISDBASE/$LOCATION_NAME/$MAPSET

                               |

## DEFAULT_WIND WIND MYNAME SEARCH_PATH ..........

The "WIND" file is the user's "current window", and contains the geographic boundaries and data resolution used by GRASS programs. The user can alter these settings as he wishes during a GRASS session.

The "DEFAULT_WIND" file contains the geographic boundaries and data resolution to be used if the user's current mapset does not contain a "WIND" file with this information. This file is stored under the PERMANENT "mapset" directory.

The file "MYNAME" simply contains the name of the geographic region to which maps under the "current location" refer. For example, this file might simply say "Spearfish, SD". This file is stored under the PERMANENT "mapset" directory.

The "SEARCH_PATH" file contains a listing of the "mapsets" whose data files the user wishes to use, in the order these "mapset" directories are to be accessed. This allows a user to have non-destructive access to other relevant maps for a geographic area without modifying other users' original data. It is possible to prevent others' access to your mapset directories.
