GRASS Help System |
To create a new GRASS location, you must supply the following information:
1. The coordinate system for the database
The user is asked to define default geographic region settings. This information will be saved in the special file named "DEFAULT_WIND" and stored under the "PERMANENT" mapset under the new location. Any mapset stored under this location will default to use of the geographic boundaries and cell resolutions shown in the "DEFAULT_WIND" file IF the mapset does not contain a file called "WIND" with these settings. These geographic boundaries should be large enough to encompass all of the data the user wishes to store under this location.
The user can modify the WIND file containing these settings under his own mapset later, in GRASS, as needed, using the g.region command. In the sample screen below, the user is asked to set default region settings for a UTM coordinate system database location in zone 10.
