NAME
d.zoom.last.sh - Allows the user to change the current geographic
region settings interactively and tracks the last region settings.
(An addition to the GRASS display program
d.zoom).
(GRASS Shell Script)
SYNOPSIS
d.zoom.last.sh
DESCRIPTION
d.zoom.last.sh is a UNIX Bourne shell macro which
allows the user to interactively adjust the settings of the
current geographic region using a pointing device such as a
mouse, and automatically saves the last region settings.
The last region can be restored by a GRASS command:
- g.region region=last
- or
- g.region last
This script and the above restoring command function as an 'undo' in
editing.
NOTES
Only the last region is saved. When zooming multiple times,
regions before the last are NOT available. Region-file
'last' is reserved for d.zoom.last.sh.
