[GRASS-user] Map Boundaries: Identifying and Correcting

[Rich Shepard]

   Apparently I have messed up my data files. Five themes have statewide
coverage. I created a location for them and imported all into that same
location. According to 'g.region -l' the bounds are:

north-west corner: long: 124:48:00.583367W lat: 46:27:13.861387N
north-east corner: long: 116:24:06.129053W lat: 46:27:39.570528N
south-east corner: long: 116:43:23.433529W lat: 41:37:52.520783N
south-west corner: long: 124:27:46.455431W lat: 41:37:28.813261N
center longitude:  120:35:49.150345W
center latitude:   44:02:33.69149N
rows:              537298
cols:              645238

   But, when I try to display one of these themes ('lentic') I'm told that
the boundaries are outside the current region:

GRASS 6.4.0svn (Oregon):/usr4/grassbase/Oregon > d.mon x0
using default visual which is TrueColor
ncolors: 16777216
Graphics driver [x0] started
GRASS 6.4.0svn (Oregon):/usr4/grassbase/Oregon > d.vect map=lentic
The bounding box of the map is outside the current region, nothing drawn.

   The same result comes from my trying to display the maps for 'lotic,' and
'huc.' I can display the maps for the 'highways' and 'dams' themes.

   While it might be nice to know how the boundaries became FUBAR, it's more
important for me to learn how to determine the boundaries of those
non-displaying maps and how to reset those boundaries to the default for the
statewide coverage.

TIA,

Rich
