When I initially imported the DEMs I pointed the GUI location wizard at
the appropriate prj.adf file and applied v.in.ogr to the hdr.adf file. These
were then re-projected to the project's location, patched together into a
mosaic. Since these cover only a very small area of the state I tried to
overlay a vector file on them but found the regions did not match. The
analytical area vector files have this region:
g.region -l
north-west corner: long: 122:23:37.862067W lat: 45:21:05.147704N
north-east corner: long: 122:16:26.271907W lat: 45:21:12.056489N
south-east corner: long: 122:16:11.941163W lat: 45:13:30.917967N
south-west corner: long: 122:23:22.563523W lat: 45:13:24.024495N
center longitude: 122:19:54.654969W
center latitude: 45:17:18.09468N
rows: 14238
cols: 9396
while the DEM mosaic has this region:
g.region -l
north-west corner: long: 97:07:59.896358W lat: 40:58:17.24843N
north-east corner: long: 97:01:02.580568W lat: 40:56:42.861876N
south-east corner: long: 97:03:55.617982W lat: 40:49:23.360021N
south-west corner: long: 97:10:52.177034W lat: 40:50:57.54634N
center longitude: 97:05:57.609434W
center latitude: 40:53:50.313005N
rows: 14187
cols: 10210
The latter is not anywhere near the state; it's somewhere much further east
and somewhat south of Oregon. How this came about is immaterial; I'll
re-import and re-project the three DEMs and hope to get them correct this
time.
Reading the Startup page I do not see a way to apply the proj.4 string to
create a new location on the command line. I know this is an option with the
GUI location wizard but do not see the appropriate '-c' modifier to do this
on the command line. If one of the startup manual options will do this, and
I'm just not seeing it, please point me to it.
