I am trying to import/open data files from www.streamnet.org but their GDB
format is quite different from what I've seen before now and grass-7.3.svn
will not open them. As an aside, I was thrown for a while looking for
OpenFileGDB in the v.in.ogr supported format list until I noticed it's been
renamed to ESRIFileGDB.
The results of running 'ogrinfo -al so' on the directory,
BullTrout_201201_v931.gdb/, produces this result:
Had to open data source read-only.
INFO: Open of `BullTrout_201201_v931.gdb/'
using driver `OpenFileGDB' successful.

There's no ESPG code there. So I wrote a proj4 file
+datum=NAD83 +ellps=GRS80 +lat_0=41.0 +lat_1=42.33333333333334
+lat_2=48.66666666666666 +proj=lcc +units=foot_us +x_0=2999999.999988
+y_0=0.0
Grass did not like it. There's no projection name in
../PERMANENT/PROJ_INFO:
name: unnamed
datum: nad83
ellps: grs80
proj: lcc
lat_1: 42.33333333333334
lat_2: 48.66666666666666
lat_0: 41
lon_0: 0
x_0: 2999999.999988
y_0: 0
no_defs: defined
towgs84: 0.000,0.000,0.000
and there are no data displayable.
Please suggest what projection values I should use on these data.
