the best thing to get any information about srs of your data is using
ogrinfo:
ogrinfo yourGISdata
compare then the ogrinfo output with the srs of your location
Helmut,
The projection information I see looks acceptable to grass:
Layer SRS WKT:
PROJCS["WGS 84 / Pseudo-Mercator",

I created a new location using EPSG 3857 but when I tried to import the
data using v.in.ogr from the GUI this results:
(Mon Oct 30 13:46:30 2017)
v.in.ogr input=/home/rshepard/data/species/fish/RedbandTrout_201201_v931.gdb layer=FishD_RedbandTrout_September2012 output=redband_trout2012
WARNING: Updating spatial reference with embedded proj4 definition
WARNING: Datum <unknown> not recognised by GRASS and no parameters found
(Mon Oct 30 13:46:31 2017) Command finished (0 sec)
Why is WGS_1984 not recognized by grass7.3.svn? Have I used the incorrect
EPSG code? And why doesn't grass find the correct datum when I let it create
a new location?
Thanks,
Rich
