Helmut,

   The projection information I see looks acceptable to grass:

Layer SRS WKT:
PROJCS["WGS 84 / Pseudo-Mercator",
     GEOGCS["WGS 84",
         DATUM["WGS_1984",
             SPHEROID["WGS 84",6378137,298.257223563,
                 AUTHORITY["EPSG","7030"]],
             AUTHORITY["EPSG","6326"]],
         PRIMEM["Greenwich",0,
             AUTHORITY["EPSG","8901"]],
         UNIT["degree",0.0174532925199433,
             AUTHORITY["EPSG","9122"]],
         AUTHORITY["EPSG","4326"]],
     PROJECTION["Mercator_1SP"],
     PARAMETER["central_meridian",0],
     PARAMETER["scale_factor",1],
     PARAMETER["false_easting",0],
     PARAMETER["false_northing",0],
     UNIT["metre",1,
         AUTHORITY["EPSG","9001"]],
     AXIS["X",EAST],
     AXIS["Y",NORTH],
     EXTENSION["PROJ4","+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs"],
     AUTHORITY["EPSG","3857"]]

   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
