[GRASS-user] Unable to read .prj file

[Rich Shepard]

Environment: Slackware-14.2, Grass 7.7.svn (r74061).

Trying to create a new location using a shapefile .prj. GRASS tells me it
cannot read the file using gdal. There are five mapsets I want to import and
they all have the same .prj file:

PROJCS["NAD_1983_UTM_Zone_11N",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",-117],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1]]

Do I look for the appropriate EPSG code or am I doing something incorrectly?

Advice appreciated,

Rich
