[gdal-dev] Local coordinate system and proj4

[Bryan Keith]

Hello,

I've been sent an ESRI coordinate system file (.prj) that looks like this:

PROJCS["Unknown",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Local"],PARAMETER["False_Easting",68396.30349583333],PARAMETER["False_Northing",207061.59375],PARAMETER["Scale_Factor",1.0],PARAMETER["Azimuth",0.0],PARAMETER["Longitude_Of_Center",-117.0],PARAMETER["Latitude_Of_Center",41.29],UNIT["Foot_US",0.3048006096012192]]

When I try to use this definition in proj4 using ogr tools, I get this error:

ERROR 6: No translation for Local to PROJ.4 format is known.

Is there a way to use this projection information with proj4?  ESRI ArcMap
seems to be to translate from these coordinates to lat-long WGS84.
