Comment (by wonder):
Indeed it looks to be OGR problem as Markus suggested. From my tests - the
proj4 string for this projection (epsg 26745) is:
{{{
+proj=lcc +lat_1=35.46666666666667 +lat_2=34.03333333333333 +lat_0=33.5
+lon_0=-118 +x_0=609601.2192024384 +y_0=0 +ellps=clrk66 +datum=NAD27
+to_meter=0.3048006096012192 +no_defs
}}}
When you import it to OGR and export as WKT, you'll get:
{{{
PROJCS["unnamed",
GEOGCS["NAD27",
DATUM["North_American_Datum_1927",
SPHEROID["Clarke
1866",6378206.4,294.978698213898,AUTHORITY["EPSG","7008"]],
TOWGS84[-3,142,183,0,0,0,0],
AUTHORITY["EPSG","6267"]],
PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],
UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9108"]],
AUTHORITY["EPSG","4267"]],
PROJECTION["Lambert_Conformal_Conic_2SP"],
PARAMETER["standard_parallel_1",35.46666666666667],
PARAMETER["standard_parallel_2",34.03333333333333],
PARAMETER["latitude_of_origin",33.5],
PARAMETER["central_meridian",-118],
PARAMETER["false_easting",2000000],
PARAMETER["false_northing",0],
UNIT["unknown",0.3048006096012192]]
}}}
You can see that the units are set to unknown and not feet.
Probably this could be fixed in OGR... Frank?
