Oregon Lambert Projection:

PROJECTION LAMBERT /* Lambert Conformal Conic
DATUM NAD83 /* North American Datum 1983
SPHEROID GRS1980 /* Required spheroid with NAD83
UNITS 3.28084 /* International Feet, (.3048 meters)
PARAMETERS
43 00 00.000 /* 1st standard parallel
45 30 00.000 /* 2nd standard parallel
-120 30 0.000 /* central meridian
41 45 0.000 /* latitude of projection's origin
400000.00000 /* false easting (meters), (1,312,335.958 feet)
0.00000 /* false northing (meters)
