LM-WCCS: Lambert Conformal Conic Projection, Wisconsin County Variation

This is a minor variation to the traditional Two Standard Parallel projection version. It supports the Wisconsin County Coordinate System group of coordinate systems. This variation uses a parallel ellipsoid technique to adjust horizontal coordinates for average elevation of the region being mapped.

Parameter Name	Description
PARM1	Latitude, in degrees, of the first standard parallel (usually the northernmost). For this projection, there is no distinction between the northern (PARM1) and southern (PARM2) standard parallels; that is, they can be switched with no effect.
PARM2	Latitude, in degrees, of the second standard parallel (usually the southernmost). This parameter is sometimes set to the same value as PARM1 to obtain a conic with a single point of tangency, that is, a single standard parallel.
PARM3	Average geoid separation in metres of the region being mapped.
PARM4	Average elevation above the geoid (that is orthometric height) in system units of the region being mapped.
ORG_LNG	The longitude, in degrees, of the origin of the projection.
ORG_LAT	The latitude, in degrees, of the origin of the projection.
X_OFF	The false easting to be applied to all X coordinates, usually selected to cause all X coordinates within the coordinate system to be positive values of reasonable size.
Y_OFF	The false northing to be applied to all Y coordinates.
