FME Form: 2024.1
This is a minor variation to the traditional Two Standard Parallel projection version. It supports the county coordinate systems developed by the Minnesota Department of Transportation. This variation uses a parallel ellipsoid technique – different from that used in Wisconsin – to adjust horizontal coordinates for average elevation of the mapped region.

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 elevation above the ellipsoid, in system units, of the region being mapped by this coordinate system. |
|
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. |
