Description |
|
PARM1 |
Longitude, in degrees, of the central meridian. |
|
ORG_LAT |
Latitude, in degrees, of the origin of the projection. |
|
SCL_RED |
The scale reduction to be applied. This is also referred to as the scale of the central meridian. |
|
MAP_SCL |
The scale of the coordinate system. This one factor must include the conversion from metres to coordinate system units, and the mapping scale to be applied. This factor is ignored during computation. |
|
X_OFF |
The false easting to be applied to all X coordinates, 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. |
