Description

PARM1

Latitude, in degrees, of the first standard parallel, usually the nothernmost.

PARM2

Latitude, in degrees, of the second standard parallel, usually the southernmost. This may be the same as PARM1 to obtain a conic with a single point of tangency.

ORG_LAT

Latitude, in degrees, of the origin of the projection.

ORG_LNG

Longitude, in degrees, of the origin of the projection.

MAP_SCL

Used only when defining a coordinate system that is to produce measurements on a scaled paper map. This value is the scale of the map, e.g. 100,000. Normally, this value is set to 1.0.

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.
