Description

PARM1-24

Use these elements to specify the power series coefficients. Odd and even number pairs, for example, PARM1 and PARM2, are used to specify the real and imaginary components of the coefficients respectively. All other PARMs which represent unused coeffi­cients must be set to zero. FME will determine the order of the series by looking for zero coefficients. Therefore, orders as high as 12 are supported. Orders higher than 12 are not supported.

ORG_LNG

The longitude, in degrees, of the origin of the projection.

ORG_LAT

The latitude, in degrees, of the origin of the projection.

SCL_RED

This element must be set to 1.0.

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, 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.
