Call PROJ4 to transform coordinates.

This subroutine calls a Fortran wrapper to the C library PROJ4. A set of input coordinates is transformed to the base SWB coordinate system.

The idea is to first create a 2D array of the X and Y coordinates in the projection system of the input data set. These coordinate values are then fed to PROJ4, which modifies the values and returns the coordinate values in the projection system of the base grid. Thereafter, mapping source to target is a matter of finding the value of the cell closest to a SWB grid coordinate pair.

Parameters

[in,out]	pGrd
[in]	sFromPROJ4
[in]	sToPROJ4

supply X and Y for the untransformed data

calculate X and Y for the untransformed data

PROJ4 expects unprojected coordinates (i.e. lat lon) to be provided in RADIANS. Therefore, we convert to radians prior to the call...

If the coordinates have been converted TO latlon, convert back to degrees
