False Easting 6 FalseEasting false_easting Linear
False Northing 7 FalseNorthing false_northing Linear

Notes

Intergraph also includes a scale at the origin, and uses NatOriginLat/Long instead of ProjCenterLat/Long.

Results differ somewhat between PROJ.4, and PCI (GCTP) as shown in Random Issues.
