Hi all,

I just added the following section to the RFC55: http://trac.osgeo.org/mapguide/wiki/MapGuideRfc55

Addendum - New datum transformation technique in CsMap will need to be exposed in the API ¶

There is a new ticket logged against Cs-Map that fixes the 3Parameter conversion technique by introducing a new technique named "Geocentric"
http://trac.osgeo.org/csmap/ticket/4

When this defect is fixed, the switch to the Cs-Map implementation will need to have the MgCoordinateSystem API expose it via a new entry inside the MgCoordinateSystemGeodeticTransformationMethod enum
That is the only change in the API that is expected from the move to CsMap

Thanks

Hugues
