[MetaCRS] CS-MAP patch: Repair PSTEROSL south-oriented projection

[Hugues Wisniewski]

Hi Raven,

After a quick check I'm sorry to say that available resources are fully booked for the upcoming days to be able to review this in time before the end of your cycle.

Hi Hugues,

Thank you and Andreas for committing our patch to repair the sourth-oriented PSTEROSL logic (as per http://trac.osgeo.org/csmap/ticket/162).

I've attached a patch to add support for two coordinate systems using this projection:
- WGS84.Antarctic/Stereo (EPSG:3031, WGS 84 / Antarctic Polar Stereographic)
- WGS84.Arctic/Stereo (EPSG:3995, WGS 84 / Arctic Polar Stereographic)

Namemapper.csv currently points to the first of these, WGS84.Antarctic/Stereo, but there is no corresponding definition in coordsys.asc. This patch adds one in using the existing name.

I'm not aware of an open trac ticket requesting these systems, but would be happy to file one if requested.

We are nearing the end of our release cycle; it would be helpful if you could approve or reject the patch this week.

Regards,

Paul

Hi Hugues,

We've identified that the PSTEROSL south-oriented projection code has a defect. The calculations to compute the scale factor based on a latitude of true scale only work for the north-oriented variant.

Could you review our attached patch to repair this issue?

Regards,

Paul
