#6598 closed defect (fixed)

MapInfo TAB support doesn't create Oblique_Stereographic projections

Reported by: dougc Owned by: warmerdam
Priority: normal Milestone: 2.2.0
Component: default Version: 2.1.1
Severity: normal Keywords: mapinfo tab oblique double stereographic


In mitab_spatialref.cpp method TABFile::GetTABProjFromSpatialRef, Oblique_Stereographic projections with MapInfo ID #31, also known as double stereographic, are not handled. The resulting TAB ends up with a non-earth projection set. I've attached a patch against the 2.1.1 source to add a case for SRS_PT_OBLIQUE_STEREOGRAPHIC.

For round-trippability, shouldn't the code path on reading call SetOS() when code == 31 instead of SetStereographic() ?
