[gdal-dev] GDAL rejecting Winkel Tripel projection

[William Kyngesburye]

So, why?  Is it because it has no defined inverse projection?  I think aitoff is another such, and it's not handled by GDAL either.

I see a +wktext option mentioned in ogr_srs_proj4.cpp:importFromProj4(), but it doesn't help.  I guess importFromProj4() looks at the projection and rejects the proj4 string before +wktext is helpful.

If I could figure out a WKT definition, does GDAL restrict that?

Any other way I can get GDAL to use wintri?

Cheating, murdering, lying, fighting, and all for things that the beasts of the jungle would not deign to possess - money to purchase the effeminate pleasures of weaklings.  And yet withal bound down by silly customs that make them slaves to their unhappy lot while firm in the belief that they be the lords of creation enjoying the only real pleasures of existence....
