I don't know the reason.

You can write the WKT and add a EXTENSION['PROJ4','+proj=wintri ...'] node in it, so it is used when translating it into proj4. > > On Oct 22, 2010, at 3:07 PM, Even Rouault wrote: > > apparently, the OGRSpatialReference object has currently no support for > > this projection. > > > > Le vendredi 22 octobre 2010 21:50:59, William Kyngesburye a écrit : > >> Using gdalwarp and ogr2ogr with: > >> > >> -t_srs '+proj=wintri' > >> > >> I get: > >> > >> Translating source or target SRS failed: > >> +proj=wintri > >> > >> and: > >> > >> Failed to process SRS definition: +proj=wintri > >> > >> respectively. > >> > >> Other proj-style SRS definitions work, but not wintri.
