Equidistant_Cylindrical and Plate_Carree in morphToESRI()

[rprinceley]

Both Equidistant_Cylindrical and Plate_Carree are set to SRS_PT_EQUIRECTANGULAR in apszProjMapping table. This is causing incorrect mapping of projection names when using morphToESRI().

Robin,

My understanding is that Plate Carree and Equidistant Cylindrical are both names for the same (non) projection Equirectangular.

Is the problem that rounding tripping from ESRI to OGR to ESRI WKT is mapping Plate_Carree to Equidistant_Cylindrical?

Frank,

Yes, the round trip changes projection name - user selects a named PE projection from a list but ends up with a different name when reading exported dataset. We need to preserve "Plate_Carree" string since it is a PE projection name.

I think that this ticket points to /trunk/gdal/ogr/ogr_srs_esri.cpp. I can read that now there stands beginning from line 63:

static const char *apszProjMapping[] = {
    "Albers", SRS_PT_ALBERS_CONIC_EQUAL_AREA,
    "Cassini", SRS_PT_CASSINI_SOLDNER,
    "Equidistant_Cylindrical", SRS_PT_EQUIRECTANGULAR,
    "Plate_Carree", SRS_PT_EQUIRECTANGULAR,

But who knows what should be fixed and how?
