OSSIM doesn't support GEOS projection (but GDAL does)
Mantis Issue 701, reported by gpasero, assigned to ghost, created: 2013-04-16
The GEOS projection (a.k.a. geostationary projection) is not supported by OSSIM. There is no epsg code attached to this projection, but it is defined by a Proj4 string : "+proj=geos +h=35785831.0" . The OGRSpatialReference from GDAL is able to translate this string into a WKT. But the otb::GenericRSTransform is unable to instanciate a transform with this WKT.
When using projections without epsg, OSSIM has its own table to find the correct type (see Utilities/otbossimplugins/gdal/ossimOgcWktTranslator.cpp line 665).
The corresponding WKT is :
PROJCS["Geostationary_Satellite",
GEOGCS["GCS_WGS_1984",
DATUM["D_unknown",
SPHEROID["WGS84",6378137,298.257223563]],
PRIMEM["Greenwich",0],
UNIT["Degree",0.017453292519943295]],
PROJECTION["Geostationary_Satellite"],
PARAMETER["central_meridian",0],
PARAMETER["satellite_height",35785831],
PARAMETER["false_easting",0],
PARAMETER["false_northing",0],
UNIT["Meter",1]]
