[gdal-dev] Coordinate Transformation Question

[Joel Odom]

Is it possible to transform between a Lambert projection (NAD83 datum)
and WGS84 geographic?  I'm trying the following, but poCT is null:

OGRSpatialReference oSRS;
if (oSRS.importFromWkt((char**)&projectionRef) != OGRERR_NONE)
  //...
OGRSpatialReference wgs84;
wgs84.SetWellKnownGeogCS("WGS84");
OGRCoordinateTransformation *poCT =
OGRCreateCoordinateTransformation(&oSRS, &wgs84);


In this case oSRS is the Lambert Conformal / NAD83.  Thanks for any help.
