[gdal-dev] geotiff projection not showing up

[Norman Goldstein]

I have created a geotiff file using the "GTiff" driver, and have successfully set options for it to be a strips file with no compression. Also, successfully called the functions

dataset->SetMetadataItem( "AREA_OR_POINT",
                                            "Point",
                                             nullptr ) )

and

dataset->SetGCPs( 3,
                               gcps,
                               "Richmond" )

Here is the listgeo dump:

 ... unable to transform points between pixel/line and PCS space

I also set the reference system using the following code:

/////////////////////// c++ code ////////////////////////////
  OGRSpatialReference oSRS;
  oSRS.SetProjCS( "NoWhere" );
  oSRS.SetWellKnownGeogCS( "WGS84" );
  oSRS.SetEquirectangular( 0.0,        // Centre lat
               0.0,        // Centre lon
               0.0,   // False Easting
               0.0 ); // False Northing

  char* wkt = nullptr;

  if( OGRERR_NONE != oSRS.exportToPrettyWkt( &wkt ) )
  {
     error...
  }

  if( CE_Failure == dataset->SetProjection( wkt ) )
  {
   error...
  }
///////////////////////////////////////////////////////////////



I am happy to upload a full working example if needed.

Thank you.

So, why is listgeo not able to transform points between pixel/line and PCS space?
