[gdal-dev] GetProjectionRef returns ' '

[Francois Maass]

Hello everyone!

 

I have as input, two satellite images, one in .pix format and the other in
.TIF format. 
I am trying to do projections between these two images, and have a function
which contains the following:

 

if( gdalDataset->GetProjectionRef
<http://www.gdal.org/classGDALDataset.html#a42537e1062ce254d124b29ff3ebe857>
()  != NULL )
        printf( "Projection is `%s'\n", gdalDataset->GetProjectionRef
<http://www.gdal.org/classGDALDataset.html#a42537e1062ce254d124b29ff3ebe857>
() );

 

 

When I call this function with the .pix image as parameter, I get the entire
projection definition string, but when I pass the .TIF image as parameter, I
get "Projection is ' '".

Can anyone tell me why this happens?

 

Thank you for your time!

Francois
