DEM extraction for an orthorectification of radarsat-2 image
I'm a student who is using Geomatica 2012 Orthoengine for an orthorectification of Radarsat-2 images. These are images of February, 06 2009; February, 23 2009; October, 09 2010 for Cotonou City, Benin.
I got this error "no overlap between the image and your DEM".
Can anyone help me for having a good method for DEM extraction.
Thanks in advance.
