Hi Cinthia,

I do not know what "orthorectify" means. Part of my work uses the
mapping routines in IDL, satellite images and DEMS, so I may be able
to help. But most of my images/datasets are regularly gridded on
lat/lon grids, which I think is why I do not know what orthorectify
means...

Are you trying to make 3D scenes by combining the images with the DEM?
Can you go into a bit more depth on your question?

Thanks,
-k.
