[GIS] Create DEM from cartosat stereo pairs

Question

I have two carstosat stereo pair images. All i need to do is to extract DEM from those.
So, i tried it doing with OSGeo4W. but i didn't succeeded in it.

So IS there any other softwares or opensource for extracting DEM from cartosat pair?

Thanks in advance

Answer 1

There are several softwares for doing this. Here is a non exhaustive list :

Commercial licence :

• Imagine Photogrammetry (= formerly LPS) This is very powerful but very expensive
• ENVI DEM module
• photoscan Not very expensive, but more oriented toward drone image processing, so not the best for satellite data

Open source :

• Orfeo Toolbox Not tested for photogrammetry, but the modules are there
• MicMac I've heard of it but never tested. Again, this is more for drone data and not really for satellite data. And not very easy to manipulate...
