    Hello,

    I have 3 different Digital Elevation Models and GCPs of the same area and I want to assess the accuracy of each DEM based on those GCPs. I want to know the tools that I have to use to do so in ENVI 5.3.

    I have also a question about how to generate a DEM from stereo images.

    Thank you,

    Jenny Bloom

    Have you gone through the RPC Orthorectification tutorial? I think it will highlights some tools ENVI has that are helpful to you. Here’s a link:

    On how to generate a DEM from stereo images, do you have the DEM Extraction module? This module is used to create a DEM from stereo imagery. Here’s a link:
