Hello all,

I am working on two stereo images and would like to extract a DEM from these two images. Hence, I used DEM extraction Wizard approach in ENVI, but I can not go through steps since I have a problem in the first step.

After introducing stereo pairs as inputs, software asked me to insert a file which contains RPC information.

I have no idea what is the exact file that I can introduce as input in this step!!

PS. I used the Build RPC menu in ENVI and this procedure added some extra information to the header file of my image data. But still none of the outputs from Build RPC procedure is useful to introduce as an input.

I would be very thankful if anyone can help or has any idea about this.

Thanks,

Sahar
