Sayyed Mohammad Javad Mirzadeh

Dear Dr. Dehnavi,

About DEM extraction from stereo images, I recommend you to use the PCI software because in this software, you can easily define the RPCs files for DEM extraction module.

Best regards

Vladimir Skripachev

Hi,

What kind of Camera Model do you have ?

I guess that you have Pushbroom Sensor.

What parameters values do you enter to ENVI ?

with regards

Sahar Dehnavi

Thank you very much for all your comments and guidelines.

Mohammad: I will test the PCI also on my image data. Hope it will work. Thanks for your suggestion a lot.

Ali: Thank you very much for the Pdf file that you sent for the orthorectification. It was very nice, but unfortunately I did not find any information about an approach for introducing my RPC file!! Do you have any idea for that? I would be thankful if you could kindly let me know.

Valdimir: You are completely right. I have a Pushbroom camera model. I should enter Interior Orientation Parameters and introduce some GCPs on images since I have no GCP available in my test area. Please do not hesitate to let me know if any further information was required.

Thanks again for all.

Best,

The solution was to define a RPC file which was based on some GCP points and Rational Function Model (RFM).

I used a function for generating RPC files.

The RPC information which was added to the header file of my image in ENVI was not very useful for me :)

best,

Sahar
