Hello,
I am want to Orthorectify Hyperion images, what is the best way of doing so?
Hyperion sensor is not defined in ENVI.
Best Regards
Mustafa

Hyperion data is not supported in the Rigorous Orthorectification module and Hyperion is not distributed with RPCs which are required to perform RPC orthorectification. You would need to first use the Build RPCs tool to build RPCs for your image and then you could use the RPC Orthorectification tool.

I requested sensor parameters from USGS, I hope they may get the parameters such as focal length etc.
I expected ENVI, which is the leading tool in Hyperspectral data processing to include some parameters for Hyperion which is still active.
I found this thread for Orfeo Toolbox where you may build RPCs by only using matches: https://groups.google.com/forum/#!topic/otb-users/Mt9OhRQqGEw

Hello! I read the post and I' m sorry if I duplicate the question. I want to orthorectify my hyperion image, so I have to build RPC's first...But I don't know where I can find the needed information for this procedure?

I believe you can order Hyperion in L1T, which is terrain corrected, so it is already orthorectified. Since the sensor was decommissioned in 2017, it is unlikely we will develop any new tools for this sensor.

That was very helpful! Thank you so much...And after I can georeference my image with another one (such as an image from ASTER?)?

Yes, ASTER (1B) has spatial reference and Hyperion L1T will be terrain corrected. You can use the Image Registration workflow to coregister these two images.
