1st, I have been doing a bunch of orthorectifications today with 11 Worldview 2 scenes (M1BS variety) and with each consecutive run of RPC Orthorectification Workflow with different, but perhaps adjacent images and the same DEM, the updated GMTED2010 layer, I have noticed that the Geoid Correction value is increasing. Is it just me and my situation, or is there a possibility that the geoid correction value can accumulate over successive runs of that workflow? The value is calculated automatically says help, but why should it climb? 2nd, the RPC Orthorectification report never produces a file; and an error is generated saying that the file cannot be written because it is already in use. The output orthorectification is produced but not the text file. What's happening here, please? Thanks. Peter

I have not experienced the first issue you mention. Are you performing these orthorectifications in the interface or using the API? I would not be surprised that the geoid correction changes for each image but it shouldn't increase by the number of images. I would be very suspect if I used the same image in succession and the geoid correction changed. For the second issue, I was able to reproduce this. It was surprising that I have not heard others report it but perhaps this output isn't requested very often. I was able to test it in ENVI 5.3 (due for release this August) and the error was not present in that version so it appears to be 'fixed' and no longer giving an error.
