Dear Julien, thanks for your fast reply. The .geom file was produced or kept by OTB when applying the 'OrthoRectification' tool. I did the preprocessing workflow starting with an original WV2 scene as described in your cook book and in the following order:
1. OpticalCalibration 2. BundleToPerfectSensor 3. OrthoRectification However, when comparing the orthorectified image with the preceding pansharpened image I can see not a single pixel of shift throughout the scene. Are you sure that ortho rectification can be done in the last stage with the OTB toolset? Concerning the RefineSensorModel with manually picked GDPs a tool for manual GCP collection in Monteverdi would be very useful for any future version. Monteverdi1 already includes something similar with the HomologousPoints' menu entry but does not allow an export of the coordinate list in a format and coordinate system required by the 'RefineSensorModel' tool. So currently I have to do uncomfortable workarounds with diverse other software...
