Salut Manuel, Thanks for the fast reply. Concerning the two problems:
1. I computed both TOA and TOC. TOA already has a maximum reflectance value of 1.0 for some bands. This would mean 100% reflected light, which seems to be a wrong value to me. So the problem can not be related to TOA to TOC conversion. However, when comparing TOA and TOC, the maximum TOC reflectance for the different bands of a WV2 scene is sometimes larger and sometimes smaller than TOA. I can not explain this. I assume, that when computing the TOC using the 'OpticalCalibration' application, TOA will be computed internally automatically and input will therefore be the same original image as when computing TOA (this is not completely clear in the documentation). 2. As stated in the posts above by 'dcd' the bandID 'MS1' in the WV2 IMD file is not accepted when running the 'OpticalCalibration' application. It still must be manually changed to 'Multi' in the IMD file to make the application work. The above posts state that this issue was corrected already one year ago. I use OTB in version 3.20.0. I also had a quick look to the SMAC website you've linked. It seems that these SMAC coefficient do not support several of the very common VHR sensors like WV2. Hope OTB will still fully support these sensors in the future, there is no real alternative in open source for these...
