Hi Julien, we also do orthorectification of RapidEye L1B. Currently we use the gdalwarp -rpc -to "RPC_DEM=xxx" to create the orthos using a high resolution DEM. However, we are working with time series and we need to register the images to each other at subpixel accuracy. We are trying to achive this in OTB with Extract_homologousPoints > GenerateSensoreModel > Orthorectification. However, above you mentioned that OTB directly supports rpc coefs embeded in tiff. Would it be possible to directly define the sensor model from these and then only refine the sensore model based on homologous points for the image co-registration? If yes, how can we define a sensor model based on embedded RPC coeffs?
