*True orthoimage is the one generated using the corrected by the refraction effects DSM. Orthoimages of water-covered areas generated using the DSM resulting directly by the SfM-MVS software present horizontal errors of up to 2m, depending on the real depth, since SfM-MVS depths are affected by the refraction effect.
