Generating True Orthoimages without a 3 D Surface Model

  title={Generating True Orthoimages without a 3 D Surface Model},
  author={Joerg Albertz and Bert Wolf},
It is the traditional procedure to generate orthophotos from aerial photographs by differential rectification. The effects of relief displacement are corrected by considering a Digital Terrain Model (DTM). Due to the fact that DTM's do not describe the surface of buildings, bridges, trees etc. such objects remain in perspective views in the resulting orthophotos. If a Digital Surface Model (DSM) describes the mentioned objects, the caused displacements can also be corrected, and the results are… CONTINUE READING
