- Title
DEM Generation Using a Digital Large Format Frame Camera.
- Authors
Höhle, Joachim
- Abstract
Progress in automated photogrammetric DEM generation is presented. Starting from the procedures and the performance parameters of automated photogrammetric DEM generation, the results of some practical tests with large scale images are presented. The DEMs are derived from images taken by a digital large-frame aerial camera and checked by reference data of superior accuracy. In average, a vertical accuracy of σ[subh]=13 cm or 0.20 per thousand of the mean flying height above mean terrain has been achieved. Some recent innovations in digital large-frame cameras and in the processing software give hope for even better results. In comparison with results from film-based cameras; it can be stated that both technologies are able to produce very dense and accurate DEMs.
