Abstract
This paper describes some experimental investigations into the variation of digital terrain model (DTM) accuracy with sampling interval, based on data acquired using stereophotogrammetric methods. The main factors affecting DTM accuracy are reviewed and various alternative schemes for carrying out experimental tests on DTM accuracy are outlined. Detailed information is given about the test areas, source data sets and check point data sets, followed by a discussion concerning the special design of this experiment. The experimental results are reported and, finally, a critical analysis of the test results is presented.

Zusammenfassung
Im Artikel werden einige experimentelle Untersuchungen zur Variation der Genauigkeit von Digitalen Gelandemodellen (DTM) beschrieben, wobei ein Rasterintervall verwendet wurde, das auf stereophotogrammetrischer Datenerfassung basierte. Es werden die Haupteinfluβfaktoren auf die Genauigkeit der DTM betrachtet und verschiedene alternative Wege zur Testung der DTM-Genauigkeit skizziert. Detaillierte Angaben erfolgen zu den Testgebieten, den Quelldaten-Satzen und den Datensatzen der Kontrollpunkte mit anschlieβenden Ausfuhrungen zur speziellen Gestaltung dieses Versuchs. Die Versuchsergebnisse werden angegeben, und abschlieβend erfolgt ihre kritische Analyse.
期刊介绍:
The Photogrammetric Record is an international journal containing original, independently and rapidly refereed articles that reflect modern advancements in photogrammetry, 3D imaging, computer vision, and other related non-contact fields. All aspects of the measurement workflow are relevant, from sensor characterisation and modelling, data acquisition, processing algorithms and product generation, to novel applications. The journal provides a record of new research which will contribute both to the advancement of photogrammetric knowledge and to the application of techniques in novel ways. It also seeks to stimulate debate though correspondence, and carries reviews of recent literature from the wider geomatics discipline.
Relevant topics include, but are not restricted to:
- Photogrammetric sensor calibration and characterisation
- Laser scanning (lidar)
- Image and 3D sensor technology (e.g. range cameras, natural user interface systems)
- Photogrammetric aspects of image processing (e.g. radiometric methods, feature extraction, image matching and scene classification)
- Mobile mapping and unmanned vehicular systems (UVS; UAVs)
- Registration and orientation
- Data fusion and integration of 3D and 2D datasets
- Point cloud processing
- 3D modelling and reconstruction
- Algorithms and novel software
- Visualisation and virtual reality
- Terrain/object modelling and photogrammetric product generation
- Geometric sensor models
- Databases and structures for imaging and 3D modelling
- Standards and best practice for data acquisition and storage
- Change detection and monitoring, and sequence analysis
