Abstract
There is a growing interest in the potential of synthetic aperture radar (SAR) for mapping and for gathering intelligence for map revision. This paper first gives a simple guide to the characteristics of SAR and then describes a study carried out to investigate the geometric properties of the imagery and the information content which is of interest for topographic mapping and the production of large scale plans. The conclusions cautiously indicate a potential although better quality images are required and more information must be known about the optimum conditions which should obtain when the data are recorded.
Resume
On assiste a un interet croissant envers le radar a ouverture synthetique (SAR) et ses possibilityes pour la cartographie et pour la collecte de renseignements utiles a la revision. Ce texte commence par donner un simple rappel des caracteristiques de ces radars pour decrire ensuite une etude effectuee sur le contenu informatif et les proprietyes geometriques de l'imagerie radar, qui interesse la cartographie topographique et la confection de plans a grande echelle.
Les conclusions font prudemment etat d'une potentialite mais soulignent qu'il faudrait disposer d'images de meilleure qualitye et avoir davantage d'informations sur les conditions optimales a respecter lors de l'enregistrement des donnees.
Zusammenfassung
Es besteht zunehmendes Interesse an den Moglichkeiten von Radaraufnahmen mittels synthetischer Apertur (SAR) zur Kartenherstellung und Erfassung von Daten zur Laufendhaltung. Zunachst wird im Artikel eine einfache Einfuhrung in die SAR-Charakteristika gegeben. Dann erfolgt eine Beschreibung eines Versuches zur Untersuchung der geometrischen Eigenschaften und des Informationsgehalts, der von Interesse fur die Herstellung topographischer und grossmassstabiger Karten ist. Vorsichtige Schlussfolgerungen ergeben Moglichkeiten zur Verwendung solcher Informationen, wobeijedoch eine bessere Bildqualitat zu fordern ist. Auch mussen noch mehr Kenntnisse uber die optimalen Bedingungen bezuglich der Datenregistrierung bestehen.
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
