摘要

The era of commercial high-resolution satellite imaging commenced in September 1999 with the launch of Ikonos-2. Imaging satellites with a ground resolution of 1m provide the photogrammetric and remote sensing communities with a significant new means for geospatial information collection. This paper discusses the metric exploitation of 1m satellite imagery, and specifically looks at the options available for multi-image restitution in situations where optimal ground point triangulation accuracy is sought. Such applications would include automated DTM generation and high-accuracy feature extraction for both mapping and geopositioning. The paper commences with a discussion of a fundamental model for orientation/triangulation of line scanner imagery. Alternative restitution models, which may be applicable in instances where sensor calibration and satellite ephemeris data are unavailable to the user wishing to perform stereo or multi-image triangulation of 1m satellite imagery, are then reviewed.
