Paper Abstract

This paper proposes a geographical information system for terrain and obstacle awareness and alerting that extracts information from high-resolution satellite images. On-board terrain elevation databases are being increasingly used in aircraft terrain awareness and warning systems (TAWS), offering a step change in capability from the radar altimeter-based ground proximity warning system. However, to enhance the safety of flight of small aircraft and helicopters, in addition to pure topographic information a TAWS database should also contain significant man-made obstacles that present a collision hazard, such tall buildings and chimneys, communications masts and electrical power transmission lines. Another issue is keeping the terrain and obstacle database current, reflecting changes to features over time. High-resolution stereoscopic images remotely sensed from Earth orbit have great potential for addressing these issues. In this paper, some critical items are discussed and effective information processing schemes for extracting information relevant to flight safety from satellite images are proposed.
