Rapid advances in digital camera technology, real-time satellite differential global positioning systems, and digital imaging from airborne platforms have yielded new opportunities for on-the-fly, in situ digital mapping when used in conjunction with state-of-the-art digital photogrammetric workstations. Written by active participants in the promotion of airborne digital mapping systems, Digital Aerial Survey: Theory and Practice is a comprehensive manual that examines the systems available for data capture and photogrammetric processing. Starting from first principles it develops a solid foundation in digital imaging technology and aerial survey practices. It covers the very lastest digital air cameras, critically analyzes their performance, and addresses all aspects of airborne operation, from the aircraft and GPS navigation to survey flight planning. The text includes a CD-ROM that provides Excel files that calculate mission/ photographic parameters to make the planning of an actual survey straightforward. Digital Aerial Survey: Theory and Practice provides the opportunity to appreciate, understand, and apply photo-interpretation, reconnaissance, and photomapping techniques to a variety of planning, resource harvesting, pollution prevention, civil engineering, and disaster mitigation activities.
