GeoPerspectives has released the most accurate and up-to-date aerial photomap of the whole of Wales. The highly detailed, full colour photography covers approximately 20,000 square kilometres at 25cm resolution. Captured using new digital camera technology, in partnership with aerial surveying company COWI, the onboard digital sensor also captured infrared imagery for identifying vegetation. In addition land elevation data has been extracted from the stereo photography allowing the creation of a three-dimensional terrain model of the whole country. (Source AGI UK)
