Orthophoto. Year 2008

Orthophotos 40 cm/pixel. Made from two high flights (analog flight 1:18,000 and digital flight GSD 35 cm/pixel). Reference System ITRF93, Elipsoide WGS84, REGCAN95 Geodesic Network (version 2001), UTM Husso 28 projection system and altitudes referring to the average sea level determined on each island. Storage format: ECW. Orthophotography is a geometrically corrected aerial photograph (ortorectified). Unlike an aerial image, an orthophoto can be used to make real measurements since it is an accurate representation of the earth’s surface, in which the distortions inherent in aerial images have been corrected. Orthophotos combine the detail and temporal coverage characteristics of aerial photographs and the uniform scale and geometric accuracy of the maps. Dates: High flight (084, 1:18,000 and GSD 35 cm/pixel). 14/11/2007 to 19/01/2008 High flight (130, GSD 35 cm/pixel). 09/11/2008 to 26/12/2008
