Photogrammetric flight of the National Geographic Institute Year 1980-1985

Photogrammetric flight Scale 1:30,000 made by the National Geographic Institute in 1985. It is a photogrammetric flight available to the Autonomous Community of Aragon but incomplete. These images are likely to be used in numerous projects such as the preparation of a Crop Map and harvests of that time, study of the evolution of erosion or land uses, development of infrastructure or urban areas.
