Moscow, Russia, July 13, 2007: Using combined airborne laser scanning and digital aerial photography technology Geokosmos surveyed that part of the railroads which connects Amiens and Bouillon and covers an area of 83 km. The captured data was used for producing of a large-scale digital topographic map (scale 1:500) and a digital orthophoto (GSD 5 cm) that will definitely help French National Railways Service to provide technical assessment of the French railways and its infrastructure.

The accuracy of captured data, aerial laser scanning combined with aerial digital photography was conducted with high density of laser points – 7 points per 1 sq. m. Planimetric and height and accuracy constituted 5 cm.
