Moscow, Russia, 3 July 2006: Geokosmos, Moscow based air survey company, has completed a 3D mapping project using up-to-date digital technologies in Andalusia, autonomous region of Spain for various Municipal authorities.
Using the aerial laser scanning technology, Geokosmos conducted a survey of the Guadalquivir River, which is one of the longest rivers on the territory of Spain with a length of 3144 km with a rather complicated surface, aiming to create 3D Digital Terrain Model. The total volume of work reached approximately 700 sq. km. The survey was conducted with up-to-date LiDAR equipment – ALTM 3100 (produced by Optech Inc.) – and by medium format digital camera Rollei AIC modular LS.
The high precision 3D Digital Elevation Models of the river’s channel supplied to the customer allow to: forecast the potential flood locations, plan preventive measures in case of flood, conduct shore protection and create GIS for water resources management.
