Since 1993 when Geokosmos was established in Moscow, the company has always been a pioneer in application of most advanced technologies for collection and processing of geospatial information. Focusing on innovative laser scanning and digital aerial photography technologies allowed to find more effective solutions for a number of industries.
In October 2006 Geokosmos performed the project focused on multi-purpose aerial survey of city territory using aircraft with onboard equipment complex consisting of LiDAR system ALTM 3100, large-format digital camera Vexcel UtraCam-D, and two inclined digital metric cameras Rollei AIC-modular-LS (H25). That was the first practical application of such equipment complex, demonstrating possible integration of different data collection technologies.
Such equipment combination provides the data for multi-purpose use. In addition to orthophoto imagery, digital terrain (DTM) and elevation (DEM) models there is a set of oblique images allowing creating 3D virtual models of urban territories.
The project goals, its key parameters and major results are provided. Possible application areas for the equipment complex are also described. Main focus is given to the equipment application for the purpose of urban planning and management. Implementation of the equipment complex allows increasing the productivity of the survey as well as reducing dramatically the volume of terrestrial surveying works resulting in significant money saving.
