With COWI’s investment in the latest large format digital cameras, heat-sensitive camera systems, LiDAR systems and oblique image systems, we can ensure efficient airborne data acquisition and the delivery of high quality products.

Our aircraft are on flight missions all over the world. At COWI, we have many years of experience in optimizing and adapting specifications and data structures so that digital vector maps meet our clients' present and future demands.

Mapping tasks all over the worldCOWI’s aircraft and various camera systems are used in complex mapping tasks all over the world. Recent projects are for example the aerial survey of Qatar for the Qatar National Aerial Mapping 2008, the production of a nationwide orthophoto of Serbia, Lithuania as well as 275.000 sqkm in Namibia, the laser scanning of Lithuania and Sweden, accurate digital elevation models for roads in Oman and the update and improvement of the Ordnance Survey Great Britan's (OSGB) digital map data as well as the acquisition of oblique images covering a number of cities including Doha, Munich and Gothenburg.

 

Mapping temperatures to assess cool and heat loss With the investment in a new thermal camera system COWI is ready to conduct aerial surveys to identify badly insulated offices, residential housing as well as industrial complexes. This may concern cooling as well as heating. The system can equally identify leaks and malfunctioning of water supply networks, oil pipelines and air conditioning systems. The temperature maps from the thermal survey can be used to analyse the existence and extend of the urban heat island in major cities, where the central part is being heated up. The data can be used by authorities, research and commercial companies.

Our aerial surveying is used for:

• Mapping and updating of digital maps
• Acquisition of orthophotos and oblique photos
• Laser scanning for the creation of Digital Elevation Models (DEM)
• Thermal survey to create temperature maps
