In order to plan and manage wireless networks, data on terrain height, tree height, building height and mutual dislocation (for urban areas) are necessary. Wireless networks, such as mobile communication towers and broadcasting antennas, require direct visibility between broadcasting equipment.
In order to ensure best choice of tower location and modelling signal broadcasting, digital surface models are used by involving data from surface laser scanning.
Metrum owns an aircraft equipped with laser scanner for land surface scanning. Data processing is performed by specific software, establishing surface models and modelling broadcasting areas.
