Federal 3-D Densification Network
Description
The Federal 3-D Densification Network consists of (approximately 2000) monumented stations, positioned three-dimensionally with GPS to centimetre-level accuracy with respect to the Canadian Active Control Systems (CACS). It provides the link between the existing framework and the CACS. The network densifies 3-D control within the Canadian Base Network.
