Survey Control Information

SNB is responsible for the maintenance of the Provincial survey control grid for New Brunswick. A control survey network for the province, consisting of over 24,500 monuments, is maintained by SNB. The system, with its fully automated database, is supported by electronic imaging technologies. The Corporation is implementing a network based on Global Positioning Systems (GPS). Migration to the GPS survey control framework will be completed in 1998.
