Global Positioning Systems (GPS), are increasingly used, for not just control surveys, but a large proportion of land surveys in general thanks to the development by The Ordnance Survey of a network of GPS receivers around the country providing on-site positioning to Ordnance Survey mapping.
Latitude Surveys Limited can provide clients with accurate and reliable site survey control, measured using robust GPS measuring techniques and data processing software and using 4G technology can immediately provide clients on site with levels relative to Ordnance Survey height datums, which can then be used for Flood Risk Analysis.
