Automatic Surveying � Updating Canada's Control

Abstract:

With Litton's Auto-Surveyor system you can perform third-order surveys driving at highway speeds or flying in a helicopter. With proper planning you can reduce months of field work to weeks�� and have field data available immediately for comparisons, checks, and reviews. Survey control can be extended further and faster with fewer operators. Precise gyroscopes and accelerometers combine with electronics to sense and measure movement horizontally and vertically, and provide split-second position and azimuth information at the turn of a dial. Automation also applies to mapping. Canada is using all the latest technology to survey and map that vast country. Ultimately they will have a modern, tight, and dense survey control and cartographic file.
