| Summary: | In the mid-sixties the Canadian Hydrographic Service began to investigate methods of providing computer assistance to hydrographers that were using conventional data collection techniques. Navbox , a microprocessor-controlled survey aid, is a product of these investigations. It provides straight line navigation from a variety of positioning systems, and positions and depths are verified using software filters. First used on board helicopters and tracked vehicles in the Arctic, Navbox has been used on regular hydrographic surveys since 1977, and has a number of real and potential survey applications. |
