In August 1985 Canadian Hydrographers broke new ground by being the first to use airborne laser scanning techniques to locate and survey shipping channels through parts of the Southern Route of the Northwest Passage. This survey was a landmark event in hydrographic surveying as it signaled the first time that an active airborne sensor was used for chartmaking purposes. Laser soundings were acquired in two of the highest priority areas and the processed results are being used in the compilation of a new nautical chart in the area. In 1986 the airborne team returned to this area to continue the sweep through the entire Southern Route.
