Using GIS and Remote Sensing to Enhance Air Navigation Safety

The development of geographic information systems (GIS) and advanced remote sensing technology has greatly contributed to increasing the situational awareness of pilots. This article reviews and discusses some of those successes. Topics covered include the challenges of situational awareness; takeoff and landing challenges, including airfield survey and noise abatement; enroute challenges, including common horizontal and vertical datum, enroute navigation, and enroute terrain avoidance; and ongoing trends in GIS. The author presents one case study of the modeling of the 11 most hazardous mountain passes in Alaska for general aviation aircraft. The author describes trends in surveying, including new equipment such as laser range-finding binoculars that accelerate and decrease costs of ground survey, reduction in the cost of lidar (Light Detection and Ranging) to increase the number of airfield aerial surveys, and completion of the SRTM DTM construction. In the area of takeoff and landing, new trends include the use of moving maps and the use of multiple sensors for navigation, such as Forward-Looking-Infrared-Radar to see ahead of the aircraft in poor weather.
