CONCEPTUAL APPROACH FOR ELECTRONIC TERRAIN OBSTACLE DATA PROVISION FOR SUDAN AIRPORTS

The Electronic Terrain Obstacle Data (eTOD) is required to develop terrain and obstacles data to support the ICAO Communications, Navigation, and Surveillance (CNS), air traffic management systems, and safety of conducting airport services. The eTOD datasets, are to provide the pilots with reliable information in their decision-making process, concerning terrain or obstacle hazards. eTOD can be used for Aeronautical Information Management and services, development, and ground-based applications. The Electronic Terrain Obstacle Data will be required for the Sudan Civil Aviation Authority(SCAA) to achieve ICAO eTOD compliance for its airports and to develop the Aeronautical Information Management (AIM) in Sudan. Aeronautical surveying is a highly specialized type of surveying, in which aeronautical survey provides critical information about airport features, obstructions, and navigational aids. This data is needed for safe aircraft operation and airport safety services. Airport surveying needs extensive knowledge of ICAO documents related to aerodromes and their environs concerning the operational areas, obstacle limitation surfaces, navigational facilities, etc. The data collection methodology by using relevant and reliable means and technologies to achieve Annex 15 ICAO requirements will be described, including terrestrial, photogrammetric, Lidar, Drone, and Satellite imagery measurements.
