Via our partner site at LiDAR Magazine… In FY 2007, the FAA issued three Advisory Circulars to provide guidance for the collection and submission of aeronautical data and to identify the FAA’s GIS data model for airport-related data.
The main goal of the Advisory Circulars was to develop satellite-based approach procedures and to better utilize and manage the National Airspace System. This will use GIS data to create electronic Airport Layout Plan (eALP) for airports.
The FAA requires a full spectrum of information of airports because there is so much required to operate an airport and the bigger the airport the harder it is to operate. Detailed information is required for every aspect of an airport from but not limited to the taxiways, runways, traffic lanes for service vehicles, buildings, terminals, and all the signs and assets associated them.
