A GPX file's main components include waypoints, routes, and tracks: A waypoint (wptType) consists of the WGS 84 (GPS) coordinates of a point and possibly other descriptive information. A route (rteType) is an ordered list of routepoints (or waypoints representing a series of significant turn or stage points) leading to a destination. [3]
[1] [2] ARINC 424 specifies a 132-byte fixed-length record format. Each record consists of one piece of navigation information such as an airport, heliport, runway, waypoints, navaids, airways, arrival routes, and departure routes. [3]
Wikiloc is a website, launched in 2006, [2] [3] [4] containing GPS trails and waypoints that members have uploaded. [3] This mashup shows the routes in frames showing Google Maps (with the possibility to show the layers of World Relief Map (maps-for-free.com), OpenStreetMap, the related OpenCycleMap, USGS Imagery Topo Base Map and USGS Topo Base Map).
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
The restricted random waypoint models the trajectory of a mobile user in a connected domain .Given a sequence of locations ,,... in , called waypoints, the trajectory of the mobile is defined by traveling from one waypoint to the next + along the shortest path in between them.
Waypoints may be a simple named point in space or may be associated with existing navigational aids, intersections, or fixes. A waypoint is most often used to indicate a change in direction, speed, or altitude along the desired path. Aviation RNAV procedures make use of both fly-over and fly-by waypoints. A fly-over waypoint is a waypoint that ...
DAFIF diagram of Ottawa International Airport. The Digital Aeronautical Flight Information File or DAFIF (/ ˈ d eɪ f ɪ f /) is a comprehensive database of up-to-date aeronautical data, including information on airports, airways, airspaces, navigation data, and other facts relevant to flying in the entire world, managed by the National Geospatial-Intelligence Agency (NGA) of the United States.
OpenStreetMap (abbreviated OSM) is a free, open map database updated and maintained by a community of volunteers via open collaboration. [4] Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources.
