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]
ARINC 424 or ARINC 424 Navigation System Data Base Standard is an international standard file format for aircraft navigation data maintained by Airlines Electronic Engineering Committee and published by Aeronautical Radio, Inc.
KML files are very often distributed as KMZ files, which are zipped KML files with a .kmz extension. The contents of a KMZ file are a single root KML document and optionally any overlays, images, icons, and COLLADA 3D models referenced in the KML including network-linked KML files. The root KML document by convention is a file named "doc.kml ...
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.
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).

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.
For example, to find the midpoint of the path, substitute σ = 1 ⁄ 2 (σ 01 + σ 02); alternatively to find the point a distance d from the starting point, take σ = σ 01 + d/R. Likewise, the vertex, the point on the great circle with greatest latitude, is found by substituting σ = + 1 ⁄ 2 π. It may be convenient to parameterize the ...
