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.
Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer.
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).
The actual shapefile relates specifically to the .shp file, but alone is incomplete for distribution as the other supporting files are required. In line with the ESRI Shapefile Technical Description , [ 1 ] legacy GIS software may expect that the filename prefix be limited to eight characters to conform to the DOS 8.3 filename convention ...
A notable example is the worldwide use, in orienteering sports, of waypoints with a map that omits a coordinate system, known as control points. [ 4 ] In aerial celestial navigation, waypoints are precomputed along an aircraft's great circle route to divide the flight into rhumb lines and allow celestial fixes to be more rapidly taken using the ...
A simple diagram showing the main difference between traditional navigation and RNAV methods. Area navigation (RNAV, usually pronounced as / ˈ ɑːr n æ v / "ar-nav") is a method of instrument flight rules (IFR) navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigate directly to and from the beacons.
