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. In the restricted setting, the waypoints are restricted to fall within one of a finite set of subdomains A i ⊂ A {\displaystyle A_{i}\subset A} .
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 ]
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.
Historically, aircraft navigation specifications have been specified directly in terms of sensors (navigation beacons and/or waypoints).A navigation specification that includes an additional requirement for on-board navigation performance monitoring and alerting is referred to as a required navigation performance (RNP) specification.
A walking route with a number of waypoints marked. A waypoint is a point or place on a route or line of travel, a stopping point, an intermediate point, or point at which course is changed, [1] [2] the first use of the term tracing to 1880. [2]
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.
The airport opened on October 1, 1928, dubbed the Newark Metropolitan Airport. [16] It was the first major airport to serve the New York metropolitan area, [17] the first commercial airport in the United States and the first with a paved airstrip. [18] The first lease for space at Newark Airport was signed by Canadian Colonial Airways in April ...
