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]
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" at the root directory level, which is the file loaded upon opening. By convention the root KML ...
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 LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used [1] and regarded as an industry standard for lidar data.

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 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.
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 ...
