Geographic Data Files

Geographic Data Files (GDF) is an <a href="/facts/Data_exchange/sRJxD46S">interchange</a> <a href="/facts/File_format/qrXbwJaH">file format</a> for <a href="/facts/Geographic_data/FUSjSQ71">geographic data</a>.
In contrast with generic <a href="/facts/GIS_file_format/nfG1rVIP">GIS formats</a>, GDF provides detailed rules for data capture and representation, and an extensive catalog of standard features, attributes and relationships. The most recent extension expanded applicability further towards pedestrian <a href="/facts/Navigation/sGGAJ0AQ">navigation</a>, 3-D map rendering, and <a href="/facts/Advanced_driver-assistance_systems/8l0vVnKd">advanced driver-assistance systems</a> (ADAS).
GDF is commonly used for data interchange in many industries such as <a href="/facts/Automotive_navigation_system/WKCh5wt8">automotive navigation systems</a>, <a href="/facts/Fleet_management/Cd1up05G">fleet management</a>, dispatch management, <a href="/facts/Road_traffic_analysis/uxRYw4EH">road traffic analysis</a>, traffic management, and <a href="/facts/Automatic_vehicle_location/vdCICQ0b">automatic vehicle location</a>.
Originated as a flat <a href="/facts/Plain-text/TSlSSAg2">plain-text</a> file, GDF is not intended to be used directly for any large scale geographic application and normally requires conversion into a more efficient format. Consumability has been increased with most-recent developments for XML and SQL renditions.
The maps in GDF format are provided by many map vendors such as <a href="/facts/Here_(company)/dWf1qY0S">HERE</a>, <a href="/facts/TomTom/KBAVAsxg">TomTom</a>, <a href="/facts/Mapscape_BV/7EPXdygD">Mapscape BV</a>, <a href="/facts/GeoSmart/ATSoFQzX">GeoSmart</a>, <a href="/facts/Automotive_Navigation_Data/NMnoEvAP">Automotive Navigation Data</a>, <a href="/facts/AutoNavi/I0CLcea6">AutoNavi</a> and NavInfo.
