GEOTAG VIDEO DRIVERS

Separating metadata from audio-visual content reduces access bandwidth to allow relevant media to be identified more rapidly, enables strict access control using security permissions and retains evidence integrity by preserving source data unchanged. WebVMT integrates seamlessly with existing video metadata formats such as the Motion Imagery Standards Board (MISB) and GPMF, and bridges the gap to make video location data accessible to web browser applications and search engines via HTML and JavaScript APIs. A similar approach is now in development for video geotags with the advent of Web Video Map Tracks (WebVMT) - an open format designed to synchronise location with video for the web - which is based on W3C's subtitle format ( Web Video Text Tracks) and focusses instead on geospatial metadata. Standardisation has already solved the problem of sharing video online, enabling movies to be played in modern web browsers and broadcast to a worldwide audience. In markets dominated by a profusion of proprietary formats, many users struggle to access their own data - let alone share it with others. Geotagged video is readily available but unlocking its potential is a thorny issue.

Dashcams record vehicles to ensure that drivers are safe, body-worn cameras protect workers in hazardous environments, drones reveal airborne insights into the local area and smartphones crowdsource footage around the world. The sustained popularity of smartphones has produced low-cost electronic cameras and global navigation satellite system (GNSS) receivers and spawned a generation of location-aware video devices.Ĭonsumer products offer sharp images, accurate geolocation and good reliability that provide affordable off-the-shelf solutions to private and commercial users alike. Rob Smith, AwayTeam looks at standardisation of location-aware video devices as part of techUK's #GeospatialFuture campaign week Video Nation
