GPS Visualizer maps can now build on-the-fly elevation profiles, if the tracks contain elevation data. New DEM (digital elevation model) files from Europe have been installed on GPS Visualizer's server, thanks to OpenDataPortal. The profile utility can now draw filled "mountain range" profiles, in addition to lines also, colorized SVG profiles can use gradients for smoother and more accurate color. The ASTER DEM files on GPS Visualizer's server have been upgraded to ASTER version 3, which was released in 2019. Freemap.sk (styled OpenStreetMap data with shading and contour lines) is now available as a background option in GPS Visualizer's Google & Leaflet Maps. Location History and Semantic Location History JSON files from Google Takeout are now supported by GPS Visualizer. CSV export files from 's Connected Car Assistant device and smartphone app can now be converted or mapped with GPS Visualizer. You can now draw an in in-map elevation profile of a single track, using an icon in the track's info window. Leaflet and Google maps created by GPS Visualizer can now display ski trails from OpenSnowMap as a background map option. More 30m-resolution DEM elevation data has been installed on GPS Visualizer's server: new LIDAR-based files ("ODP1") for Iceland, and NASA SRTM1 data for Central America, the Caribbean, and northern Queensland. When tickmarks are added to a Google or Leaflet map, the "description" field of the tickmark will now contain the distance (for time-based tickmarks) or time (for normal distance tickmarks), if your input file contains the relevant data. If you create a Google or Leaflet map where the markers are displayed in folders in the marker list, you can use the gv_options.marker_list_options.folder_zoom parameter to automatically include a "zoom to contents" link next to the name of the folder. GPS Visualizer is based in Portland, Oregon, and has been on the Web since October 2002. xlsx),Īnd of course tab-delimited or comma-separated text. Garmin MapSource/ BaseCamp/ HomePort (.gdb), GPX (a standard format used with many devices and programs, including Garmin's eTrex, GPSMAP, Oregon, Dakota, Colorado, & Nüvi series), GPS Visualizer can read data files from many different sources, including but not limited to: Or, you could send an Amazon wish list item.

Gun Shot Detection monitors events in real-time using both the gun shot GPS coordinates and XProtect camera coordinates.GPS Visualizer is a free service and hopefully always will be however, if you find it interesting, time-saving, or just plain fun, you can say "thanks" - and encourage further development - by clicking the button above and making a contribution via credit card or PayPal. GPS integrates with programs such as Motion Detection, Perimeter & Intrusion and Gun Shot Detection programs. GPS is also now used in wildlife tracking and protection, providing automated collection of thousands of point locations to more precisely define home ranges and migration routes. It also supports safety for people and possessions, route optimization and reducing vehicle fuel costs. GPS systems are used for navigation on sea, land and air. Typically, the fastest reporting interval is ten seconds. To save energy, real-time GPS trackers do not send a stream of data but report positions at pre-determined intervals. The latest stage of accuracy enhancement uses the L5 band and has an ability to pinpoint to within 30 centimeters. The system operates independently from telephone or internet reception and requires only a GPS receiver. Using the mathematical principle called trilateration, GPS offers the ability to locate and track a subject, pinpointing longitude, latitude, ground speed and course of direction. Satellite signals travel at the speed of light. The satellites have atomic clocks on board and the GPS system must make allowances for Special Relativity to ensure accurate time. Their routes are mapped so that anywhere on Earth, at any time there are at least four satellites "visible" in the sky. The GPS tracking system uses 24 solar powered satellites (with six spares,) that continuously orbit earth along six different paths, traveling at an altitude of 20,000 km.
