GPS drawing. GPS drawing, also known as GPS art, is a method of drawing where an artist uses a Global Positioning System (GPS) device and follows a pre-planned route to create a large-scale picture or pattern. The .GPX data file recorded during the drawing process is then visualised, usually overlaying it as a line on a map of the area.
Computer cartography (also called digital cartography) is the art, science, and technology of making and using maps with a computer. [1][2][3] This technology represents a paradigm shift in how maps are produced, but is still fundamentally a subset of traditional cartography. [3][4] The primary function of this technology is to produce maps ...
The Global Positioning System (GPS), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. [3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the ...
A geotagged photograph is a photograph which is associated with a geographic position by geotagging. Usually this is done by assigning at least a latitude and longitude to the image, and optionally elevation, compass bearing and other fields may also be included. In theory, every part of a picture can be tied to a geographic location, but in ...
A local positioning system (LPS) is a navigation system that provides location information in all weather, anywhere within the coverage of the network, where there is an unobstructed line of sight to three or more signaling beacons of which the exact position on Earth is known. [2][3][4][5] Unlike GPS or other global navigation satellite ...
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [1][2] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [1] In a broader sense, one may consider such a system ...
OpenStreetMap (abbreviated OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and also import from other freely licensed geodata sources.
A GPS receiver processes the GPS signals received on its antenna to determine position, velocity and/or timing. The signal at antenna is amplified, down converted to baseband or intermediate frequency, filtered (to remove frequencies outside the intended frequency range for the digital signal that would alias into it) and digitalized; these ...
