Land surveyors, construction professionals, geomatics engineers and civil engineers using total station, GPS, 3D scanners, and other collector data use land surveying software to increase efficiency, accuracy, and productivity. Land Surveying Software is a staple of contemporary land surveying. [13]
The most popular way to achieve real-time, low-cost signal transmission is to use a radio modem, typically in the UHF Band. In most countries, certain frequencies are allocated specifically for RTK purposes. Most land-survey equipment has a built-in UHF-band radio modem as a standard option. RTK provides accuracy enhancements up to about 20 km ...
Geopositioning can be referred to both global positioning and outdoor positioning, using for example GPS, and to indoor positioning, for all the situations where satellite GPS is not a viable option and the localization process has to happen indoors. For indoor positioning, tracking and localization there are many technologies that can be used ...
Land surveys. These detail the boundaries of a parcel of land. Topographic surveys. These illustrate the plane and elevation of the land. They’re often required for site work such as road ...
Surveying — Survey-Grade GNSS receivers can be used to position survey markers, buildings, and road construction. [6] These units use the signal from both the L1 and L2 GPS frequencies. Even though the L2 code data are encrypted, the signal's carrier wave enables correction of some ionospheric errors.
Robotics: self-navigating, autonomous robots using GPS sensors, [130] which calculate latitude, longitude, time, speed, and heading. Sport: used in football and rugby for the control and analysis of the training load. [131] Surveying: surveyors use absolute locations to make maps and determine property boundaries.
Position resection and intersection are methods for determining an unknown geographic position (position finding) by measuring angles with respect to known positions.In resection, the one point with unknown coordinates is occupied and sightings are taken to the known points; in intersection, the two points with known coordinates are occupied and sightings are taken to the unknown point.
[5] [6] The first peer-reviewed publications on using computers to help in the cartographic process predate the introduction of full GIS by several years. [7] Computer cartography is employed to facilitate a variety of computer applications, often through integration with the Global Positioning System (GPS) satellite network.
