Land surveyors once used tape measures and transits to measure distances and positions. Because Take a look at the site here , electronic distance measurement, or EDM, devices have allowed for a lot more efficient and accurate measurements. These use a wave of energy that is shot between the EDM instrument and a reflector. Enough time the beam takes to come back is then calculated as distance. Today, such calculations can be achieved using sophisticated GPS systems.
The Global Positioning System uses a network of satellites to precisely pinpoint the device's location on Earth at at any time. GPS uses the principle of trilateration, utilizing the location of several satellites to pinpoint an exact location. A receiver can determine the latitude, longitude, and elevation of a point using four or even more satellites; there are always a total of 24 Global Positioning System satellites currently used. First developed by the U.S. Department of Defense as a navigational aid in 1994, today it is used in many devices, tracking from mobile phones and delivery vehicles to the movement of the tectonic plates of Earth's crust.

Exact measurement of these positions is probably the fundamental components of land surveying. The advantage of is that it is much more accurate than hand-measuring these locations. There is some degree of error in every land surveying measurements, because of human errors, environmental characteristics like variations in magnetic fields, temperature, and gravity, and instrument errors. GPS permits a lot more precise measurements than previously available to land surveyors using measuring tape and an angle sight.
Another benefit of the use of its use as a land surveyor is that the coordinates could be located precisely, while other ways of land surveying rely on measurements from other known locations, including the edge of the house line, the corner of a house, or another landmark. These locations could change as time passes, such as in case a house is torn down or another obstacle is made between your structure and the measured point; even a surveyor's stake may be removed before the land is re-surveyed. The coordinate of confirmed location on Earth, however, remains the same. Therefore, using GPS as a land surveyor produces measurements which will be accurate whatever happens to the encompassing land.
Although Global Position System receivers allow for very precise measurements, there's still a qualification of error involved. A receiver on a tripod will record the positioning slightly differently every time; when many measurements are taken, these data points will form a cluster around the actual location. Better-quality receivers, needless to say, reduce this amount of error. Survey-grade receivers, rather than those meant for non-surveying uses, may produce a group of measurements clustered in a matter of one centimeter of the specific location. Today's receivers are steadily gaining in use, but might not be as accurate because the surveyor would like, especially in areas which are heavily wooded or which have other large obstructions. However, the technology is rapidly advancing and gaining a foothold in the available equipment for land surveyors. Since 1994, the accuracy available when working with GPS units has improved steadily.
