Professional measurement and Land surveying has been in use for centuries and is widely known as the second oldest profession humanity has ever conceived. Because humans always had the need to know exactly where they were located and accurately determine their position in the planet, surveying was created back in ancient Egypt with the use of rope extensions and the applications of uncompounded geometry. Since those times, many things have evolved making tools and other accessories easier to use and to find accurate data, specially in the always important field of land surveying.
By the 1990s, simple and almost remote tools were still used in land surveying, like tape measurements, rulers and theodolites. Uncomplicated items that helped scientists to find their three-dimensional position in the planet. But the need for more sophisticated and less time consuming tools pushed scientists and researchers around the globe to find better ways to locate themselves.
The first top of the line tools used in land surveying would contain prisms, also known as reflectors, so they could find the measurements of the lights that would return and make it possible for one to know the distancing of a determined spot. Nowadays the distancing measurements tools are fully robotic, and the locations are completely satellite automated. The GPS (Global Positioning System) is a more secure and fast way to measure a vast piece of land without having to waste so much time to determine the area you're trying to ascertain.
There are 5 Key Uses for GPS Surveying
- Determining a position (location)
- Moving from one place to another (navigation)
- Monitoring the movement of a person or object (tracking)
- Creating a map of an area (mapping)
- Making precise time measurements (timing)
The GPS tool works as a type of triangulation which does not involve any angles but is actually a trilateration, which only means that it's a method to find the positioning of some objects using simple geometry. This entire task is orchestrated by satellites. The GPS receiver will find the coordinates and measurements of the distance desired using the radio signals' traveling time. To get to a traveling time accurately, the system will use the time the signal took to reach the receiver times the speed of light and by doing so it will have the exact distance to the satellite.
This land surveying technology has changed immensely being used for a lot of different purposes than its original. The uses of GPS helped land surveying turn into more than just a profession for a few. GPS helps all types of people by giving them time and tools to help their work to get delivered faster and more accurately.
Aside from discovering the exact location of things, the GPS is also used for navigation purposes, mapping the Earth's areas and territories, tracking people and objects and to bring precisely timing into our lives.
The use of land surveying and GPS by governments is widely known. They're called cadastral land surveying and they're conducted by Federal Government surveyors and this branch of land surveying is usually needed for the re-establishing of territory and land lining.
GPS and land surveying is everywhere we look at in our lives, and those who work exhaustively for the evolution of such tools and what they can do for us don't show signs of slowing down. Thanks to this art of land surveying, the world's population will always be aware of they stand and what time it is, enabling societies and civilization as a whole to find better ways to use the land and resources the earth has provided us with.
