Using GPS Technology in Land Surveying!

Oct 12th 2015 at 5:13 AM

Land surveying is one of the oldest technical practices in the world. It is believed that land surveying predates farming and even our ever expansive knowledge of plants and animals. Since its conception in ancient Egypt, land surveying has undergone a paradigm shift. Instead of the use of prisms, measuring tapes or ropes, theodolites and rulers, land surveying specialists have now resorted to using GPS technology. The change did not happen overnight. Even in 1990s, the remote and manual tools were used across the world. Today, land surveying specialists in many countries of the world are still confined to the old practices. But if you are looking for surveyors in UK, then you should ask for GPS enabled land surveying.

GPS or global positioning system as we know it is not for the sole purpose of locating a particular place or person in accordance to the latitudinal and longitudinal coordinates. It is also not confined to just measuring the distance from one place to another. GPS enabled tools can actually survey a piece of land without any manual intervention.

GPS used by land surveying specialists is a tad different from what we find in our mobiles or cars. GPS enabled land surveying tools use triangulation to demarcate the area being surveyed and accordingly documents the coordinates and the land’s features. The GPS system typically finds the coordinates and measures the distance between the coordinates based on the corresponding time of radio signals that are emitted and received using satellite backed sensors.

Surveyors in UK have readily adopted the GPS enabled systems because they are much more accurate and are also very convenient to use. Compared to erstwhile techniques used by land surveying specialists, GPS enabled systems make the entire process a cakewalk. There is no need to manually demarcate the whole area or to make complicated trilateration’s. There is no need to use prisms to measure the light reflected and the response time. One doesn’t have to involve substantial manpower or resources. The process is automated, quick and impeccably accurate. Owing to existing topographical data that is readily available, assessment of the coordinates and thus the terrain or nature of the piece of land is also made phenomenally easy.

Today, GPS enabled systems aren’t just used by private land surveying specialists but also by the governments or government agencies and various archeological institutes in the world.
