Because ancient civilizations in Mesopotamia, Egypt and Rome, man has used tools to measure and preserve his boundaries and separate himself from his neighbors. When the usage of such tools had been all but lost inside the Middle Ages, the Renaissance saw a resurgence in interest and need to have in tools to survey and parcel the land around them. Numerous tools nevertheless used nowadays are equivalent to those used to map and survey the initial settlements with the Usa. We're in the dawn of a brand new era, even so, where technology which has not drastically changed in the past hundreds of years are being introduced for the pc age, which has served to only make man's estimations much more accurate than ahead of.

In its earliest forms, one on the major tools for conducting land surveys was a chain (often generally known as a Gunter's chain) of a precise length. These chains could be pulled taut, and attempts were produced to hold the measure level so as to enhance accuracy.



Leaps and bounds in accuracy in surveying have been produced with the introduction of such equipment because the surveyor's compass and theodolite. The surveyor's compass, or circumferentor, consisted of a brass circle and an index; around the circle was a compass. It was used to measure horizontal angles. A theodolite could measure both horizontal and vertical angles. Because of the greater accuracy, the theodolite was the preferred tool for surveyors throughout Europe by the early 1800s. On the other hand, simply because of its bulk, the surveyor's compass was nonetheless used in heavily wooded areas, leading to its resurgence in popularity through the Colonial period in the Usa.



Theodolites, even though more sophisticated versions, were still used as late as the 1990's for uncomplicated surveys, along with other equipment to enhance the accuracy. Far more not too long ago, modern electronics have enhanced on the theodolite with all the addition of an electronic distance measurement device, or EDM; these tools are known as total stations. In a quick time frame, total stations have gone from being mechanical/electronic devices to purely electronic systems with onboard laptop or computer and software.



International Positioning Systems have also entered the arena of land survey, and have steadily gained in knowledge and use inside the private sector. For land surveying, on the other hand, they're not always as correct because the surveyor would wish. Even though they've enhanced the speed of surveying, GPS systems are only horizontally correct to 20mm and vertically accurate to about 30mm. Also, GPS systems have problems functioning appropriately in heavily wooded locations. In lots of cases, surveyors will nevertheless depend on their total stations in conjunction with other equipment like laser scanners. Exactly where the budget is huge enough, a helicopter equipped having a GPS system can verify the findings around the ground.



Even though the technology used by land surveyors has been changing and moving forward by leaps and bound in the last 25 years, even by far the most advanced technology can only do so much. Land surveying remains an art, together with the expertise of the surveyor can't be replaced by technologies. The surveyor should investigate and infer what the true boundaries of any property may perhaps be using both the technological and historical information they've at hand.
