Land surveys and land mapping are an integral part of every town and city. You may not be aware of it but surveying is essential to most construction, engineering, and mapping projects and it has been around for centuries.
In fact, surveying has been around for approximately 6,000 years. Evidence of land surveying has been found in the following monuments and civilizations:
- Stonehenge (peg and rope geometry).
- Ancient Egypt (surveyors were utilised prior to the construction of the Great Pyramids, as well as to reassess boundary markers following overflows of the Nile River).
- Mesopotamia (first use of the early surveying tool – Groma).
- Ancient Greece (developed the diopter, another early tool used for surveying purposes. Their knowledge of geometry also came into play, and they began to standardise procedures for surveying).
- Ancient Rome (recognised land surveying as a true profession).
A significant event also occurred in the year 1086, when England’s William the Conqueror ordered the Domesday Book, a record of landowners and the plots they occupied. This furthered the importance of exact boundaries on personal property.
Surveying Services Boom
As science and technology progressed, so too did the surveying industry. Triangulation was created in the 1600’s and is still vital to modern surveying. In 1787, Jesse Ramsden created a tool that measured angles in horizontal and vertical planes.
At the start of the 19th century, the Industrial Revolution was taking hold and more accurate and effective surveying instruments were being created. This period saw a boom in the surveying industry as surveyors were required to assist in the construction of roads, railways, canals, and other infrastructure.
Land Surveying Technology
Land surveying technology has continued to improve and evolve and land surveyors can now record and report data far more quickly and with greater accuracy. Some of the surveying equipment commonly used today include:
- 3D laser scanners
- Satellite positioning systems
- GIS software (high-tech software used for the creation of Google Maps)
- Deep tows (deep ocean floor survey systems)
