Land surveying dates back to ancient eras. In fact, the Egyptians likely utilized surveying as they planned and constructed the great pyramids. People have long understood the importance of accurate land surveying because it sets boundaries, which determine who owns which plots of land. In years past, the process was often inaccurate due to rudimentary equipment. Sometimes the surveyor used tools that were of poor quality or in disrepair.
Ancient tools often included the use of sticks, rope, chains, and even body parts such as fingers, feet, and hands. Issues with accuracy were common for surveyors using these tools. As time progressed, equipment advanced to the use of tape measures, slide rulers, logarithmic tables, and calculators.
Land surveying has developed exponentially due to inventions such as the computer and the microchip. With these new technological advances, the process has become both faster and more accurate. Surveyors of today have a wealth of equipment at their disposal. Some of the latest equipment includes:
– Satellite positioning systems that are capable of measuring points or features virtually anywhere on earth from space. An increase in data points utilized has led to clearer images.
– Geographic information system software, which can capture data and analyze it to create highly detailed digital maps.
– Terrestrial mobile LIDAR scanning has the capability of gathering data taken at high speeds to streamline the process.
– Robotic total stations can calculate slope distances down to the nearest centimeter at the touch of a button.
– 3D laser scanners have the ability to interpret shapes of land to aid in visualization and analysis.
Modern land surveying demands monitoring current technology on a continual basis to stay abreast of new developments and equipment. As newer technology allows professionals to plan projects more precisely, they can ensure the best possible land use, which benefits both clients and the environment.
