Land surveying is the process of measuring and mapping the physical features of a piece of land. This includes determining boundaries, marking property lines, and identifying natural and man-made features such as hills, streams, and buildings. Land surveying is essential for a variety of reasons, including property ownership, construction and development projects, and legal disputes.

There are several methods used in land surveying, including Global Positioning System (GPS) surveying, terrestrial surveying, and aerial surveying. GPS surveying uses satellites to accurately determine the location of points on the earth's surface, while terrestrial surveying involves taking measurements on the ground using a variety of tools and equipment. Aerial surveying uses aircraft or drones to capture images and data from above.

The cost and duration of land surveying can vary widely depending on factors such as the size and complexity of the property, the type of surveying method used, and the location. Generally, land surveying can range from a few hundred to several thousand dollars and can take anywhere from a few days to several weeks to complete. It is important to obtain multiple quotes from qualified surveyors before selecting a provider to ensure that you receive a fair price and accurate results.
