Three commonly used survey measuring tools are:
- Total Station: A total station is a high-precision electronic surveying instrument that combines the functionalities of a theodolite (for measuring angles) and an electronic distance measuring device (for measuring distances). It is equipped with a telescope, electronic angle measurement system, and a distance measurement system (such as EDM or electronic distance meter). Total stations enable surveyors to measure both horizontal and vertical angles, as well as distances, with high accuracy. They are often used for various surveying applications, including boundary marking, topographic mapping, and construction layout.
- Global Positioning System (GPS): GPS is a satellite-based navigation system that allows for accurate positioning and data collection in land surveying. GPS receivers receive signals from multiple satellites to determine the surveyor’s precise location on the Earth’s surface. GPS surveying provides highly accurate measurements of coordinates (latitude, longitude, and elevation) and can be used for tasks such as establishing control points, mapping, and geodetic surveys. It offers the advantage of quick data collection over large areas, making it efficient for large-scale survey projects.
- Measuring Tape: A measuring tape, also known as a tape measure, is a simple but essential tool in land surveying. It consists of a flexible ribbon or tape with markings that indicate length or distance. Measuring tapes come in various lengths and are made of materials like steel or fiberglass. They are used to measure distances on the ground, such as the dimensions of a plot, the length of a boundary line, or the width of a road. Measuring tapes are versatile and easy to use, making them a common tool in field surveying operations.
These survey measuring tools are integral to the field of land surveying and enable surveyors to obtain accurate measurements of distances, angles, and coordinates. They are selected based on the specific requirements of the surveying project and the level of precision needed for the measurements.
