Land surveying plays an integral part in the construction process, and it's necessary to have the right equipment in order to get the job done properly. Here are four pieces of equipment that land surveyors use on a regular basis.
A theodolite is a tool that is used to measure distance and angles in both the horizontal and vertical planes. The horizontal and vertical angle measurement devices use an electro-optical scanning method to measure angles, while the distance measuring device uses an infrared laser to measure distance. In order to obtain accurate measurements, the theodolite must be level and aligned with the intended point of measurement. Theodolites are typically mounted on tripods, and they are used to establish lines of sight for surveying purposes. Today, theodolites are used in a variety of applications, including construction, mining, and land surveying.
2. GPS Receiver
Surveyors commonly use GPS receivers to determine their precise location on the earth's surface. The basic principle behind using GPS for surveying is that the receiver can calculate its position by measuring the distance to several satellites in orbit around the earth. By knowing the precise location of these satellites and the speed at which they are moving, the receiver can calculate its own position with a high degree of accuracy.
3. Ranging poles
Ranging poles are a key tool for any surveyor. They are used to mark lines of sight, helping to ensure that measurements are taken correctly. Ranging poles are typically made of materials such as fibreglass or wood, and they are usually brightly coloured so that surveyors can easily see them. Fibreglass poles are particularly useful as they are lightweight and easy to carry, making them ideal for use in rugged terrain.
4. Laser Level
Laser levels are an essential tool for land surveyors. When creating a level reference line, accuracy is crucial in order to ensure that the line is truly level. Laser levels provide the precision needed to create a line that is level to within a few millimetres. This high degree of accuracy is possible because laser levels use a beam of light to create the reference line. The light from the laser is reflected off things and projected onto the ground, creating a visible line. This method of calculating a level is much more accurate than using a traditional air bubble level, which can be prone to errors.
