The main surveying instruments in use around the world are the theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. Most instruments screw onto a tripod when in use. Tape measures are often used for measurement of smaller distances.
.
Subsequently, one may also ask, what are two of the tools used by surveyors to measure?
The transit and theodolite are used by the surveyor to measure both horizontal and vertical angles. While the purpose of the two is similar, as a general rule a theodolite is more accurate than a transit.
Subsequently, question is, what exactly does a surveyor do? A surveyor determines property boundaries by taking precise measurements. They provide data for engineering industries, construction projects, and map making that is relevant to their client or employer. A surveyor may prevent legal disputes by updating boundary lines and preparing sites for construction.
Also asked, how does survey equipment work?
The ubiquitous tool for a survey is called a theodolite, and it's one job is to measure the horizontal and vertical angles between points. Combine those angles with distances from a chain or tape measure, and you can triangulate the location of any point using trigonometry.
