Land surveyors perform a variety of measurements dealing with ground, air and water surfaces. The purpose is to accurately collect data in order to establish boundaries necessary for planning, designing or construction management. These measurements often help to establish land ownership or are needed for legal documentation. A land surveyor will also research previously recorded data and compare that information with their own measurements.
Surveyors rely on mathematics, physics, engineering and the law to guide them in their craft. Equipment that might be used by a surveyor includes: total stations, robotic total stations, GPS receivers, prisms, 3D scanners, radios, handheld tablets, digital levels, and surveying software.
