Surveyors provide data regarding the location, shape, contour, elevation or dimensions of land or land features. Surveyors set official land, water and airspace boundaries. They provide written descriptions of land for leases, deeds and other types of legal documents. They also take measurements of construction and mineral sites. Some surveyors define airspace for airports.
Surveyors measure directions, distances and angles between points on, below and above the surface of the earth. A surveyor utilizes specialized equipment to determine the precise location of important features in the survey area. They use the Global Positioning System to locate reference points with a high degree of precision.
Geophysical prospecting surveyors mark sites for subsurface exploration, typically to search for petroleum. Geodetic surveyors measure large areas of the earth's surface using high-accuracy techniques, including satellite observations. Marine or hydraulic surveyors survey rivers, harbors and other bodies of water in order to determine shorelines, water depth, the topography of the bottom and other features.
Some sample job titles are land surveyor, county surveyor, geodesist, mine surveyor, professional land surveyor and licensed land surveyor.

Surveyors usually work 40 hours a week and spend a lot of time outdoors. They sometimes walk far distances and climb hills with heavy backpacks containing instruments and other equipment. They also stand for long periods of time. Travel is sometimes part of the occupation. They also may temporarily live near a surveyor site. In addition, a surveyor needs to work with precision and accuracy. They also need good analytical skills.
The employment growth for surveyors has been forecasted by the Bureau of Labor Statistics to be 15 percent from 2008 to 2018. The median annual wages for surveyors in 2008 was $52,980. The highest paid 10 percent earned more than $85,620.
Education, Certification, and Licensing
Most surveyors need a bachelor's degree in surveying or a related field. Many vocational schools and community colleges provide one-year, two-year and three-year programs in surveying or surveying technology.
Every state licenses surveyors. For licensure, most state licensing boards require applicants to pass a series of written examinations provided by the National Council of Examiners for Engineering and Surveying. Most states also require surveyors to pass a written examination developed by the state licensing board.
The requirements for education and training vary among the states. An increasing number of states require surveyors to have a bachelor's degree in surveying or in a closely related subject such as civil engineering or forestry, regardless of the number of years of experience. Some states require surveyors to have a degree from a school that has received accreditation from the Accreditation Board for Engineering and Technology.
