Surveyors use advanced technology to create accurate representations of land, including mountains, valleys, and oceans. They work for government and private institutions, and can specialize in fields such as astronomy or oil exploration. A college degree is required, with many starting as assistants to gain experience.
A surveyor is a specialist in geology and geography who surveys pieces of land and creates highly accurate representations. It uses sophisticated computer equipment to ensure accurate measurements of the elevation, location, shape and contours of a specific area. Many surveyors work for government and private research institutions to study the Earth’s surface features. Professionals can also be employed by oil companies, land development companies and engineering companies to provide practical and reliable information about drilling and construction sites.
A survey surveyor conducts careful field studies to map mountains, valleys, lakes, glaciers and even the ocean floor. He or she relies on advanced technologies such as global positioning system (GPS) devices, laser sights, radar systems and aerial cameras. Surveyors enter data into computer simulation programs to create accurate three-dimensional representations of landforms. Using their findings, professionals can track changes over time and learn how certain features were formed. Many researchers divide their time between field observations, research and student instruction at universities.
Some researchers with specialized knowledge in astronomy study the surfaces of planets, moons, stars, asteroids, and other distant bodies. They use telescopes and powerful satellite data to identify peaks, valleys, craters, volcanoes and many other important features. When a surveyor cannot get a clear view or image, he or she can still identify certain properties by analyzing shadows and orbital patterns. Like other types of survey surveyors, astrology specialists are generally employed by specialized government institutions, private laboratories, and universities.
A surveyor can also work as a consultant for companies that specialize in oil exploration or construction. Surveyors at oil companies typically work alongside geologists and oceanographers to pinpoint the location of oil deposits with GPS devices, measure their width and decide how deep the company should drill. Land development and civil engineering companies often work with surveyors to determine the best methods for excavating and incorporating natural land contours into design designs.
A college degree is required to become a surveyor in most situations. Most working professionals have at least a bachelor’s degree in geography, geology, or cartography. A doctorate is often required if an individual wants to conduct independent research or teach at a university. University courses in surveying and related subjects allow students to become familiar with the different tools and techniques used in the field. Most new surveyors start their careers as assistants to established professionals to gain hands-on experience and build their credentials.
