Median Pay: US$58,020
Entry Level: Bachelor's degree
Surveyors make precise measurements to determine property boundaries. They provide data relevant to the shape and contour of the Earth's surface for engineering, mapmaking, and construction projects.

Surveyors typically do the following:

  • Measure distances and angles between points on, above, and below the Earth's surface
  • Travel to locations and use known reference points to determine the exact location of important features
  • Research land records, survey records, and land titles
  • Look for evidence of previous boundaries to determine where boundary lines are located
  • Record the results of surveying and verify the accuracy of data
  • Prepare plots, maps, and reports
  • Present findings to clients and government agencies
  • Establish official land and water boundaries for deeds, leases, and other legal documents and testify in court regarding survey work

Surveyors provide documentation of legal property lines and help determine the exact locations of real estate and construction projects. For example, when a house or commercial building is bought or sold, it may need to be surveyed to prevent boundary disputes. During construction, surveyors determine the precise location of roads or buildings and proper depths for building foundations. The survey also shows changes to the property line and indicates potential restrictions on the property, such as what can be built on it and how large the structure can be.

When taking measurements in the field, surveyors make use of the Global Positioning System (GPS), a system of satellites that locates reference points with a high degree of precision. Surveyors use handheld GPS units and robotic total stations to collect relevant information about the terrain they are surveying. (Robotic total stations use laser systems and GPS to automatically calculate distances between boundaries and geological features of the survey area.) Data is then loaded into a computer, where surveyors interpret and verify the results.

Surveyors also use Geographic Information Systems (GIS) - technology that allows surveyors to present spatial information visually as maps, reports, and charts. For example, a surveyor can overlay aerial or satellite images with GIS data, such as tree density in a given region, and create digital maps. They then use the results to advise governments and businesses on where to plan homes, roads, and landfills.

Although advances in surveying technology now allow many jobs to be performed by just one surveyor, they also may work with the help of a crew. The crew may consist of a licensed surveyor and trained survey technicians. The person in charge of the crew, known as the party chief, may be either a surveyor or a senior surveying technician. The party chief leads day-to-day work activities.

Surveyors may be involved in settling boundary disputes. When property is sold or new construction takes place, such as the building of a fence, issues may arise because of outdated records or the misinterpretation of available records. A surveyor can be called in to settle the dispute, and may provide testimony in court if the involved parties do not come to an agreement.

Surveyors also work with civil engineers, landscape architects, and urban and regional planners to develop comprehensive design documents.

Some surveyors work in specialty fields to survey particular characteristics of the Earth.

The following are two types of surveyors:

Geodetic surveyors use high-accuracy technology, including aerial and satellite observations, to measure large areas of the Earth's surface.

Marine or hydrographic surveyors survey harbors, rivers, and other bodies of water to determine shorelines, the topography of the floor, water depth, and other features.
