Surveying includes many special fields. Land surveyors establish and mark property lines. Marine surveyors map shorelines and depths of water bodies. Engineering surveyors survey sites of buildings, roads, sewers, and other projects. Geodetic surveyors set reference points for use by other surveyors.
Surveyors work for private surveying or engineering firms.
Many work for state or local highway departments. Some are self-employed. They usually work eight- hour days, five days per week, although longer hours may be required in summer. Surveyors do much of their work out- doors, but they also work indoors when doing computations, writing reports, and drawing maps. Surveyors perform work concerned with measuring elevations, contours, curvatures, and other physical features of land and water properties and determining their exact locations and boundaries.
