What do Geodetic Surveyors do?
Measure large areas of the Earth's surface using satellite observations, global navigation satellite systems (GNSS), light detection and ranging (LIDAR), or related sources.
- Analyze control or survey data to ensure adherence to project specifications or land survey standards.
- Calculate the exact horizontal and vertical position of points on the earth's surface.
- Verify the mathematical correctness of newly collected survey data.
- Plan or direct the work of geodetic surveying staff, providing technical consultation as needed.
- Assess the quality of control data to determine the need for additional survey data for engineering, construction, or other projects.
- Maintain databases of geodetic and related information including coordinate, descriptive, or quality assurance data.
- Conduct surveys to determine exact positions, measurement of points, elevations, lines, areas, volumes, contours, or other features of land surfaces.
- Compute horizontal and vertical coordinates of control networks using direct leveling or other geodetic survey techniques such as triangulation, trilateration, and traversing to establish features of the earth's surface.
- Request additional survey data when field collection errors occur or engineering surveying specifications are not maintained.
- Read current literature, talk with colleagues, continue education, or participate in professional organizations or conferences to keep abreast of developments in technology, equipment, or systems.
- Compute, retrace, or adjust existing surveys of features such as highway alignments, property boundaries, utilities, control and other surveys to match the ground elevation dependent grids, geodetic grids, or property boundaries and to ensure accuracy and continuity of data used in engineering, surveying, or construction projects.
- Prepare progress or technical reports.
- Determine orientation of tracts of land including position, boundaries, size, and shape using theodolites, electronic distance measuring equipment, satellite-based positioning equipment, land information systems or other geodetic survey equipment.
- Distribute compiled geodetic data to government agencies or the general public.
- Review existing standards, controls, or equipment used, recommending changes or upgrades as needed.
- Provide training and interpretation in the use of methods or procedures for observing and checking controls for geodetic and plane coordinates.
