Measures large areas of the Earth's surface using satellite observations, global navigation satellite systems (GNSS), light detection and ranging (LIDAR), or related sources.
This career is part of the Architecture and Construction cluster Design and Pre-Construction pathway.
A person in this career:
- Calculates the exact horizontal and vertical position of points on the earth's surface.
- Maintains databases of geodetic and related information including coordinate, descriptive, or quality assurance data.
- Verifies the mathematical correctness of newly collected survey data.
- Conducts surveys to determine exact positions, measurement of points, elevations, lines, areas, volumes, contours, or other features of land surfaces.
- Computes 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.
- Analyzes control or survey data to ensure adherence to project specifications or land survey standards.
- Assesses the quality of control data to determine the need for additional survey data for engineering, construction, or other projects.
- Plans or directs the work of geodetic surveying staff, providing technical consultation as needed.
- Requests additional survey data when field collection errors occur or engineering surveying specifications are not maintained.
- Distributes compiled geodetic data to government agencies or the general public.
