Measure large areas of the Earth's surface using satellite observations, global navigation satellite systems (GNSS), light detection and ranging (LIDAR), or related sources.
<ul><li>Calculate the exact horizontal and vertical position of points on the Earth's surface.</li><li>Verify the mathematical correctness of newly collected survey data.</li><li>Maintain databases of geodetic and related information, including coordinate, descriptive, or quality assurance data.</li><li>Conduct surveys to determine exact positions, measurement of points, elevations, lines, areas, volumes, contours, or other features of land surfaces.</li><li>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.</li><li>Analyze control or survey data to ensure adherence to project specifications or land survey standards.</li><li>Plan or direct the work of geodetic surveying staff, providing technical consultation as needed.</li><li>Assess the quality of control data to determine the need for additional survey data for engineering, construction, or other projects.</li><li>Request additional survey data when field collection errors occur or engineering surveying specifications are not maintained.</li><li>Distribute compiled geodetic data to government agencies or the general public.</li><li>Review existing standards, controls, or equipment used, recommending changes or upgrades as needed.</li><li>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.</li><li>Provide training and interpretation in the use of methods or procedures for observing and checking controls for geodetic and plane coordinates.</li><li>Prepare progress or technical reports.</li><li>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.</li><li>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.</li></ul>
