Identify, scale, and orient geodetic points, elevations, and other planimetric or topographic features, applying standard mathematical formulas.
- Calculate heights, depths, relative positions, property lines, and other characteristics of terrain.
- Determine longitudes and latitudes of important features and boundaries in survey areas, using theodolites, transits, levels, and satellite-based global positioning systems (GPS).
- Compute geodetic measurements and interpret survey data to determine positions, shapes, and elevations of geomorphic and topographic features.
- Calculate the exact horizontal and vertical position of points on the Earth's surface.
- 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.
- 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.
- Calculate latitudes, longitudes, angles, areas, or other information for mapmaking, using survey field notes or reference tables.
- Compare topographical features or contour lines with images from aerial photographs, old maps, or other reference materials to verify the accuracy of their identification.
- Compute and measure scaled distances between reference points to establish relative positions of adjoining prints and enable the creation of photographic mosaics.
- Perform calculations to determine earth curvature corrections, atmospheric impacts on measurements, traverse closures and adjustments, azimuths, level runs, and placement of markers.
