Compare topographical features or contour lines with images from aerial photographs, old maps, or other reference materials to verify the accuracy of their identification.

17-1022.00 Surveyors
  • 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.
