How do they match: Surveying and Mapping Technicians

  • Surveying and Mapping Technicians

  • Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
  • Record survey measurements or descriptive data, using notes, drawings, sketches, or inked tracings.
  • Adjust and operate surveying instruments such as prisms, theodolites, electronic distance measuring equipment, or electronic data collectors.
  • Collect information needed to carry out new surveys, using source maps, previous survey data, photographs, computer records, or other relevant information.
  • Conduct surveys to ascertain the locations of natural features and man-made structures on the Earth's surface, underground, and underwater, using electronic distance-measuring equipment, such as GPS, and other surveying instruments.
  • Perform calculations to determine earth curvature corrections, atmospheric impacts on measurements, traverse closures or adjustments, azimuths, level runs, or placement of markers.
  • Position and hold the vertical rods, or targets, that theodolite operators use for sighting to measure angles, distances, and elevations.

  • Survey land or bodies of water to measure or determine features.
