Tasks

  • Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
  • Design or develop information databases that include geographic or topographic data.
  • Monitor mapping work or the updating of maps to ensure accuracy, the inclusion of new or changed information, or compliance with rules and regulations.
  • Produce or update overlay maps to show information boundaries, water locations, or topographic features on various base maps or at different scales.
  • Determine scales, line sizes, or colors to be used for hard copies of computerized maps, using plotters.
  • Identify and compile database information to create maps in response to requests.
  • Analyze aerial photographs to detect and interpret significant military, industrial, resource, or topographical data.
  • Enter Global Positioning System (GPS) data, legal deeds, field notes, or land survey reports into geographic information system (GIS) workstations so that information can be transformed into graphic land descriptions, such as maps or drawings.
