  • 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 and drawings.
  • Produce or update overlay maps to show information boundaries, water locations, or topographic features on various base maps or at different scales.
  • Trim, align, and join prints to form photographic mosaics, maintaining scaled distances between reference points.

  • Calculate geographic positions from survey data.
