In the 1920s, Underhill completed numerous triangulation surveys for topographic mapping and coastal charting throughout BC. We continue to provide these geodetic surveying services today—albeit with much greater accuracy and efficiency:

  • project planning and logistics,
  • geodetic control,
  • precise levelling,
  • automated control observation collection and processing,
  • rigorous least-squares adjustment and analysis of results,
  • geoidal modeling, and
  • datum transformations.
