Aquatic and Hydrographic Surveying

Hydrography is the science that measures and describes the physical features of bodies of water and the land area adjacent them. With the advent of high-accuracy GPS in conjunction with echo sounders, surveyors are now able to map the “floor” of tidelands and bedlands. San Juan Surveying utilizes the Seafloor HydroLite™ single beam sonar in conjunction with our Topcon Hiper V GPS dual frequency GNSS receiver all attached to our 23’ North River Seahawk. With this combination we are able to provide verifiable marine topographic data to Ports, Marinas and Private dock owners in the San Juan Islands and the greater Puget Sound. We provide support and mapping for:

  • Bathymetric Mapping
  • Aquatic Surveys
  • Marina Surveys
  • Marine Construction Support
