Services: Hydrographic Surveys

Hudson performs its hydrographic surveys with the option of utilizing the latest sonar and inertial GPS technology available in the industry.  Real Time Kinematic (RTK) is broadcast to the survey vessels, achieving centimeter vertical and horizontal accuracies. If a project is in a remote geographic location with no possible way to establish RTK, software is readily available allowing the data to be post processed to the same tolerances as RTK. Having the ability to conduct a scanning sonar or multibeam survey with diver verification is a key tool to Hudson Engineers in house capabilities. Consulting on a variety of dredging related issues, including preparation of specifications, pre- and post-dredge surveys, monitoring of siltation rates, volume calculations used in payment quantities, and assistance in obtaining required local, state and federal permits for dredging applications. All of these key components allow us to provide our clients with the most accurate, timely, and cost effective deliverables available.
