Hydrographic/Bathymetric Survey Services

UMS approaches hydrographic surveying as a highly specialized and strategic professional engineering service. 

Each project inherently has unique problems and characteristics that can be best handled through a suitable application of professional experience, technology, and local knowledge. UMS staff has over 120 cumulative years of hydrographic survey experience, including recent (May 2017) training with state-of-the-art NORBIT multibeam sonar, with additional expertise in global navigation satellite systems (GNSS) and geographic information system (GIS) data management.

The UMS team provides the following:

  • Engineers and surveyors with hydrographic experience using the NORBIT iWBMSc Kit including:
    • NORBIT WBMS multibeam sonar (agile frequency with 80kHz bandwidth for FM operation)
    • AML integrated surface sound speed sensor
    • Applanix OEM-AP20 (same as Applanix Wavemaster)
    • Topside interface unit (IP67)
    • Hypack/Hysweep
  • Engineers trained in the theory, use, limitations, and pitfalls of both single and multibeam sonars.
  • Survey crews specialized in robotic total station and RTK GPS methods to achieve required spatial accuracies within the allowable tolerances.
  • Data management using secure, web based Geographic Information System (GIS) applications including ESRI ARCGIS and WebGIS.
  • Computer aided 3D drafting and design using latest Autodesk and Bentley applications.
  • Professional report prepared by the assigned registered engineer of record.
  • Knowledge of civil engineering design procedures.
  • Reputable personnel to provide:
    • expeditious data acquisition and processing
    • responsive, close coordination with public agencies and client officials and engineers
    • long-term accountability and availability
    • Project management expertise on large multi-tasked contracts.
