Marine Mapping

H2H Geoscience Engineering is a leader in providing high-resolution 3D bathymetric survey, mapping, and engineering services for marine environments and large-scale infrastructure projects including locks, dams, spillways, waste weirs, feeder canals, guard gates, lift bridges, embankments, dam safety programs, and ancillary facilities.

H2H’s dual marine mapping solutions, whether deployed alone or paired with our unmanned aerial systems (UAS) drone to perform large-area mapping for projects such as soil erosion monitoring or system-wide local region investigation, are setting a new standard in mapping.

Our marine mapping technologies provide complete terrestrial and bathymetric images and datasets, which increase project safety and reduce costs by delivering all necessary project data in highly-precise 3D data models generated in near real-time that can be used for point cloud analysis, digital surface generation, model creation, volumetric calculation, structural analysis, condition assessment, asset inventory, GIS integration, and CADD drafting.


Our dedicated survey vessel, Atlas, offers precise dual mapping using state-of-the-art, combined Multibeam echosounder (MBES) Sonar and geo-spatially referenced LiDAR and Multibeam data scanners for simultaneous bathymetric and terrestrial scanning up to 200 feet.  

Data collected by Atlas is thoroughly checked for quality and accuracy in real time and displayed and reviewed as it streamed in during survey operations. After minimal post-processing, data sets are used to mine the resulting point clouds to produce detailed images and maps, or extract specific features as specified for clients.

Atlas has been used for Multibeam bathymetric scanning and hydrographic and typographic survey for the New York State Canal Corporation, underwater investigation and 3D imagery for the Federal Emergency Management Agency (FEMA), and harbor maintenance dredging and Multibeam echo sounder survey for the United States Army Corps of Engineers.



For projects such as reservoir investigations and shallow water mapping efforts, H2H deploys the Z-boat, a battery-operated hydrographic survey drone which offers laser-straight survey lines and precise positioning for performing large area or repeating surveys. 

Using advanced radio telemetry and GNSS position and heading technology, the Z-Boat gathers and transmits multibeam data to H2H operators in real-time, allowing for post-processing and creation of point clouds. 

H2H has deployed the Z-Boat for projects including hydrographic survey of lake bottom conditions for Cooper Lake, a reservoir for the Town of Kingston, NY, providing the highest-resolution mapping ever recorded for the reservoir.

“We were using a different laser scanning contractor when we became aware of the mobile laser scanning-based methodology that H2H offers, We made the decision to give it a try and have been very impressed with the results."
