GEOSUB 3D

MESURIS is the first company to have designed and produced a very high resolution underwater mapping system, usable without any conventional survey vessel. GEOSUB 3D^TM is a mobile multibeam bathymetric unit designed to produce a high resolution DTM from a site crane very quickly for all types of shallow water marine projects.

More simple and less expensive than a multibeam survey vessel

Minute survey : calibrated inspection system, immediately operational to display in real time high resolution bathymetry. It only needs a single operator.
Can be used directly from the hook of the crane on the building site and does not require a survey vessel.
Reduced project time due to rapid and frequent follow up.

Extremely accurate

Production of a digital terrain model «as built» of high resolution topographic quality.

- There are less shadow areas, because radial beams. Inertial motion sensors and RTK positioning (centimeter accuracy) are combined for exact cartography of complex volumes geometry.
- Coverage over 160°, much more than an acoustic camera.
- Points density up to 1000 /m² to produce digital terrain models with 10 x 10 cm cells

More secure and efficient

Replaces underwater diver inspections
More accurate and faster than any manual method.
Inspection possible even during rough seas.
under ice or ice floe survey

OPOMETRYX-GEOSUB 3D^TM option : multibeam laser topographic system simultaneously maps above the water.

Adaptation to the request

MESURIS technicians are operating GEOSUB 3D^TM on site for selective inspections.
Lease systems and training for short projects with optional data processing.
Delivery of GEOSUB 3D^TM systems for permanent use.
