Multibeam bathymetry


Specialists in shallow water multi-beam survey since 2000

MESURIS Bathymetry has started year 2000 operating professional vessels permanently equiped for shallow water multi-beam bathymetry. Our SURVEX vessel, fully built in aluminium provides high resolution and the best accuracy for your surveys. Operations are marketed in France and Europe . More than 2000 survey days have been produced (end 2016).



SURVEXTM is a multibeam bathymetry mobile vessel. It is built to provide quickly bathymetric data in marine or fresh water areas with a full bottom coverage.

 SVX laser


  • Equiped with multibeam echosounder, inertial navigator, centimetric GPS RTK positionning system, SURVEX is the tool for shallow water high resolution survey.
  • Survey is performed with TELEDYNE RESON seabat 8101 or 7125 HR multibeam echosounder. Unique equipment which allows to survey total bottom coverageup to the water level with 210° swath angle. Considerable number of sounding data point produce digital terrain models "as-buit"
  • 3D scanner laser system TOPOMETRYXTM HR permanently installed onboard is designed to map structures and dikes above water line.
  • Carried by road fully equiped, launched nearest as possible from survey area, SURVEX is ready to work 1 hour after its arrival.
  • Launching is done with the hydraulic crane on our semi articulated lorry DPX carrying SURVEX vessel. All sensors are always installed onboard, sothat there is no need to perform a new calibration on site. Periodic calibration controls are done in deep marine area near our technical base of La Trinité-sur-Mer

From post processed bathymetry data, our team based in Brittany (RENNES-Saint Grégoire) produces in a very short time : 

  • bathymetric charts in Autocad and PDF format
  • high resolution DTMs
  • cross profils, volume computation
  • interactive 3D files BATHYRELIEFTM

    • From one day on site

Bathymetric surveys are proposed according to a daily fixed-price contract including SURVEX fully equiped transported on site and the crew. Post processing is although proposed according to a daily fixed-price contract including the staff and computing.

Fields of intervention

+ Harbour multibeam survey
In only one day, SURVEX vessel surveys in high resolution most of the harbour and provides datas for volume calculation. Breakwaters can be mapped with 0.10 x 0.10m cells and topography above water line done simultaneously by TOPOMETRYXTM HR 3D scanner laser unit.

+ Coastal bathymetry
1 to 3 Km2 are covered each day. Side scan sonar imagery is also availlable (maximum 25m depth) and ultra-high resolution sub-bottom profiler designed for shallow water environments

+ Canals, lakes and rivers
up to 15 km of canal can be covered each day using GPS+GLONASS positioning blended with inertial navigation
