High resolution multibeam echosounder combined with 3D scanner laser system are new topographic and bathymetric generation of sensors. They allow to collect several millions of geo loacalized data points in few minutes with centimeter accuracy.
These sensors are used increasingly as complete and quick solution for the study of the state or behaviors of structure
In complex areas where regular vessel launching is impossible, GEOSUB 3DTM subsurface system is the solution to collect high resolution datas in a very short time.It can be deployed on crane hook or any lifting devices. GEOSUB 3D provides high resolution of natural rocks or artificial units without visibility. In addition to real time display, the high resolution DTM produced is ideal for volume computations or underwater placement qualification.
