Bathymetry by drone

Water drones

The water drone emerged as a response to a need that work taking place on the bathymetric had already identified.

This equipment, developed by the Research and Development Department of VIAMAPA - GEOSAT Group, is remotely controlled and allows underwater prospection.

Technology

Latest generation 

It is particularly crucial and extremely useful in situations where other vessels have more difficulty or cannot obtain the necessary information.

Using the aquatic drone, it is possible to collect data in environments that are difficult to access, such as shallow waters, circumstances where algae and similar occur.
