Bathymetry

Bathymetric Surveys

Services

Fluvial, maritime and inland waterway mapping - Bathymetry

It corresponds to the three-dimensional measurement of the underwater environment of rivers, lakes, reservoirs, dams and oceans, in order to study the submerged relief. It allows the continuous scanning of large areas to assess the safety of navigation channels and sediment volume, originating a DTM of submerged areas

Solutions

Advantages

Identification of the underwater platform

identificacão-plateforma-subaquatica

Quick and reliable surveys of underwater space

Surveys using different types of reliable vessels adapted to the environment, with mono and multi-frequency probes

Solutions for surveys in deep and shallow water, coastal coastline, open sea and inland waterways

Acquisition of accurate bathymetric information resulting from the use of the dual frequency, high accuracy GNSS receiver

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.

We combine technology with specialised technicians that guarantee excellent results

Our experience in the underwater approach associated with the use of the latest state-of-the-art technology, corresponds to the certainty of obtaining results of superior quality, which provides our clients with the exact information for their projects and makes VIAMAPA a reference in the acquisition of data of this nature
