Bridging geography and informatics, geomatics defines the practices and technologies that enable the collection, analysis and sharing of geographic data.

Bathymetric charts

From acquisition to chart production, we master the quality of the workflow.

On request, our bathymetric surveys can be carried out in compliance with the International Hydrographic Organization IHO S-44 standard which sets out “special order” measurement conditions for critical navigational areas, such as rivers, channels and harbours, for which the under-keel clearance is critical for navigation.

In order to represent these data in the form of navigational charts, our hydrographers produce ENC (Electronic Nautical Charts) in accordance with the S65 “Production, Maintenance and Distribution Guidance” specifications from the IHO.

Finally, the charts are delivered to the S57 standard, which is the the only navigational format to be officially recognized by the IHO.

For hydrographic services that want to generate their own cartography, Deparentis is also distributor of the application ULHYSSES and PORTSIDE from GEOMOD. These simple and precise tools allow creating automatic S57 bathymetric charts from your own multi-beam survey. For more information: Go here.

Precision positioning

The position requirements of marine surveying are one of the most demanding.

It is easy to understand that at sea, without fixed landmarks, accurate and reliable positioning is essential. This accuracy is key for safety, navigation and operations as on offshore rigs, pipelines installation or the deployment of Remotely Operated Vehicles (ROVs).

This places stringent demands on the hardware and software that provide this positioning service, but also on the expertise of the staff.

To implement the most modern solutions, Deparentis relies on experienced and qualified personnel, all BOSIET & HUET certified.

Drone survey

A cost-effective, accurate and efficient way to generate mapping data

Hydrographic survey with USV (Unmanned Surface Vehicle) boats or aerial mapping by RPAS (Remotely Piloted Aircraft Systems) techniques have made considerable progress in recent years.

We use remote controlled boats USVs (Unmanned Surface Vehicles) for hydrographic surveys in cluttered waters such as marinas, very shallow waters, or in areas with hazardous operating conditions.

In addition to our core competence in the maritime, we sometimes need to use an airborne drone in specific environments such as inaccessible beaches, breakwaters etc. This technique allows us to carry out remote sensing at LiDAR or topographic surveys in a safe and economical way.

LiDAR mapping

New technologies for high-resolution mapping both under and above the waterline.

By complementing traditional bathymetric data (xyz) with topographic heights, bathymetric LiDAR (Light Detection And Ranging) is the most effective technology to capture both the land and seafloor simultaneously to provide a continuous, detailed 3D elevation model along the coastline.

LiDAR data supports activities such as hydrodynamic modeling, shoreline mapping, hydrographic surveying, and coastal vulnerability analysis.

As appropriate, we operate LiDAR mapping systems mounted on drones (RPAS) or boats (UAV).
