Infrastructure

Infrastructure, effective monitoring

Topographic data are essential to drawing, build or maintain the roads, railways, sewage networks, waterways, dams, power lines, pipelines, etc.

ATGT offers aerial & marine surveying, using the latest technology sensors: digital, acoustic & thermal cameras, Lidar, MMS (Mobile Mapping System) and sonars. We also process satellite imagery.

We offer solutions for infrastructure management.

Detection of anomalies and stability measurements

ATGT measures the distances to obstacles and vegetation around electrified constructions. We can detect power line anomalies, fine cracks in dams or pipeline corrosion.

ATGT makes stability measurements all through the construction phase. Emergency systems are set up to alert the project team in real time.

DIGITAL TERRAIN MODEL (DTM) & DIGITAL SURFACE MODEL (DSM)

The DTM shows the bare ground, no vegetation, no earthwork. We can then study and prevent any water flows or flooding situations.

DTM & DSM shows a 3D picture of every object on the ground: buildings, vegetation and earthworks.

Orthophoto maps

From the DTM, we can make orthophoto maps, which describe very precisely the environment and the surface area. It is a set of corrected images processed by the DTM. Orthophoto maps provide the same quality for geometry details as those of a map.

Geographic database

The topographic map is a geographic object database (kerbs, buildings, roofing style, rails, electric cables, etc.) using 3D geometry.

3D Modeling

3D models virtually show the structure of a building, a housing complex, an entire town or any infrastructure in its environment. The model matches reality perfectly and allows you to visualize any development project in its real environment.

Bathymetry

Bathymetry allows the measurement of silting volume in reservoir waters.

ROADS & NETWORKS

ATGT offers a global solution for the design and the construction of roads & networks (VRD): we meet with the private & public operators, we help you with the administrative procedures, we prepare the dossiers, we make the plans, we choose the materials, we supervise the activities on-site, etc.
