Unmanned operation
Reduced exposure in water bodies and restricted-access areas.
USV bathymetry
Safe, precise measurement of
submerged terrain.
Georeferenced depths and bottom models for hydraulic studies, capacity and sedimentation.
USV bathymetry
An integrated navigation, depth and positioning system.
Green Site Engineering performs bathymetric surveys with unmanned surface vehicles (USVs), integrating an echosounder and GNSS positioning. Planned navigation captures georeferenced depths while reducing personnel exposure in difficult-access areas. Data is processed into profiles, bathymetric contours and bottom models for engineering use.

Methodology
A controlled path from scope to delivery.
01
Reconnaissance
Assess access, expected depth, obstacles and vertical reference.
02
Line plan
Define navigation lines, spacing and coverage controls.
03
Navigation
The USV records position and depth along planned lines.
04
Model
Clean data and generate profiles, contours, surfaces and report.
Frequently asked questions
Technical clarity before mobilization.
What does USV mean?
An unmanned surface vehicle navigates on water while carrying positioning and depth sensors.
Can you calculate sedimentation?
Yes, when a compatible reference surface or previous survey exists for comparison.
Can results use the project coordinate system?
Yes. We define the horizontal and vertical reference to integrate results with surveying, CAD or GIS.
Can you survey any body of water?
Feasibility depends on access, waves, current, depth, obstacles and permits. We assess these conditions before mobilization.
