Using 3D photogrammetry to create highly accurate visual computer models
Our models visually expose structures or environments that are not possible to see using traditional methods, producing permanent records that can be continuously assessed and used for whatever the client needs. We make the water disappear virtually, producing clear visibility even in turbid or low-light conditions.
The models generate accurate and dependable data giving confidence for important management decisions and regulatory reporting. Precision and accuracy achieved using:
- High-end through-water GPS systems for georeferencing;
- Lasers or delineated markers for scaling and orientation;
- Salinity-corrected pressure sensors for depth measurement.
Accurate and reliable observations of underwater structures and environments are vital for the aquaculture industry
Beyond the initial survey requirements, our clients have found additional advantages of the models, including exact positioning as to where environmental samples, such as seabed cores, are taken or where invasive species have been identified during biosecurity surveys.
Precise changes can be identified using comparison software on subsequent models which means that fewer surveys are needed to show what is happening over time.
Enhanced Intertidal Surveying: Precision Mapping for Aquaculture
Intertidal surveys employ advanced 3D photogrammetry services using low-tide aerial drone surveys. These capture detailed imagery, creating precise photogrammetric maps for intertidal aquaculture zones. The resulting orthomosaic models integrate geographical data with shore elevation details, offering a comprehensive view.
This detailed insight aids in managing intertidal aquaculture sites with greater accuracy and informed decision-making within the aquaculture sector.
