Our company has significant experience in the planning and execution of underwater surveying and mapping. More recently, we are combining traditional mapping techniques with 3D photogrammetry, and this is a major tool used in delivery.
The areas of mapping we have achieved ranges from a few square metres up to 100s of m2. These areas are influenced by a number of factors including: the main objectives of the project, the depth of water, the clarity of the water, the funding/time available, and tidal conditions.
We have applied our mapping techniques to a wide range of applications, from quantifying the impacts of subtidal outflows to generating area-specific indices of the health and carbonate production capacity of tropical coral reefs. However, this wide range can be catagorised by three main 'themes'; these are the assessment of:
- Environmental condition, impact and recovery
- Condition and layout of underwater and intertidal structures
