Detailed data on your infrastructure

The Arctia survey creates a fully integrated model of underwater and above water infrastructures. The integrated 3D model is precise in details.

Arctia offers a wide range of hydrographic and coastal infrastructure engineering services. Survey results are 3D point clouds, which Meritaito experts build into an extremely accurate, fully integrated model of underwater and above the water infrastructures. Experts analyze the data and point out any changes in the structures. Typical issues found include quay wall damages, scouring that has led to slope deformation as well as foreign objects and other changes on sea bed.

3D point clouds and Infra-models

High resolution multibeam echo sounder gives excellent point cloud data from sea bottom to find out objects with different size and shape. Arctia uses multibeam echosounders and laser scanner together to get full point cloud data from waterfront structures. Underwater data fulfills information useful for city planning in waterfront areas. When extreme preciseness is needed, the survey results can be further enhanced with a scanning sonar survey, which is the most accurate underwater survey method available.

Based on the 3D model analyses Arctia experts can point out the critical underwater areas needing immediate closer examination. Furthermore, Arctia can build a infra-model and long-term maintenance plan that helps customers to maintain their infrastructure in systematic and effective way.
