The closer, the more precise.
The key to the 3 D structure survey is the level of detail of the measurement, which we coordinate with you. The measuring points are visualized in a point cloud and can be determined using various methods: by laser scan, multibeam and photogrammetry from land, water or air. The perspective makes the difference.

Vertical orthophotos (VDOP) provide a special added value, for example for the preparation of the inspection of structures, with high-contrast, high-resolution and zoomable HDR images. In the geo-referenced version, lengths and areas of all project participants can even be determined in these images via our data portal HydroCloud. These photographs can be processed into a point cloud and linked with any existing underwater data.
A bird's eye view is best for an overview. Even with orthogonal images (DOP) from the air, it is crucial how detailed the target should be recognized on the ground in order to meet your requirements. For example, for construction site equipment, terrain models or to prepare a BIM-compliant building model.
As if you were there. Everyone involved in the project can take a leisurely look around the scene, move around and zoom in to the tip of their nose. At jointly determined vantage points, you can experience the site or buildings 'up close' and you will not miss a single detail.
With the underwater survey at BIM level, you receive a comprehensive and structured image from the bottom to the waterline, which makes it possible, for example, to identify suspected damage points, to efficiently control our certified building test divers or to start monitoring the structure's life cycle.
We can see what you are not seeing: A look behind the scenes is priceless. If there is more than one row of piles to be recorded, HydroMapper can look at measurements up to the 6th row of piles, which also became the basis for BIM planning.
Particularly large depths do not prevent HydroMapper from achieving a high level of detail. Whether at a depth of over 25 m in a small, impassable excavation or in a whole lock chamber, we will coordinate the necessary accuracy of the data with you and show you the appropriate surveying solution.
