GroundHawk

Surveying takes place immediately before the cable trench is backfilled. This allows the routes of cables, elevations and relative laying depths to be documented in detail.

The mapping accuracy is 10cm along the X, Y and Z coordinate axes. This enables reliable digital as-built documentation of the infrastructure actually installed.

You can also document closed trenches by taking photographs before and after construction.

On-site data collection reduces the workload involved in subsequent surveying and manual documentation processes. The digital provision of data facilitates coordination between the construction site, project management and network operators. At the same time, automated progress reports simplify project monitoring and speed up the preparation of as-built documentation.

When laying power cables and fibre-optic cables, GroundHawk enables the precise mapping of cable routes and laying depths. Cables laid in parallel, as well as associated protective conduits, cable ducts and other protective measures, can also be documented. Surveying in an open trench records the actual installation status before the cables are covered with soil again.

In addition to the actual cables, relevant network elements and landmarks can be captured. These include, amongst others, switch boxes and distribution boxes, manholes, masts, transformers, connection points and underpasses. Supplementary georeferenced photographs document the condition of the infrastructure and facilitate the subsequent allocation of measurement data.

It is also possible to map routes that have already been completed, as well as to carry out selective surveys of individual locations.

GNSS positioning, combined with RTK correction data, enables the precise geographical localisation of the objects being surveyed. As the vehicle moves along the cable trench, cameras capture the surroundings from different angles. Using this image data, GroundHawk employs stereo vision to generate a three-dimensional point cloud of the trench and the infrastructure within it.

The surveying data, 3D information and georeferenced photographs are digitally merged and synchronised online. The GroundHawk portal allows users to track the captured pipe routes and project progress. The data can be exported in supported formats, taking into account the relevant coordinate systems and network operator code lists. This ensures that the results are available for further processing in existing documentation and network information systems.
