Infrastructure Corridor Mapping

Client: Power Water Corporation

Orthmosaic mapping of North and South corridor

Rise were one of the first businesses to innovate orthomosaic mapping capability here in the Northern Territory.

Rise was providing drone footage of the Strauss Treatment Plant construction and saw the opportunity for PWC to use aerial mapping to accurately model both the North and South pipelines from Strauss.

Rise used aerial drones to map both corridors by autonomously capturing high-resolution, georeferenced data along the corridors.

This data was then processed to create precise 3D models, digital elevation models and orthomosaic maps which are used for inspection, maintenance and planning.

Corridor mapping is used to measure vegetation clearance; calculated cut-and-fill volumes; monitoring construction.

Aerial mapping eliminates the need for personnel to walk along dangerous, remote or high-traffic infrastructure corridors, while providing highly accurate, actional data that can be used for ongoing monitoring, and is far quicker than traditional land-based surveying.

Thessally Resources are undertaking exploration drilling and bulk testing within the existing Huandot Pit, located approximately 85km south of Darwin.

The existing Huandot Pit contains surface water and groundwater inflows and had been sedentary.

Rise was engaged to undertake a bathymetric survey of the test pit surface water to provide Thessally with comprehensive water volume and sedimentation modelling.

Rise used dual frequency analysis to measure both the sediment and rock bed depths to provide a comparative analysis of sediment depth variations.

The analysis used dual frequency bathmetric survey data, XYZ coordinate date and water surface level measurement using a USV (unmanned surface vehicle).

Deliverables:

-Water volume report

-Sediment report

-Interactive visual model.
