Hope Downs 1 - Hope Downs 4 Pipeline

The HD pipeline project is located between Hope Downs 1 & Hope Downs 4 mine site primarily along RTIO rail line, Western Australia.

The project area to provide LiDAR aerial mapping surveys is a combination of brown & green fields with unsealed access tracks and light vegetation. The aerial mapping survey area extents was 60km long corridor, approximately 6,000 Ha.

Certero Surveys was engaged by Rio Tinto – Sustaining Capital to fly the areas of interest to capture topographic data to support the pre-feasibility study phase and design of the HD Pipeline.

The primary data capture was completed with a DJI M350 RTK & DJI Zenmuse L2 LiDAR sensor, capturing RGB imagery & point cloud of the site. The aerial point cloud and imagery was processed to derive an accurate 3D ground profile (50mm vertical accuracy) and orthomosaic of site using LiDAR and photogrammetric procedures.
