Tropical Cyclone Debbie disaster recovery: spatial services
In 2017, RPS' Queensland surveying and mapping teams were on call to help Aurizon bring a vital freight transport corridor impacted by Tropical Cyclone Debbie back into service.
Environmental challenges
Following the devastating impact of Tropical Cyclone Debbie on homes, businesses and infrastructure in North Queensland, RPS deployed to assist Aurizon in assessing damage.
The main focus was the Goonyella Rail Corridor where rail access from coal mines in the Bowen Basin to coastal ports had been blocked.

Spatial solutions
RPS completed LiDAR cross-sections of the tracks, detailing areas of the corridor affected by flooding, subsidence, and debris.
Just 24 hours later our UAV pilots were on the ground to capture detailed aerial photography that would allow us to create 3D models and topographic meshes for use by engineers in rectification works planning.
The rapid deployment of our team just hours after initial contact from Aurizon helped the company resume freight traffic on the rail corridor just four weeks post-Tropical Cyclone Debbie.
