Main Roads WA and their contractor Cardno embarked on the assessment of specific topographical conditions for a new 100km road in the remote Hammersley Ranges, located over a thousand kilometers from Perth and required a video flyover.
The primary goal was to gain a comprehensive understanding of the terrain and estimate the amount of material that would need to be moved for the new road corridor.
This operational area presented several formidable challenges. The remote and hazardous terrain, coupled with high ambient temperatures, made traditional surveying methods impractical and posed significant safety concerns for surveying teams and equipment.
RemSense proposed a multifaceted solution to address these challenges.
In addition to a video flyover, the client’s requirements were complemented by a comprehensive drone-based survey of the route.
A Lynx VTOL (Vertical Take Off and Landing), fixed-wing drone was chosen for the survey operation, covering over 2,000 linear kilometers and capturing 79,000 overlapping, high-definition images.
To ensure data accuracy, a Trimble R2 GNSS receiver was deployed alongside the drone.
In addition, a multirotor drone equipped with a 4K video camera was used to capture a video fly-through of the route.
The survey covered approximately 73 square kilometers, encompassing a corridor that ranged from 300 to 400 meters in width.
