Introduction
This case study explores how Avian Australia, a leading surveying and reality capture company, partnered with engineering firms to revolutionie the terrain mapping and contour generation processes. By leveraging advanced technology and expertise, Avian Australia has significantly streamlined surveying operations and delivered accurate topographical data in record time.
Client Background
Surveying larger land areas traditionally involves substantial time and effort. Surveyors using robotic total stations and GNSS rovers manually gather observations and draft contour maps, often requiring extensive time onsite. Avian Australia recognized the challenges faced by surveying firms and sought to provide a more efficient and accurate solution, whilst delivering the accuracy required.
Problem Statement
The problem was clear: traditional terrain mapping and contour generation methods were labor-intensive, time-consuming, and often required surveyors to traverse the entire property, even in challenging conditions. Surveyors needed a more efficient and reliable approach to deliver accurate topographical data to their clients.
Avian Australia’s Solution
Avian Australia emerged as a valuable partner for engineering and surveying firms, offering an innovative solution to expedite terrain mapping and contour generation. Key components of Avian Australia’s solution included:
- Leveraging their team of experienced surveyors who understood the appropriate methodology and conducted rigorous checks to ensure data accuracy.
- Employing advanced drone technology to reduce on-site surveying time and deliver contour maps efficiently.
- Utilising GNSS/GPS observations for geo-rectification of 3D terrain maps.
- Collaborating closely with engineers, surveying firms and clients to tailor survey plans to specific project needs.
Implementation
In a recent project, Avian Australia was tasked with creating a terrain map with contours for a property, which posed unique challenges due to a landslide and dense bush coverage. Their methodology involved strategically placing survey marks in accessible areas and using GNSS/GPS observations to generate a 3D terrain map. Additional contour maps with varying intervals were created from the point cloud data.
The project was executed seamlessly, with Avian Australia completing the on-site work within a day and the subsequent processing and quality control of terrain maps in just a few days.
Results
The results of Avian Australia’s solution were impressive:
✓ Surveyors were no longer required to traverse the entire property, significantly reducing on-site time and associated risks.
✓ The client received topographical data in both CAD and PDF formats, enhancing their ability to plan effectively.
✓ Aerial maps provided updated site information, which proved invaluable for planning purposes.
✓ Local councils received comprehensive contextual information, aiding in the approval of planning applications.
