UAV TOpography
Boyne Greenway, Topographical & Bathymetric Survey Case Study
Achieved 70% cost reduction and survey-grade accuracy (+10 mm) over a busy 1.5 km national road without any need for traffic management.
Location: N52 Clonmellon, Co. Westmeath
Scope:1.5 km Urban and Semi-Rural Road Survey
Core Challenge: Quick turnaround required at a competitive price on a busy national route.
Services Provided: Topographical Survey and Mobile Mapping services.
Mobile Mapping Advantage: The fastest and safest option to achieve required accuracy without the need for traffic management (TM).
The primary solution was the deployment of Mobile Mapping technology to completely eliminate site safety risks and costs associated with traditional ground surveys on a busy road.
| Challenge Solved | Mobile Mapping Advantage | Verification & Accuracy |
| Cost & Time | The project cost was approximately 70% lower than conventional methods. | Data capture was rapid using the Leica TRK100 system, facilitating the quick turnaround required. |
| Safety & Hassle | Mobile mapping was the quickest and safest option, ensuring no traffic management (TM) or road closures were needed on the busy N52. | The road was safely and accurately captured without risk to surveyors or traffic flow. |
| Accuracy Verification | Data accuracy was guaranteed to meet strict project specifications. | A survey control network was installed every 150m using total station methods and carefully levelled. Off-road services were also verified using total station and GPS techniques. |
Final Accuracy Results:
The final outputs were provided in familiar, usable formats, ready for immediate integration into the design team’s workflow:
