Navan Abbeyland Aerial and Topographical Survey

Project overview

Aerial and ground survey of proposed new route for distributor road at Abbeyland, Navan, Co. Meath. The project consisted of carrying out a combined aerial and ground survey of the corridor and surrounding areas for planning and detailed design purposes.. The project was carried out and delivered over a 5 week period.

Project solution

Survey carried out using a variety of methods and technologies including Trimble UX5 HP UAV, Trimble TX8 Laser scanner, Trimble S6 Total Stations and Trimble R10 GNSS receivers.
Installation of ground control points for future use during construction surveyed using static GNSS methods and total station methods.
The aerial and ground survey of roads were combined to produce a seamless final product which was suitable for use in detailed design. In terms of accuracy, cost and time this solution is ideal for this type of road project.
The aerial survey was processed using the latest Trimble aerial survey processing software with vegetation and buildings removed to create an accurate DTM for design purposes.
The accuracy of ground survey data was +/- 5mm XYZ on hard surfaces and +/- 25mm of soft surfaces. The UAV data had an accuracy of +/- 50mm.
