Topographical Survey Using Mobile Mapping Technology - R150 Julianstown to Duleek

We recently embarked on a large project, conducting a detailed topographical survey along the R150 road between Julianstown and Duleek, Co. Meath. This survey is part of a proposed active travel scheme aimed at enhancing connectivity and promoting sustainable transportation in the region.

  • Location: R150 Julianstown to Duleek County Meath.
  • Scope: Topographical survey and Mobile mapping services.
  • Challenges: Quick turnaround required. Survey procured and delivered in less than 3 weeks.

Our Project Solutions

This project consisted of surveying a 8.5 km road corridor between Julianstown to Duleek along the R150 road. This is a fast moving road with a speed limit of 100 km/h in places. Using mobile mapping was the quickest and safest option to get the survey done to the same accuracy as normal surveying methods.

As part of the survey we also survey we also installed a survey control network for future use during the design and construction phase.

  • The road was safely and accurately captured using our Leica TRK100 mobile mapping system.
  • Off road services were verified using total station and GPS techniques.
  • Control points were installed every 200m using total station methods and then levelled to ensure the height accuracy met the project specification.
  • Project accuracies Ground – Horizontal accuracy of +/-10mm for hard detail such as buildings, roads and walls and +/-25 mm for soft detail such as vegetation and surface changes.  Vertical accuracy (levels) +/-10 mm for hard detail and +/- 40 mm accuracy for soft -detail.
  • The survey cost was around 60% lower than using conventional survey methods.
