National Highways' GIS and Research Team launched the RedLine Project to produce a digital representation of the SRN’s boundary.
However, manually digitising and evidencing each piece of land using multiple, unaligned datasets was a laborious task.
National Highways used OS MasterMap Topography Layer, accessible under the Public Sector Geospatial Agreement (PSGA) to create an Auto RedLine.
This automated process combines data to produce a continuous, categorised boundary dataset, providing an accurate and realistic view of the highway boundary, for operational decision-making.
With a clear and accurate picture of its total land footprint, National Highways can manage and maintain the network more easily – freeing up time, money, and resource for other projects, keeping goods and services flowing around the country, and, most importantly, making the network safer for people on the roads.
