Cambridge, UK, 29 March 2007: East Sussex County Council (ESCC) has achieved efficiency gains with 1Spatial. In order to exploit the full functionality of its recently purchased Exor Atlas Highway Management System, ESCC Highways department needed to improve the quality of its network data. ESCC needed to merge its National Street Gazatteer (NSG) Level 3 network with its Maintenance network and chose 1Spatial to carry out the project.
1Spatial first carried out a pilot project using their Radius StudioT product to assess the level of conformance between the two networks, or in other words whether the geometries of the NSG Level 3 matched those of the Maintenance network. Using rules defined by East Sussex, the pilot project showed that around 90% of the data could be automatically fixed. As a result, the successful flowline developed for the pilot project was rolled out to the entire dataset, allowing the two networks to be merged automatically.
ESCC sent 1Spatial their data, who then merged the NSG network with the Maintenance network in just 3 weeks. The data was then returned to the council, meaning that the Highways department was not inconvenienced during the merge. The remaining 10% of the data was outside the rigid tolerances set by the council and needed to be examined manually. The council now: –
Has a single new dataset which gives accurate network data as well as attribute information
Can exploit the full functionality and roll out its Exor Atlas Highway Management System
Can be confident in the reliability of their automated data analysis, and their related business decisions.
Dale Poore, Programme Manager, Highways Department at ESCC, commented:
“1Spatial have done an excellent job and taken our poor quality maintenance network data and combined this with good quality street data to give us a spatial network with around a 90% match. This has saved us months of resource intensive work and has helped maintain our programme to implement our Exor Atlas highway management system for which a spatial network is essential”.
Duncan Guthrie, Managing Director, 1Spatial added:
“At a time when public sector organisations are under increased pressure to produce efficiency gains, we are delighted to assist East Sussex with transforming their disparate network data into a single, accurate data set. This proof of concept project paves the way for similar data cleaning projects, and demonstrates 1Spatial’s commitment to providing successful and efficient services to the public sector.”
