Wilson Pym May were contracted to provide a GIS and digitising service for Dorset County Council which involved digitising all of their current drainage data.
This case study is an example of the use of GIS, asset management, digitising and IT Services being used to provide an effective solution.
The problem faced by Dorset County Council was not that their system was not capable of storing the vast amount of drainage data but that much of the data had not been added to the current asset management system and was simply in hard copy format (such as paper maps and printed CAD drawings).
The second problem was that this data was not stored centrally but spread amongst stakeholders such as Private companies, Local Authorities, and Dorset County Council itself. Dorset County Council required one central database containing all of the information which could be shared across a network using Dorset Explorer and their existing Maintenance Management system.
After consultation between Dorset County Council and Wilson Pym May a new database structure was created in line with the needs of the client. It was based on the Highways Directive 43 and adapted to meet the exact needs of Dorset County Council.
Over 3,000 documents containing drainage information were then handed over to Wilson Pym May from a range of key stakeholders from across the county. One of the main sources of information being Section 38 agreements which were converted into PDF’s for easy access.
The GIS team then began digitising, quickly processing pipes, gullies, culverts, and other drainage items into the new database as well as moving and editing existing data. As the database developed ESRI ArcGIS applications were created to increase the speed of digitising through pre-set numbers and automatic values. Existing Asset Inventory data was also added and spatially referenced to the road network. All assets were also hyperlinked back to electronic copies of the data to allow immediate interrogation of the original data.
