In this article Keynetix Technical Team Leader, James Slater, outlines the scale and challenges presented by our Highways Agency data management systems (HAGDMS and HADDMS) which we run in a joint venture with Mott MacDonald.
My name is James (Jimbo) Slater and I am a technical team leader at Keynetix ,currently undertaking development of the next phase of the Highways Agency Geotechnical and Drainage Asset Management Systems (HAGDMS / HADDMS).
This project is a joint venture with Mott MacDonald to build, maintain and update a web based GIS application used by over 1200 users including numerous asset and data managers, asset owners and many experts from the Geotechnical and Drainage worlds. Over 250 offices have access to HAGDMS and HADDMS including managing agents, international design and construction consultants, contractors and a number of regional HA offices.
The system is securely accessed by users live over the Internet. At my last count the system held over 50,000 geotechnical assets with at least 400,000 geotechnical Observations and in excess of 1,000,000 drainage assets and rising fast! The majority of assets are also linked to supplementary data held on the system such as attached documents including photos, PDFS, AGS Data, Scanned Reports and Digitised Drawings.
At the heart of the system is Autodesk Mapguide, a web based mapping engine which provides an interactive and visual display of all the spatial data along with masses of other reference and background mapping datasets from the Highways Agency, British Geological Society (BGS) and Environment Agency (EA).
We are currently working with over 150 Gigabytes of raster data including national coverage aerial photography and scanned and geo-referenced drawings. There is also over 50 Gigabytes of vector data including the OS MasterMap Topo Layer, ITN Roads, BGS 1-50k Geology mapping, detailed river network models, Contours and Digital Terrain Models. Mapping data also includes the geometry for over 2 million located vector assets!
Recent areas of work on the system include automated drainage asset reports measuring progress for data population and quality against Key Performance Indicators (KPIs) set by the HA. There has been the addition of a national flooding register, which allows users to record and digitise flood events online and also the latest addition of flooding hotspots on the network (in other words high risk areas that may be prone to flooding). Also along a similar theme, one of my favourite parts of the system is the drainage spill modeller. This allows a user to visualise (on a map) the flow of a spill on the road network and how it flows through the various drainage assets (pipes etc) to the outfalls.
One of the main development aims for the team is to provide users with tools to help improve the coverage, population, quality and accuracy of asset location and asset condition data, to aid the ongoing management of the HA network. This is done in many ways including advanced reporting tools, dynamic mapping displays, asset scoring and grading systems, data validation and checking routines, advanced querying and much more.
This is a demanding but rewarding project to work on, with tight deadlines and challenging quality assurance procedures. But there are also some nice juicy problems to solve which (can be) great fun, and the team here and at Mott McDonald work really well together to deliver more and more innovative solutions.
