DfT Element 2 funding – to improve asset
inventory data.
Public Accounts Committee – Fifteenth Report Maintaining Strategic Infrastructure : Roads September 2014
Highways Authorities criticised for not knowing enough about local road assets and 45 authorities were criticised for not having completed asset management plans (early 2014).
80% of an organisations data has a location
element. But do we really know where it is?
Gearing up for efficient highway delivery and funding – January 2014
Funding eligibility in 2015 - driven by efficiencies and good practice.

The highways sector must continue to generate ideas and tools to ensure its services meet challenging demands.Phil Brennan, Association for Public Service Excellence
Gearing up for efficient highway delivery and funding – January 2014
DfT encouraging local authorities to build up their asset inventory and analysis capabilities.

Common Practice Today
Lists• Often paper based• Sometimes disparate • Partial cross referencing• Limited spatial intelligence • Subjective interpretation• No visualisation
• Fully digitised datasets• Uniform open data formats• Unique ID for data integration• Fully geo-referenced in 3D• Imagery and overlay driven• Intuitive “StreetView” interface
Efficiency Drivers
![Page 8: Roads Stream Sarah Jones GI Manager LandScope Engineering](https://reader035.vdocuments.net/reader035/viewer/2022062423/5697bf991a28abf838c9164b/html5/thumbnails/8.jpg)
Common Practice Today
Legacy Data• Approximate locations • Some data duplications• Often limited capture processes
– Techniques and technology – Incomplete due to inadequate
resource provision
• Accurate positioning intelligence• Detailed and correct inventory• Mobile Mapping
– Rapid, accurate, no site visits– Scalable, repeatable, multiple in-
house extractions from single campaign
Efficiency Drivers

Common Practice Today
Data Maintenance • Often undefined leading to
data potentially being…– Out of date
– Unusable
– Unreliable
Data Maintenance • Planned approach efined leading
to potential data issues such as– Repeatable campaigns, repeatable
accuracies achieved– Highly intuitive interface, open
formats, system integration– Imagery providing “real world”
verification

Common Practice Today
Data Accessibility and Sharing• Often depts working in silo• Possible duplicated data• Data unavailable across systems• Some restrictions with mobile
and desktop data deployment
• Shared and combined data model• Update schedule – “only once”• Platform and format independent• Data available – desktop, browser,
tablet

with legacy systems• Issues feeding into existing
workflows
Integration and Interoperability• Remote serving cost efficiencies• Platform and format
