Benefits to both host and wider community include:

The Cardiff University research group will benefit by having new means to visualise and expose their data to a broader community and range of stakeholders. The EPSRC/RETROFIT participants and larger stakeholder group will benefit by improved access to the Cardiff research teams outputs and the facility to conduct critical appraisal of research outputs. Community and stakeholder interaction with the various scenarios will be explored through guided EPSRC workshops.

EDINA will benefit principally through gaining experience with temporal Web Map Services and implementation of the Memento framework. The groundwork for future temporal facilities on, for example, archival copies of the large scale Ordnance Survey database, will also help inform future directions for the Digimap services. Additionally, the groundwork will provide a prototype exemplar capable of being readily extended more broadly to existing JISC geo-infrastructure.

The Memento Development Group will benefit by the addition of a new use case – an explicitly geospatial one. Additionally, the project provides a means to explore the issues related to ‘web’ and ‘content’ time and thus provides a valuable contribution to the future development of Memento.

Overall we believe the broader community will benefit by the innovative adoption of both WMS-T and Memento. In isolation both of these technologies have specific communities to which they are of immediate interest. Taken together they provide a vehicle for innovation and also provide a means for technology exposure into ‘non-traditional’ community spaces – in the case of the ‘geo-community’ this brings Memento to the fore and in the case of Memento it provides a challenging new domain area – geospatial.

This project will build a stakeholder engagement tool visualising historic, current and future energy efficiency estimates at the level of individual buildings*. Researchers exploring and investigating policy options on possible future states of the built environment need a simple mechanism to visually analyse and compare outcomes of different scenarios of urban energy reduction policy.

This project will produce modelled estimates of building energy use for the period 1990-2050 for a sample geographic area in Cardiff, South Wales and provide a web based application that allows researchers, policy makers and other stakeholders the facility to explore varying spatio-temporal patterns of energy efficiency outcomes. We will also explore a novel usage of the Memento framework by enabling ‘time-travel’ both backwards (‘web-time’) and forwards (‘content-time’).

Further the work will provide insights into aspects of temporal modelling of the Ordnance Survey large scale geographic database, MasterMap. The latter will inform how adaptations to the JISC Digimap service might be best optimised to provide access to historic versions of this and similar resources.

Key deliverables:

  • A database of building-level energy efficiency coefficients for 2000-2050 for a large sample area within South East Wales
  • A database schema for exposing the model outputs via a WMS-T
  • A WMS delivering the data visualisations
  • A WMS-T allowing temporal navigation
  • Tile Cached versions of the above allowing direct URI mapping to resources
  • A Memento geo-Timegate and proxy allowing translation of Memento requests into WMS-T ones – Note: subsequently agreed to be outwith scope of project
  • A Web Client (OpenLayers based) allowing user interaction and visualisation of the modelled outputs under variable input scenarios
  • Potentially, demonstration of the outputs, visualised and temporally query-able in a Google Earth client
  • User needs requirements/ problem and issue refinement.

* A decision was most early in the project that in order to provide a more meaningful representation of the energy variables Output Area would be the geographic unit of analysis.
