Context
• DISC-UK DataShare (http://www.disc-uk.org/datashare.html)
• A JISC-funded collaborative project led by EDINA at the University
of Edinburgh, with the University of Oxford, the London School of
Economics (LSE) and the University of Southampton. Our central
aim is to develop a model for the deposit of research datasets in
institutional repositories (IRs).
• Alternative mechanisms for researchers to share data beyond the
IR.

Data Visualisation:
The set of techniques used to turn a set of data into visual insight.
It aims to give the data a meaningful representation by exploiting
the powerful discerning capabilities of the human eye*.

Spatial Data Visualisation
• Programmableweb - http://www.programmableweb.com/tag/mapping
- map or spatial mash-up ‘resource discovery tool’
• GeoCommons – http://geocommons.com/ - ‘brings intelligence to the GeoWeb,
unleashing tools and data’ (downloadable as CSV, KML, Shape)

SRON & KMNI
BODC
U.S. National Snow and Ice Data Center
USGS Earthquake Hazards Program
• UNHCR layer in Google Earth – mash together news, images, video,
statistical databases relating to refugees across the globe via the “Google Earth
Outreach programme” - http://www.unhcr.org/events/47f48dc92.html

• UCL Centre for Advanced Spatial Analysis http://www.casa.ucl.ac.uk/
• GeoVue – one of the 7 nodes of the National Centre for e-Social Science
set up to develop ‘new kinds of virtual urban environments’ (VUEs) through
which users can participate in furthering their understanding of cities
• Demonstrators –
• link publicly available datasets such as Population Census to non-proprietary
mapping e.g. visualising a neighbourhood's geodemographic profile using
different area classifications through Google Maps http://www.londonprofiler.org/
• Linking 2D and 3D map data to real-time pollution data using open
mapping utilities
•
Engage in other forms of collaboration e.g. Virtual London (via Second Life)

• …and there’s more
• John Hopkins University’s Interactive Map Tool
• Supports digital field assignments allowing users to create custom mashups using a
variety of digital media, text and data – http://www.cer.jhu/index.cfm?pageID=351
• Minnesota Interactive Internet Mapping Project
• A mapping application that provides maps and imagery similar to Google Maps – claims
to be data rich, interactive, secure, easy to use, have analytical capabilities http://maps.umn.edu/
• Research at Pompeu Fabra University, Barcelona
• Researchers mining spatial-temporal data provided by geotagged Flickr photos of urban
locations – http://www.giradin.org/fabien/tracing/
• Thematicmapping.org
• A project (initialised by a master's thesis in GIS at University of Edinburgh) to
investigate the use of geobrowsers for thematic mapping http://blog.thematicmapping.org/

Numeric Data Visualisation Tools:
•
•
•
•
‘Open’ ethos – anyone can upload/download or use data
Commercial Services embracing Web 2.0 business models
Collaborative
Easy to use
But …
•
•
•
Ephemeral nature of web
Not trusted repositories / archives
if it’s computer generated and looks good it must be right!

hosted by the Federal Statistical Office of Switzerland
• Eurostat Tables Graphs Maps (TGM) - an interactive user interface
to Eurostat data

Food for thought ….
• Are such utilities a flash in the pan or here to stay?
• Are they more appealing for researchers than institutional
repositories?
• Do they lack gravitas for academic purposes?
• Can/should institutions support the use of these tools?
• Do such ‘open data’ resources contribute to the ‘Global
Database’?
