providing national online services
for the UK tertiary education
and research community
EDINA geo-data strategy
• content development
– core directly referenced UK geography today and past
– non-UK core geographies
– environmental data for UK
• responding to users' needs in research and teaching
• centre of geo-spatial web delivery expertise
• contribute to development of DNER
– finding aids
– inter (co)-operating services
– development through partnership of teaching resources
• contribute to ‘joined up geography’ in national
context
EDINA geo-data services

UK Agricultural and
Horticultural Censuses
Future developments - content
• Aerial photography
– Cities Revealed data from GeoInformation Group
• OS Historical County Series maps
– raster images from OS/Landmark Information
Group
• CHEST OS sample data sets
Future developments - projects
• E-Lib Digimap.Plus project
– survey of digital map data needs
– changing landscape
• A geo-data browser for the UK HE community (JISC
5/99 funded)
– scoping study into the requirements of a geo-data portal and
Z39.50 compliant geo-data browser
• Geo-crosswalk (JISC 5/99 funded)
– a feasibility study into a British and Irish Gazetteer service
• MapScholar - Digimap New Tools (JISC 5/99 funded)
– enhancing the DNER for learning and teaching
– case studies, learning tools, ‘virtual placements’
What is geo-spatial data?
• data which has a
direct reference to
its position on the
surface of the
earth
• either latitude /
longitude
• or grid coordinates
• or …..
• data is often
textual
Spatial reference
Attributes
Visualising geo-spatial data
• spatial references
can be used to draw
a map from data
Digimap
• Digimap is a JISC-funded, web-based mapping service
• created & hosted by EDINA with support & training jointly
with MIMAS
• access to Ordnance Survey map data via easy-to-use, mapbased interface:
– creating maps on-screen
– printing high quality maps
– downloading map data
Teaching and learning use
• Geo-spatial issues
– maps in use in all disciplines
– mapping capability becoming more available in
mainstream office software
(e.g. Microsoft Excel, MapPoint)
– specialist software
• General issues
– Web and IT skills
– student-centred tool
User Community

Case studies on teaching use
• Case study 1
– GIS for the Environment module
– final year undergraduates
– outputs: layouts, thematic map and GIS analysis
exercise
– Digimap used as data source
• Case study 2
– Master's degree in History and Archaeology
– data used for terrain analysis, cost surfaces, feature
extraction
Case studies on teaching use
• Case study 3
– Ordnance Survey mapping project: objectives
– learn about the OS in general (i.e. its goals,
activities, products, customers) through web site
and literature through use of the Digimap service to
access OS products via computer.
– 1st year undergraduate exercise
• Case study 4
– Year 2 undergraduate course, Geology
– maps and remote sensing
– surface visualisation using Digital Terrain Models
Support issues
• supporting distributed and heterogeneous users
– user self-help
– service documentation
– support from institutional staff
• end-user training
– available through Site Representatives
– EDINA not resourced to run end-user training
– subject centre orientation / awareness ??
Data development
Ordnance Survey data
• Meridian product being re-launched in January 2001
– improved specification
– annual update cycle
• OS sample data
– currently available to academia
through separate CHEST deal
– wide range of products,
small number of tiles
– low-subscription access
to this data only

and 1:10,560, from the First
Series through to the Fourth
• based on Cassini Projections
• Digimap Project has maps of
Newcastle and Edinburgh
