1. Go-Geo! The Go–Geo! Portal A service for those concerned about the 'where' as much as the 'what' JISC Conference 2005 Dr David Medyckyj-Scott Research and Geo-data Services Manager EDINA National Data Centre http://www.gogeo.ac.uk

2. Geospatial data – theres a lot of it about Geospatial data a class of data that describes the earth

4. Geospatial data – theres a lot of it about Geospatial data a class of data that describes the earth 80% of business and government data is geospatial vast quantities of geospatial data available in government, academia and business –e.g. Digimap: 300,000 data files downloaded in last 6 months various EU directives and legislation require such data to be made accessible by public bodies inc. universities and shared more widely geotechnology is one of the three most important emerging and evolving fields, along with nano- technology and biotechnology US Dept of Labour 2003

6. The vision - a GI Portal which… promotes greater awareness of geospatial data within tertiary education –increasing amounts of geospatial data being created –existence is not publicised –need to help make more (effective) use of these data promotes greater awareness of geospatial data within the wider GI community in the UK facilitates understanding of the problem space: provides access to geographically related resources a geographically-oriented access point to the JISC IE

7. Go-Geo! history developed collaboratively with UK Data Archive a long history… –2000-2001: scoping study establishment of a Z39.50 compliant resource discovery tool for geospatial data for UK academia –2002–2003: development of a demonstrator suitable for extension to full service and proof of concept * January 2003, an exit strategy produced –2003–2004: *develop portal to roll out a service *trial with user community *technical development *parallel metadata promotion initiative (UKDA)

8. Go-Geo! – History & current status JISC funding ceased at end of July 2004 EDINA took on running of Go-Geo! service for 1 year JISC have since funded –some development work (phase 4a) –a project to promote and encourage geospatial metadata creation within UK tertiary education (phase 4b) situation will be reviewed this August use of the portal is growing…

18. Technical highlights Searching using Z39.50, the portal undertakes simultaneous searching by cross searching a number of databases (catalogues) and resources support for GEO Profile –GEO servers must support the Bib-1 and GILS Attribute Sets to a limited extent indexes created by harvesting and parsing documents allows topic and geographic relevance ranking a WSRP portlet which can be plugged into other portals A geographic search capability interoperating with geoXwalk, a geographic semantic web service, means the different geography problem can be solved

20. Technical highlights (cont.) A Metadata Standard –a Tertiary Educational Profile for geospatial metadata description –based upon ISO19115 information metadata standard, –cross-mapped to a range of relevant standards –records retrieved from targets are mapped to the profile for display to users e.g. from DDI A Metadata Creation Tool –A XML based web application for creating, editing and managing versions of metadata records

21. Recent and ongoing developments a WSRP portlet which can be plugged into other portals exposed Go-Geo! as a virtual catalogue within the national, government funded, GIgateway service investigated extending the portal to be a e-science GRID portal for GI sciences now working on user customisation and investigating utility of enquiry organisational folders (EOFs)

23. Go-Geo! Phase 4b project 18 month (Feb 2004 - July 2006) initiative aims to promote and encourage geospatial metadata creation within UK tertiary education undertake workshops and promotional activities and co- ordinate metadata creation, collection and quality assurances carry out a pilot study with 4 universities to establish a business model for metadata creation and maintenance based on the use of Go-Geo! resources as local data management tools technical developments –implementation of an Open Geospatial Consortium (OGC) Catalogue server interface on to Go-Geo! to ensure compliance with the ISO 19115 Metadata standard –rollout of online metadata editor tool provide guidance to JISC for others areas in which metadata is an important resource

25. Data access mechanisms a link within the metadata record to an online ordering service user is taken to the data via a link to some online service –data extraction function e.g. UKBORDERS –interactive viewing clients e.g. Digimap the user may be directed to a repository from which the data can be extracted and downloaded the user may be able to automatically mine the data from a remote, online data source –data is delivered to some type of web client where it can visualised and possibly analysed Lets look at an example….

26. JISC Interoperability demonstrator project prove the feasibility of delivering geospatial data using OGC standards demonstrate ease of use and value added build support and enthusiasm for further development stimulate and advance further thinking, and identify major hurdles in full development

27. Project Outputs using a range of OGC/ISO 19000 based web services (WMS, WFS, WCS) and a basic annotation web service (XIMA) produce a series of demonstrator clients to illustrate –access to data –a teaching focussed use case (Metosat data in teaching weather forecasting) –a research focussed use case (based on dynamic image registration using web services) a report on the utility and issues surrounding implementation of open standards for geospatial data within the JISC IIE

31. Issues and challenges creation of metadata is still an issue but not as big as it once was we need to go beyond metadata to data access but problematic –policies and mechanisms required which promote open data sharing *formal geospatial data repositories or do we formalise the informal mechanisms? *is the data in a state that it can be shared? –digital rights and copyright a big worry looking for resources to add to Go-Geo! –majority of information within JISC IE is not geo-referenced and thus not searchable geographically JISC IIE interoperability standards GI interoperability standards sustainability and income streams
