Abstract

The Landmap Service provides web-based access to spatial data and learning materials for UK Higher Education (HE) and Further Education (FE). The Landmap Service has five key functions: 1) Spatial Data Provider – Implementing the use of Open Geospatial Consortium(OGC) standards for data delivery via Landmap Kaia and negotiating licensingagreements for the wider academic community with data suppliers. 2) Metadata Provider – Enhancing and improving metadata provision for Landmapdata collections and working towards the INSPIRE standard. 3) DeliveringE-learningContent–Identifyingavailablecontentaddressingtheuseofspatial data, standards and software from the wider spatial science community and providing these materials using a Creative Commons license through the Landmap Learning Zone.4) Outreach and Training – Widening the awareness of Landmap and establishing grounds to widen access to Landmap data resources through online surveys.5) Technological Innovation – Establishing linkages and collaborations with other spatial data services by providing interoperable OGC services.This paper explores the challenge of trying to build a ‘GeoKnowledge Community’ issues have been faced by Landmap for each of the five functionalities listed such as:Current data licenses restrict wider access to data collections The time and resources required to produce INSPIRE compliant metadata Developing and adapting content for e-learning using a pedagogic framework Achieving value-for-money when increasing awareness of Landmap resources through outreach and training activities for a variety of user groups e.g. students, librarians, lecturers and the wider community Technological challenges in creating linked data such as the need in the wider community to converge the Semantic Web and the Geo WebThere have been successes such as obtaining funding and support from the Joint Information Systems Committee (JISC) for the Metadata Enhancements Project which has enabled Landmap metadata to be further developed following ISO 19115 standards. The next step Landmap envisages is to progress the metadata work by Resource Description Framework (RDF) tagging a subsample of metadata to increase its discoverability as linked data.In collaboration with the University of Nottingham (Centre for Geospatial Science), JISC has funded the E-Learning for the Open Geospatial Community (ELOGeo) Project which will deliver open courses through the Landmap Learning Zone on Open Data, Open Standards and Open Software in the spatial science field. Such projects will help to achieve the goal of creating a ‘GeoKnowledge Community’ by enhancing community knowledge with no restrictions through access to high quality case study materials.The centralising of a free spatial data resource at Landmap has provided a unique service in the UK enabling a greater number of academic institutions (both large and small) to access spatial data which would be more expensive if purchased from spatial data suppliers individually.The technological infrastructure at Mimas (which hosts Landmap) allows the service to be in a good position strategically for maintaining OGC services, also using new technologies to increase discoverability and awareness of Landmap such as Linked Data, Web 3.0 and Catalog Service for the Web (CS-W). Mimas maintains high quality Relational DataBase Management Systems (RDBMS) such as Oracle 11g. Landmap is in the process of upgrading its service using Apache load balancer in order to give maximum performance as well as ensuring 100% service availability. All spatial data is managed and delivered using an enterprise solution called Erdas Apollo. Also Landmap is in the process of doing further enhancements on the web client ‘Landmap Kaia’ using the JavaEE and Hibernate framework.Landmap now provides a main access point to e-learning in the spatial science field from courses in image processing to developing 3D models in Google Sketch-up. The move to a Creative Commons licensing framework for the Learning Zone means that high quality learning resources will be available from Landmap on a global scale, for the whole community helping to build ‘GeoKnowlege’.
