Global Spatial Data Infrastructure (GSDI) Technical Working Group status Douglas Nebert GSDI Secretariat and U.S. Federal Geographic Data Committee

Technical Activities n Support for communities of practice n Training activities n Reference software assessment n Cookbook developments n Coordination with Standards Bodies n Technical Challenges

Communities of Practice n GSDI Secretariat has invested Staff support in coordination, consultation, deployment of enabling software for: –UNGIWG demonstration project –Geographic Information for Sustainable Development (GISD) Pilot in Africa –Clearinghouse for Afghanistan to begin

SDI Training GSDI Staff and TWG members have offered SDI awareness/training courses: n Eritrea n Zimbabwe n China n Geneva n Redlands, CA USA n Kenya n Japan n South Pacific n CODI (Ethiopia) n AfricaGIS (Nairobi) n GASSIA Workshop n South Africa n Mali n Ecuador n US-Canada (Denver) n Brazil

SDI Training materials n Training materials used in the sponsored workshops and outreach are available on the GSDI website n Follow-up with training recipients is ongoing n Participation in curriculum development is encouraged by you as volunteers

SDI Support Software n GSDI seeks to locate well-documented reference implementation software for distribution to accelerate SDI implementation: –Catalog Service software (Isite) –Metadata Collection Software (Enraemed) –Web Map Service software (MNmapserver) –Javascript OGC WMS Viewer (Multiviewer) –ESRI GSDI/Global Map Grant program n Seeking other resources to advertise on the website

Cookbook Status n Cookbook contributions coordinated from international volunteers by GSDI Secretariat n SDI Implementation Guide (Cookbook) published as Version 1.1, May English- Spanish - Chinese- Polish (in process) n Terminology (Chapter 10) in work by Australia

Regional recipes n Activity in Africa to develop examples for an African version of the Cookbook (UNECA, EIS-Africa, GSDI) n European case studies and chapter contributions are being developed (AGILE) n OGC is supporting creation of specific recipes for OpenGIS services by vendors and academic institutions

Interoperability Pages n GSDI Secretariat, with help from member experts is creating an interoperability section for the website –Summary and interpretation of current specifications and standards –Links to resource documents and discussions –Links to applications using standards

GSDI and Standards Advocacy OpenGIS Consortium, W3C Software interfaces (Implementation Specifications) ISO TC 211 Foundations for implementation. (Abstract standards) NationalStandards Content standards, Authority for data Endorsed practices and specification s SDI Other NSDIs Regional SDI Coordination

Coordination with Standards Bodies n GSDI is Class A Liaison with ISO TC 211 –Attended Lisbon and Bangkok Plenaries –Interested in collaboration in Outreach n OGC interest in supporting national and international communities of practice –Regional Pilots (Africa GISD) –Community Pilots

Technical Challenges n Integrating multiple standards and specifications together to create a system more than the Sum of the Parts n Communicating complex standards and designs in appropriate ways for different consumers n Developing authoritative online resources for national and international use

Education n Continue to develop “Big Picture” designs of how the standards and specifications work together in an SDI n Requirement to build a common set of educational materials (modules) for use to teach different audiences (policy makers and technicians) technical and policy-oriented content
