Presentation Transcript

  1. Dr K R Murali Mohan, Ph.D Director/Scientist-F Department of Science & Technology Ministry of Science & Technology New Delhi National Spatial Data Infrastructure (NSDI-India)

  2. What is a Spatial Data Infrastructure (SDI)? “It is an INFRASTRUCTURE that provides a basis for spatial data discovery, evaluation and application for Macro & micro level planners, implementers, users and providers within all levels of government, the commercial sector, the non-profit sector, academia and by citizens in general.” --The SDI Cookbook

  3. Who needs access to coordinated geographic information? • Land Records Adjudication • Disaster Management • Transportation Management • Water, gas & electric planning • Public Protection • Defense • Natural Resource Management • Telecommunications Infrastructure • Economic Development • Civic Entrepreneurs • Local Bodies

  4. Components of a Spatial Data Infrastructure (SDI) • Policies & Institutional Arrangements (governance, data privacy & security, data sharing, cost recovery) • People (training, professional development, cooperation, outreach) • Data (digital base map, thematic, statistical, place names) • Technology (hardware, software, networks, databases, technical implementation plans)

  5. Why to build an SDI? • Build data once and use it many times for many applications • Integrate distributed providers of data: Cooperative governance • “Location-based management” • Share costs of data creation and maintenance • Support sustainable economic, social, and environmental development

  6. Best practices • Treat data as strategic, capital assets and public goods • Collaborate and Coordinate • Align roles, responsibilities and resources for data stewardship • Organize Effective and Efficient Production and Stewardship of Data • Pool and Leverage Investments

  7. The outcomes of an NSDI • The participant members (contributors and users) are known and can interact • Core and specialized map and data services are easily discoverable and accessible • Decision-makers and analysts have ready access to the right geo-information for input to analytical and visual models – indicators, models, trends, patterns

  8. Creating the motivation • Development of an SDI should be a voluntary and have long-term vision • Government roles may require both incentives and directives • Commercial and non-commercial participants should find SDI appealing as a market • The correct solution for NSDI must be defined by the community

  9. Discovery Access Processing Metadata Framework GEOdata Partnerships extend our capabilities Partnerships Services Standards

  10. Software interfaces (Implementation Specifications) OpenGIS Consortium Endorsed practices and specifications Other NSDIs NSDI National Standards ISO TC 211 Foundations for implementation. (Abstract standards) Content standards, Authority for data Roles of standards bodies

  11. Earthquakes Floods Landslides Cloud Bursts Tsunami Avalanche etc Pollution Water Quality Ground water depletion Vector borne Diseases Hunger, Poverty and malnutrition Crime Sex ratio SDI Applications

  12. Govt. of India Role in SDI development • Advanced Internet infrastructure design, establishing the backbone • IT Expertise • GOI has understood the importance of SDI and implementation

  13. NSDI Clearinghouse • Supports uniform, distributed search through a single user interface to all domestic metadata collections to find data and maps • A free advertising mechanism to provide world access to your holdings under the principle of “truth-in-labeling” • Search for spatial data through fields and full-text in the metadata and categorical browsing • Links through to full data access and online web mapping services, where available

  14. NSDI-India Management Structure • NSDI-Steering Committee • NSDI-Executive Committee • NSDI-Nodal Agencies & Nodal Officers • Sectoral Committees • NSDI-India Secretariat • CEO and officers

  15. NSDI-India Standards Framework • OGC • BIS • Meta Data Standards, content standards developed and working on unified data model etc

  16. Service Framework • WMS • WFS • WMTS • WCS • Security (authorisation and Authentication)

  17. Legal Framework • Value Addition • IPR • Patents • Non-repudiation • Accuracies • Ownership

  18. Policy Framework • National Data Sharing and Accessibility Policy (NDSAP) • VIGIL • State SDI’s

  19. Outreach • Training and capacity building • NIGTR, Center for Excellences (IIT’s) • Training for Asia Pacific countries • Open mind approach to share the experiences and hand holding

  20. Future directions-Convergence:GeoICT • A basic building block for E-Government • Shall focus on the use and re-use of data and services between government (G2G) and the citizen (G2C) • Involves all sectors (Central, state, local government, academia, commercial)
