NSDI policies and data initiatives - Dr. P.S. Acharya
- 1. NSDI Initiative – Policies and Data Standards PS Acharya, CEO, NSDI NRDMS-NSDI Division, DST, New Delhi NeGD, DeitY organized Thematic Workshop on "Use of GIS in Informed Planning And Decision Making“ Indian Habitat Centre, Lodi Road, New Delhi 29 March 2016
- 2. NSDI Vision and objectives National infrastructure for the availability of and access to organized spatial data Use of the infrastructure at Community, Local, State, Regional and National levels for sustainable development Vision Objectives Develop and maintain standard digital collection of data Develop common solutions for Discovery, Access and Use of spatial data in response to the needs of diverse user groups Increase the awareness & understanding of the vision, concepts and benefits of the NSDI
- 3. Current Problems • Sheetwise storage of metadata as against feature data • No service metadata accessible (e.g. WMS/ WFS etc.) • Catalogue service unavailable • Querying on visualisation/ web map service absent • Content standard for ‘soil’ is available or getting developed on other themes but not in a machine- readable standard form (GML Application schema) • Metadata not accessible in machine readable form (XML) • Nodes for GIS Data Assets from providing agencies not operational (metadata search display) (Display of result of navigation query Using IndoorGML)
- 4. • National Geospatial Policy, National Survey Act, State SDI Policies, Empowered SOI Committee, Technical Committee on NATMO • Co-branded BIS standards, Geology/ Forest/ Soil Data Specifications • National Foundation Spatial Data WFS and 1:50K countrywide WMS through National Data Portal (data.gov.in) • Admin. Boundary data harmonization Committee – SOI, Census, NRSC, NIC, MoSPI, HARSAC • Smart City Data by NATMO as WMS/ WFS, Mahakashi Data (1:5K, 1:10K), CityGML/ IndoorGML • UniqueIDs for parcels and flat properties for DoLR • Data Registry Prototype • NSDI Road Map – NGIS Deliverables Recent Progress Outline as of March 2016
- 5. Policies/ Important Decisions • National Map Policy, 2005 • NSDI Resolution, 2006 • State Chief Secretaries Conference, Feb 2011 • National Remote Sensing Policy, 2011 • National Mirror Committee for ISO TC 211 by BIS • National Data Sharing & Accessibility Policy, 2012 • State Data Sharing Policies (Delhi, MP, Odisha) • National Geo-spatial Information Policy (being drafted)
- 6. NDSAP - Highlights • ‘Proactive’ instead of ‘reactive’ sharing • Mandatory sharing of all data generated through public funds except on national security considerations • Publication of ‘Exclusion or Negative List’ • Four Types of Accesses (open, automatic registered, authorised registered, restricted e.g. G2G)
- 8. End User/ Decision-maker (Stakeholders) Data Providers (Shareholders) User/ Web applications Bind Publish Find Catalogues, National Data Registry (NDR) Databases (Oracle Spatial, Shape files, DGN files, raster files etc.) Service-oriented Architecture
- 9. Difficulties in sharing data between databases • Different rules for object’s categorization and definition (semantic heterogeneity) • Different data models and data structures (schematic heterogeneity) • Data collection, processing, presentation in different standards/ methods, different GIS platforms (syntactic heterogeneity) • Different institutional constraints (data access, rights of use, costs etc.)
- 10. Approved ISO/ OGC Specifications deployed (Indicative) • Data Metadata (ISO 19115) (NSDI Metadata version 2.0) • Geography Markup Language (GML) (ISO 19136) • Web Feature Service (WFS) (ISO 19142) • Web Map Service (WMS) (ISO 19128) • Conceptual Schema Language (ISO 19103) • Rules for application schema (ISO 19109) • Catalogue Service on Web (CSW) • Style Layer Descriptor (SLD)
- 12. Different Tiers of Standards for GI Management (Source: UNGGIM Draft prepared by ISO, OGC, and IHO)
- 14. DGN file Pre-processing CSV file RDBMS Data Service Platform OGC-compliant WFS/ GML file Data updation (WFS/ GML planned) Re-engineering Process
