3. What is NSDI? The NSDI is an overarching framework for the existing agencies with the authority to mandate constituent agencies to commit their data sets and generate new data on the basis of user needs To provide a “ single window ” for spatial data access through digital technologies Ensure standardisation of data-sets Avoid duplication of data- sets Provide for inter-agency co- operation

4. The NSDI Vision National infrastructure for the availability of and access to organised spatial data Use of the infrastructure at Community, Local, State, Regional and National levels for sustained economic growth NSDI 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

20. Metadata Updation-Cases (1) Consider a geographic data provider generating vector mapping data for three Administrative areas (A, B and C). Initially the vector mapping was generated using a common series of paper maps, which were processed in the same way into a vector format. The bulk of the metadata for this initial data could be carried at a single level, (Dataset series). This metadata would describe the quality, citation, source, processing, of the data for the three administrative areas. So, the metadata is exclusively at Dataset Series level. Metadata entity set (OGC Compliant ) Identification Citation and responsible party Extent Constraints Data quality Maintenance Spatial representation Reference system Content Portrayal catalogue Distribution Metadata entity set (NSDI Standard ) NSDILayer NSDICategory NSDILayerEntity NSDILayerCatalouge NSDISpatFrameMap

21. Metadata Revision-Cases (2) A lternate vector mapping of Administrative area A (South West District) becomes available. The metadata would then be extended for Administrative area A, to describe the new quality date values. These values would supersede those given for the Dataset series, but only for Administrative area A. The metadata for B and C would remain unchanged. This new metadata would be recorded at Dataset level. Metadata entity set (OGC Compliant ) Dataset - Administrative area A Dataset Identification Citation and Responsible Party Extent Metadata entity set (NSDI Standard ) NSDILayer NSDILayerEntity

22. (3)Eventually further data becomes available for Administrative area A (South West District), with a complete re-survey of The road network. Again this implies new metadata for the affected feature types. This metadata would be carried at Feature type level for Administrative area A. All other metadata relating to other feature types remains unaffected. Only the Metadata for roads in Administrative area A is modified. This road metadata is recorded at Feature type level. Metadata Revision-Cases Metadata entity set (OGC Compliant ) Dataset – Administrative area A Dataset Identification Citation and Responsible Party Extent Feature type - Administrative area A - Road network Dataset Identification Citation and Responsible Party Metadata entity set (NSDI Standard ) NSDILayer NSDILayerEntity
