| Abstract | The National Spatial Data Infrastructure (NSDI) for Bhutan should provides geographic data and attributes, with sufficient documentation (metadata), a means to discover, visualize and evaluate the data and some method to provide access to geographic data which can be through catalogues and Web mapping. The infrastructure is framed to be coordinated and administered at local, regional, national and international scale. The guiding principle is the use of common conventions and technical agreement where smooth discovery, exchange and exploitation of spatial data are-possible for decision making process. The NSDI fundamental geographic data set, the core and non-core data are be modeled and shared in the designs of emerging ISO standards by following the rules for application schema, publishing a feature catalogue, and standardizing the encoding of the data. Thus it is necessary to be aware of ISO, OGC and GSDI framework initiatives, scopes and participation at sub-national, national, and international scale and reap the benefits through collaboration with them and other relevant partners. Metadata is a key ingredient in NSDI, in supporting the discovery, evaluation, and application of geographic data for the users. Metadata helps people who use geospatial data to find the data they need and determine how best to use the repository data. Thus, it is modeled to a set standard metadata system targeted at users needs. The NSDI is framed to implement Internet-based software that allows users to inventory, advertise and access metadata and associated geospatial information within a global framework of servers. It will help people to access and to discover data and web mapping services and then requesting and displaying maps from different servers. Due to the multiple producers and users of geospatial data there tends to be duplication and redundancy of data. Therefore, the main objective of the NSDI is to develop an awareness and implementation of efficient planning and management of the spatial data infrastructure without duplication and redundant results. The model is targeted for feature coding and standardization of GIS database where it will serve the most important aspect of exchange standardization for the users. Thus it is modeled for the standardization of the database inability for easy exchange of information for the users and allows integration of GIS databases with various software solutions and also enables the network access |
