The Kerala State Spatial Data Infrastructure (KSDI) is an Internet based Geo-spatial Data Directory for the state that facilitates users of the system to share and explore data related to political and administrative boundaries, natural resources, transportation and infrastructure, demography, agro and socio economy etc., of the state. The KSDI has been established for the purpose of acquiring, processing, storing, distributing and improving utilization of spatial data, in line with the National Spatial Data Structure (NSDI) initiatives.
KSDI is a collection of technologies, policies and institutional arrangements to facilitate availability of and access to spatial data, acquired and held by different government Departments/agencies and organizations to a vast, diverse and ever growing community of users. Its four main components are Institutional Frameworks, Technical Standards, Fundamental Datasets and Clearing House Networks. It helps to provide geo-spatial data sharing at all levels of government, commercial sector, non-profit sector, and academia. KSDI, which is the nodal agency formed in the year 2011 for GIS related activities in the state, also provides a reliable and supporting environment to access geographically related information using a minimum set of standard practices, protocols and specifications. Following are the objectives of KSDI:
Develop and maintain standard digital collection of data
Develop web based Geoportal to improve utilization of geospatial data (sharing of data through internet) for planners, decision makers and public
Develop common solutions for discovery, access and use of spatial data in response to the needs of diverse user groups
Provide a gateway for spatial data generated by various agencies in the State
Increase awareness & understanding of the vision, concepts and benefits of the KSDI
Key benefits of the KSDI Project are:
Facilitates sharing of geospatial data and avoid its duplication to reduce cost of data
Build data once and use it many times for different applications
Access to quality information improves decision making by government agencies
Facilitates e-governance at all levels
Decision-makers and analysts can get ready access to the right geo-information for use in analytical and visual models
Supports sustainable economic, social, and environmental development
The Kerala Geoportal established in January, 2013 has been upgraded to Erdas Apollo 2016 Webserver with enhanced features. It supports Service Oriented Architecture (SOA) and interoperable Open Geospatial Consortium (OGC) Web Services with facility for data discovery, query, spatial and non‐spatial analysis etc. Kerala Geoportal will be the starting point and web gateway for spatial data generated by various agencies in the State.
National Spatial Data Infrastructure (NSDI)
National Spatial Data Infrastructure (NSDI) is a national endeavour that has come to be seen as the technology, policies, criteria, standards and people necessary to promote geo Spatial sharing throughout all levels of government, the private and non-profit sectors, and academia. It provides a base or structure of practices and relationships among data producers and users that facilitates data sharing and use. It is a set of actions and new ways of accessing, sharing and using geographic data that enables far more comprehensive analysis of data to help decision- makers choose the best course(s) of action.
The Metadata standard specifies the elements needed to support establishment of a NSDI Metadata and also for major uses of metadata: (1) to maintain a catalogue of a NSDI Organizations spatial data holdings (2) to provide information to users of the holdings and the catalog of information (3) to provide information needed to process and, investigate spatial data holdings for access by users (4) to standardize the exchange format of the spatial data. The standard defines the information required by a prospective user (1) to determine the availability of a set of spatial data, (2) to determine the compliance of a set of spatial data for an intended use, (3) to determine the means to access the set of geospatial data, and (4) to access the set of spatial data successfully.

Delhi Spatial Data Infrastructure portal that provides detailed information on the Capital's Overground and Underground utilities has been launched on 27 November 2009."The underground utilities comprising water, sewer, telephones, power lines etc. have been mapped for the first time using State-of-Art Technology. The availability of Underground utilities in digital form would enable the concerned line departments to undertake preventive maintenance programs as well as locate the fault in the underground utility with precision. Developed countries have been using Geo-Spatial Technology for long for enhancing transparency in the functioning of Government Departments. The common database will be made available to various Government Departments for Design, Planning, Execution and Monitoring of all infrastructure projects. This would help improve efficiency and productivity of all city services by reducing conflict of interest and cost of duplication of work.
