The National Spatial Data Infrastructure (NSDI) is one that shares, uses and integrates a wide range of spatial data for social, economic and environmental benefit and has been identified as one of the key initiatives identified under the Digital Economy of the Government of Sri Lanka. It is a platform that maintains spatial data intended to create a common environment where all stakeholders and the public can corporate with each other, access relevant data, make timely decisions as well as contribute in providing relevant data for others to use. This will enable data sharing, avoid duplication in data collection, increase efficiency and collaboration among organizations.
Currently, NSDI Phase I system has been developed which includes a National Map Portal, a Metadata Catalogue, the Website (www.nsdi.gov.lk) and Five Use Case Applications to demonstrate the functionalities of NSDI and its benefits. It allows users to discover, view and obtain spatial information online for a particular part of the country without needing to know the details of how the data is stored and maintained by independent organizations.
Twenty six government organizations including Survey Department, Disaster Management Centre, Department of Forest, Department of Wildlife, Urban Development Authority, Department of Archaeology, Department of Agriculture etc. have contributed with more than sixty five spatial data layers for the NSDI.
