The Sri Lanka National Spatial Data Infrastructure (SL NSDI) is conceived as a national programme to harmonize, integrate and optimize the development and sharing of fundamental geographical and statistical information across all government agencies and institutions. The development of this programme is being carried out through a step-by-step, practical process that will establish a strategic and evolving framework for a long term SL NSDI, and provide coordination and support to the development of its various components through a carefully conceived and guided incremental process. It is recognized that this infrastructure can only be as strong as the community of agency stakeholders that comprise it, thus each component of the programme will seek to build on and leverage the many good works being carried out in many of the more progressive agencies in Sri Lanka, across all sectors. This programme is being sponsored in Sri Lanka by the Sri Lanka National Spatial Data Infrastructure (SL NSDI) and implemented by Information and Communication Technology Agency of Sri Lanka.
