Development and Implementation of Interoperable Secure SDI Model Using Open Source GIS

摘要

>It is observed that none of the academic institutes in India contributes for the development of SDI model at national level. Some of the developed models are not highly encouraging with respect to technical, organisational and institutional aspects. Non-availability of a standard functional SDI model based on SOA, Lack of technical interoperability and security aspects have also been a prime concern in SDI models using Open Source GIS (OSGIS). This article discusses appropriate application areas, i.e. the Education Sector, Geographical Indication and Mineral Resources Information Infrastructures to develop and implement the SDI model by a suitable adoption of OSS. The architecture of SOA-based interoperable and secure SDI models, which links the metadata server to database server, 3-tier interoperability and security framework with the help of OSGIS is developed and implemented.
