Role of a Clearing House Server Infrastructure for GIS Interoperability

This paper discusses the development GIS interoperability infrastructure which allows end user to search, locate and finally work at the end with all available geo-spatial data without bothered too much by format differences. Rapid development of internet technology allows more spatial and tabular data available and accessible publicly. However, it has been identified those data can not be utilized directly due to the differences in data acquisition techniques, data definition and differences in their semantic meaning. This situation reveal the need of interoperable GIS to support seamless information sharing. From the whole frame work of the on going research there are four components to support the application of GIS interoperability. In this paper the discussion is focused on the architecture and the role of resources clearing house component (server) to facilitate end users to search, locate and retrieve the required meta data from different organization at different time and places. It allows to make further enquire about particular spatial data. The discussion on GIS Interoperability model as well as the development of architecture of the proposed clearing house server are given also a special emphases.
