Realization of Component-Based GIS Application Framework

Increasing number of geodata producers and users have expressed the need for the integration of geodata from distributed information sources and for interoperable GISs (Stoimenov, 2002). The systems that own this data must be capable of interoperation with systems around them, in order to make access to this data to become feasible. The system also must deal with issues unique to geospatial data such as: translating data formats into a uniform transient data structure, consistent coordinate systems, cartographic projections and platform-dependent data representations, and retrieval of associated attributes and metadata (Levinsohn, 2000,Vckovsky, 1998). Integrating geodata from various sources increasingly becomes important because of growing environmental concerns, pressures on governments and businesses to perform more efficiently, and simply because of the existence of a rapidly growing body of useful geodata and geoprocessing tools (Buehler, 1998).
