Approach towards an Expert Geoportal System

The creation and management of geospatial data is always tedious requires huge budget, time and manual efforts. Therefore, the future of several important services including location-based services and disaster information system, which need geospatial data remains a matter of concern. Expert geoportal system (EGPS) is a tool based on a sophisticated approach for providing diverse geospatial services to a naive user without creating its own database (i.e. geospatial database). EGPS avoids the unnecessary efforts of creating and managing a database, which not only requires enormous amount of money but also manual efforts. This paper presents a step-by-step approach for designing and developing a system that uses third party authorized data and web services for providing diverse geospatial services to the naive user without creating and managing its own database.
