A Package-Based Architecture for Customized GIS
Andrés Pazos, J. D. Poveda, Michael D. Gould · IGI Global eBooks · 2012
In this chapter we present a package-based component architecture for the specific deployment and maintenance of public sector applications, specifically corporate Geographical Information Systems (GIS). The three-tier architecture defines a group of server-side packages, a kernel and external packages, that are dynamically requested and assembled at execution time according to the needs of individual users to produce on demand customized GIS applications. An intermediate middleware layer handles user authentication and version control. In order to demonstrate the proposed architecture, a practical prototype has been implemented using Java WebStart. This prototype demonstrates the creation of several GIS client applications, with increasing levels of functionality, and based on free software packages.
