Abstract: Public Geographic Information system (GIS) is a solution that automates the process of collecting community contributions of spatial data, cross-referenced to base maps. It provides the capabilities of analyzing such spatial data giving effective decision support information. On the other hand, the most important implementation models for GIS used recently are Client-Server and Software as a Service (SaaS). This paper focus on giving typical situation as a case study for exploring the advantages of SaaS implementation model over Client server one where public GIS services are implemented first as client server model and secondly when implemented as SaaS. In our new urban City state office, SaaS implementation achieved huge reduction on the total cost of ownership for users of public GIS solution rather than previous GIS Client-Server implementation. High level of cooperative collaboration between departments has been achieved (e.g. survey dept. , land use dept.). Achieved huge reduction on front-up cost required to start using the GIS solution (typically it costs 4.26% of the total front-up cost in case client-server model is used which was 214000USD), and reduction in maintenance /installation hours needed to fix a bug or install new feature across department rather than previous GIS Client Server implementation where the same maintenance /installation hours must be replicated to install new batch containing the fix for new feature. Hence, SaaS implementation model for public GIS overcomes Client Server model in many different aspects and increased the Return On Investment (ROI) value for public GIS solution as it empowers departments in state office to focus in delivering more spatial business’s value rather than being busy with having a dedicated data center to operate and manage separate installation of GIS software in client server model.
