The goal of this project is to create and deliver a web mapping componen= t for Market Maker built upon free and open source technologies. The compon= ent will utilize client-side AJAX-based tools and a service oriented archit= ecture (SOA) to provide a scalable and extensible system that will allow de= velopers to easily respond to software bugs and feature requests. The new a= rchitecture for the web mapping component will allow for a flexible softwar= e stack of technologies for delivering geospatial information from publicly= available map services such as Google, Yahoo and Bing, as well as privatel= y administered sources such ArcIMS. This architecture will allow new map se= rvices or technologies to be integrated into the system and made available = to the Market Maker community in a timely fashion. A PostGIS spatial databa= se will also be developed for the component to manage the geospatial inform= ation being delivered by the various web map services and provide spatial i= ndexing and spatial operations to improve the client's performance and allo= w for a wider variety of queries.
This component will be capable of serving as the primary mapping compone= nt in the Market Maker system and thus is prepared for the rapid growth and= evolution of Market Maker as part of a more comprehensive system redesign.=
In addition, how to replace the proposed component with current mapping = component will be explore in terms of transition scenarios, budgets, and pr= oject duration.
