Abstract
Geographic information technologies are rapidly transitioning from desktop solutions to Web and wireless services. New safety and security requirements now demand that spatial applications be highly scalable, reliable and secure as organizations deliver content services to hundreds, and thousands of users. In response, GIS vendors are retooling their products to better scale to these requirements, while enterprise IT infrastructure vendors are incorporating spatial capabilities into their database and enterprise applications. The next generation of GIS, if there is going to be one, will be realized as the use of spatially-enabled data and services become embedded into an organization's mainstream computing architecture. This paper highlights the emerging the software architecture necessary for deploying this new class of real-time location services.
