Abstract
Taming the ArcIMS Multi-Service Viewer Track: Application Development Author(s): Fred Pieper, Dan Deneau The ArcIMS Multi-Service Viewer is one of the sample ArcIMS HTML viewers. It supports simultaneous integration of multiple ArcIMS image map services from multiple servers to render a composite map. The value of this "cascading map server" approach is in the potential for sharing data among multiple sites that maintain and administer their own ArcIMS map services without the need for duplicating data and services at a centralized location. Such an approach makes sense for projects or user communities that require cooperation among multiple organizations or multiple divisions within an organization that individually maintain and serve geospatial data. The sample Multi-Service Viewer is a good starting point for implementing this type of de-centralized ArcIMS deployment strategy. However, it is somewhat un-refined and cumbersome to work with. To overcome the "out of the box" limitations, incorporate some user session state management features, and generally make it easier to use and administer, the sample code has been substantially modified and enhanced. The focus of this presentation is to highlight the enhanced functionality that has been developed in customizing the Multi-Service Viewer and to explain some of the specific implementation techniques used.
