Abstract
Integrating GIS with Distributed Applications Using Dynamic Data-Sharing Mechanisms
Track: Application Development
Author(s): Robert Burnett, Spyridon Tzemos, LaMar Stoops
Effective integration of a stand-alone GIS (e.g., ArcView 3.x) into a complex distributed software application requires an efficient, reliable mechanism for passing data and function requests to and from the GIS component. This paper describes the use of dynamic data-sharing mechanisms to integrate GIS capability into a multi-jurisdictional distributed emergency management information system. These mechanisms include dynamic layer updates from spatial and attribute information shared via a distributed relational database across multiple sites; storage of private and shared "viewmarks" to facilitate consistent GIS views; and asynchronous inter-process communication using function queuing and a data sharing link library.
