Abstract: A system(11) architecture, and method for creating, storing, managing, accessing, communicating and displaying command, control and management information, to include text documents, tables, static map data and geographically reference dynamic data for the management of incidents or events by distributed, ad-hoc groups are described herein. The static map data may include, for example, cartographic data in digital format such as terrain data or street data. The dynamic data may include text, documents, tables, icons, and other symbology that graphically represent current status information (e.g., the current location of an incident, a resource, or the status of a facility). The system (11) includes one or more client subsystems (16, 17, 18, 19) running purpose-built and/or conventional software applications that communicate with a server subsystem (11) and can independently request, receive, store, and subsequently display the static map data and/or the dynamic data in document, tabular or graphical form.
