ABSTRACT
Building on over two years of success in adapting geographic information
system (GIS), simulation, and Web service technologies to support the
planning needs of government agency coalitions, the Multi Agency Planning
(MAP) MITRE Sponsored Research (MSR) team is working to integrate these
technologies into a seamless Web service portal. Our approach is to
use a GIS Web service as a display interface for both simulation results
and operator status report information. We integrate a GIS Web service
display into an exercise control pane, and feed custom GIS display layers
with data from a metadata repository, which in turn is frequently updated
by either simulation results or field status reports. The field status
reports come from participants logged into a Web reporting service,
and we anticipate the use of real-time sensor, global positioning system
(GPS), and/or transponder based status data streams as automated sources
of updates. The simulation updates come through a Web service developed
in another MITRE research effort, called SimServer. We use existing
simulations to produce an event and movement log that SimServer plays
over the Internet to the MAP Workbench Metadata Server. We leverage
the ESRI Tracking Server utility to provide GIS update data streams
from the metadata repository as a Web service to thin SOGIS clients.
We provide SOGIS client as a pane of the MAP Workbench but it can also
be accessed directly. We hope to further evolve this capability in future
research to support simulation interaction and composition via the GIS
interface, and eventually to provide a simple simulation engine as a
web service.
