Subject: RE: [emergency] CAP Visualization (was RE: CAP Developers' Forum...)
Kon,
We are implementing simple GIS capabilities here at Anteon. In particular,
we use Oracle Spatial on the backend to produce map views for the area
impacted by the broadcast incident. Oracle Spatial will convert the polygon
or circle Lat/Long data into a map. I am not sure how sophisticated your
application scenario is, ours is relatively straightforward. We use Oracle
to convert the Lat/Longs into clickable maps and State/County codes. Our
application code then generates census data reports that present
demographics about the affected geographic region and estimate the potential
impacts to people and structures.
We've built a CAP broker in Oracle OC4J 10G. The broker parses the CAP
broadcasts to identify messages relevant to our customer (FEMA) business
processes. We store the message in Oracle XML DB with a Receiver Method
(JMS/Message Driven Bean) and populate our incident software with relevant
data from the message content. The J2EE enterprise application executes the
Oracle Mapviewer component to generate the map display from the Oracle
Spatial db. When the broker identifies an appropriate message, notification
methods are executed that deliver email, mobile phone and PDA messages to
subscribers. Subscribers can then access their various applications to view
the incident event data.
