Flood sensor data visualization for flood-response-headquaters

Hi folks!

I´m looking for a "piece of software" to visualize some flood/water level sensor data on a simple map and project it to a big screen in our central  flood-response-headquaters.

This data renderer should manage the following things/features:
 - display simple vector and raster layers which come from formats like Shape, GML, KML, GeoTIFF, and so on. (BTW: PostGIS and so on isn´t needed because we are not able to offer a distaster proof geodatabase environment)
 - fetch some sensor data from another (disaster proof because it´s the sensor network) ODBC Database Connection 
 - perhaps some simple navigation tools for zooming in and out and panning around
 - refresh the map display automagically every, let´s say, 10 seconds

I thought of a local install of UMN Mapserver and a simple but self refreshing Webclient which connects to the UMN on localhost, but perhaps you have much better ideas?

I´ll be grateful for every small idea, thanks a lot in advance.

best,

Jürgen Zornig
