The sensor web is a macro-instrument comprised of spatially-distributed sensor platforms.These platforms or pods can be orbital or terrestrial,fixed or mobile.
In a sensor web, the indivisual pods communicate amoung themselves wirelessly or otherwise.The sensor web concept goes one step futher:the indivisual pods comprising a sensor web are not just elements that can communicate with one another;they are elements that must communicate with one another.
A sensor web is a single,autonomous, distributed instrument.It spreads collected data and processed information throughout its entire network.Information collected by a sensor web is spread everywhere.The sensor web processes its internal information,draws knowledge from it, and reacts to that knowledge.Pods can therefore combine data accross the sensor web to identify a moving front and dertemine its speed and direction, a task that a single point meassurement cannot accomplish.

The Sensor Web Vision
- Sensors will be web accessible
- Sensors and sensor data will be discoverable.
- Sensors will be self describing to humans and software.
- Most sensor observations will be aasily accessible in real time over the web.
- Standadized Web Services will exist for accessing sensor observations.
- Sensors will be capable of issuing alerts based on observations.
