What does a sensor web add to a decision support system?
” A sensor web can be described as a combination of individual sensors which are networked together, collectively taking on the shape of a web. The sensors may be of varying types (ie. temperature, level recorders, snow gauges, weight sensors, visual monitors – almost anything that generates a signal). Those that are land based, are often referred to as terrestrial sensors. However, satellite and airborne imaging sensors can also form part of a network and are simply called airborne sensors. Most if not all sensors today will be digital devices. Most will be able to provide instantaneous measurements for parameters for which they have been designed and configured for use. Some will be able to store information onboard for later interrogation and download, while others may transmit data instantly through hard-wired or wireless networks. Yet others may not be able to store data results, nor communicate results; in these cases the sensor is monitored immediately. Sensors are directly rela
