Citizen Sensors

One type of sensor network is humans themselves or citizen sensors according to Goodchild (2007). Humans have five senses and should be good observers of their local environment. Local observers are closer to phenomena than the scientists. There are more of them than the scientists. Presumably the local observers can identify changes in their environment; they are able to investigate those changes, and quickly respond to those changing conditions, for instance by reporting them. These individuals should be able to provide info as or more accurate than science.
