Real-time condition data indicative of conditions is collected from at
least one sensor at a particular location or from a plurality of sensors
at different locations over time. The data collected from different
locations is time-synchronized to produce data indicative of conditions
at the different locations at one or more times. Real-time position data
indicative of the location(s) of the sensor(s) are also collected over
time. The collected real-time condition data are correlated with the
collected real-time position data to produce correlated data indicative
of conditions at the one or more locations over time. At least a portion
of the collected and correlated data is analyzed to determine conditions
at the one or more locations over time.
