Geographic information systems (GIS) are computer-based systems used to collect, store, and display data sets related to positions on the Earth’s surface.
One important use of GIS involves creating time-lapse photography that shows processes occurring over large areas and long periods of time. In time-lapse imagery, individual frames of visual data can be captured at a slower rate and then combined and viewed at a faster rate.
For example, data showing the movement of fluid in ocean currents or air currents help scientists better understand how moisture and heat energy move around the globe. These convection currents of air and water regulate local weather conditions and global climate patterns.
flowing movement of air within a larger body of air.
all weather conditions for a given location over a period of time.
movement of a fluid from a cool area to a warm area.
collection of data, usually presented in list form.
material that is able to flow and change shape.
any system for capturing, storing, checking, and displaying data related to positions on the Earth's surface.
a form of energy that is transferred by a difference in temperature
continuous, predictable, directional movement of seawater.
photographing of a slow and continuous process at regular intervals, for projection at a higher speed.
state of the atmosphere, including temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness.
