Definition
Satellite imagery is a type of image that is captured by satellites orbiting the Earth. These images can be used to create detailed maps of the Earth's surface, to monitor changes in the environment, and to track weather patterns.
Satellites capture images of the Earth's surface using sensors that detect different wavelengths of light, including visible light, infrared, and ultraviolet. These sensors take images of the Earth's surface from different angles and at different times, allowing scientists to create composite images that show changes over time.
Satellite imagery can be used for a wide range of purposes, including:
- Environmental monitoring: Scientists can use satellite imagery to monitor changes in the Earth's environment, including deforestation, urbanization, and pollution.
- Weather forecasting: Meteorologists use satellite imagery to track weather patterns, including hurricanes, tornadoes, and other severe weather events.
- Mapping: Satellite imagery can be used to create detailed maps of the Earth's surface, including topography, land cover, and geological features.
- Agriculture: Farmers can use satellite imagery to monitor crop health, predict yields, and identify areas of the farm that require attention.
- Urban planning: City planners can use satellite imagery to monitor urban growth, identify areas of congestion, and plan for future development.
In short, satellite imagery is a valuable tool that allows scientists, meteorologists, farmers, and city planners to monitor and study the Earth's surface in a way that would not be possible with ground-based observation alone.
