Satellite imagery

Definition

Satellite imagery refers to the images of the Earth collected by satellites orbiting the planet, capturing data on land, weather, and other environmental factors. This technology allows for the analysis of vast areas quickly and efficiently, making it crucial for understanding global changes. Satellite imagery is essential for monitoring environmental issues, assessing natural disasters, and advancing scientific research, particularly in fields like meteorology and earth sciences.

5 Must Know Facts For Your Next Test

1. Satellite imagery can be used to track deforestation, urban expansion, and the impact of climate change over time.
2. The resolution of satellite images varies widely; some can capture detailed views at a resolution of less than one meter, while others provide broader views with lower detail.
3. Satellite imagery played a vital role in disaster response efforts by providing real-time information about the extent of damage after events like hurricanes or earthquakes.
4. Multispectral satellite imagery can capture information across different wavelengths, which helps in identifying different types of vegetation and land cover.
5. Organizations use satellite imagery to gather data that supports medical research, such as monitoring air quality and its effects on public health.
