Sentinel-2
Sentinel-2 is a European Space Agency satellite constellation providing high-resolution optical imagery for land monitoring.
Sentinel-2 is a pair of European satellites that take pictures of Earth's land. These images are very detailed and help scientists and planners monitor changes on the ground.
For example, these satellites can track deforestation, map crop health, or observe urban development. This data is useful for understanding environmental changes and planning for the future.
Sentinel-2 is a constellation of two identical European Space Agency (ESA) Earth observation satellites. Each satellite carries a Multi-Spectral Instrument (MSI) that captures data in 13 spectral bands, offering a spatial resolution of 10, 20, or 60 meters depending on the band. The mission provides systematic global coverage of land surfaces and coastal areas with a revisit time of five days at the equator.
Sentinel-2 data is freely available and widely used for applications such as land cover mapping, agricultural monitoring, forest management, and disaster response. Its consistent data stream and spectral capabilities make it a valuable resource for environmental analysis and change detection.
This term is appearing in AI news because advanced AI models are being used to analyze the vast amounts of data collected by Sentinel-2. These AI systems can process the satellite imagery to identify patterns and make predictions related to environmental conditions, such as heat resilience in cities.
