Sentinel-2 imagery

Multispectral data

https://sentinel.esa.int/web/sentinel/missions/sentinel-2

Sentinel-2 is a European wide-swath, high-resolution, multi-spectral imaging mission. and carries an optical instrument payload that samples 13 spectral bands: four bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution.

The twin satellites of Sentinel-2 provides continuity of SPOT and LANDSAT-type image data, contribute to ongoing multispectral observations and benefit Copernicus services and applications such as land management, agriculture and forestry, disaster control, humanitarian relief operations, risk mapping and security concerns.

The mission objectives are to provide: (a) systematic global acquisitions of high-resolution, multispectral images allied to a high revisit frequency; (b) continuity of multi-spectral imagery provided by the SPOT series of satellites and the USGS LANDSAT Thematic Mapper instrument and (c) observation data for the next generation of operational products, such as land-cover maps, land-change detection maps and geophysical variables.
