Sentinel-2 Views

Sentinel-2 Level-1C imagery with on-the-fly renderings for visualization. This imagery layer pulls directly from the [Sentinel-2 on AWS] collection and is updated daily with new imagery. Sentinel-2 imagery can be applied across a number of industries, scientific disciplines, and management practices. Some applications include, but are not limited to, land cover and environmental monitoring, climate change, deforestation, disaster and emergency management, national security, plant health and precision agriculture, forest monitoring, watershed analysis and runoff predictions, land-use planning, tracking urban expansion, highlighting burned areas and estimating fire severity. Geographic Coverage * Global * Continental land masses from 65.4° South to 72.1° North, with these special guidelines: * All coastal waters up to 20 km from the shore * All islands greater than 100 km2 * All EU islands * All closed seas (e.g. Caspian Sea) * The Mediterranean Sea Temporal Coverage * This layer includes a rolling collection of Sentinel-2 imagery acquired within the past 14 months. * This layer is updated daily with new imagery. * The revisit time for each point on Earth is every 5 days. * The number of images available will vary depending on location. Product Level * This service provides Level-1C Top of Atmosphere imagery. * Alternatively, [Sentinel-2 Level-2A] is also available. Image Selection/Filtering * The most recent and cloud free images are displayed by default. * Any image available within the past 14 months can be displayed via custom filtering. * Filtering can be done based on attributes such as Acquisition Date, Estimated Cloud Cover, and Tile ID. * Tile_ID is computed as [year][month][day]T[hours][minutes][seconds]_[UTMcode][latitudeband][square]_[sequence].[ More…] Visual Rendering * Default rendering is Natural Color (bands 4,3,2) with Dynamic Range Adjustment (DRA). * The DRA version of each layer enables visualization of the full dynamic range of the images. * Rendering (or display) of band combinations and calculated indices is done on-the-fly from the source images via Raster Functions. * Various pre-defined Raster Functions can be selected or custom functions created. * Available renderings include: [Agriculture with DRA],[ Bathymetric with DRA],[ Color-Infrared with DRA],[ Natural Color with DRA], [Short-wave Infrared with DRA], [Geology with DRA], [NDMI Colorized], [Normalized Difference Built-Up Index (NDBI)], [NDWI Raw], [NDWI - with VRE Raw], [NDVI – with VRE Raw (NDRE)],[ NDVI - VRE only Raw], [NDVI Raw], [Normalized Burn Ratio], [NDVI Colormap].

Data Source Sentinel-2 imagery is the result of close collaboration between the (European Space Agency) ESA, the European Commission and USGS. Data is hosted by the Amazon Web Services as part of their [Registry of Open Data]. Users can access the imagery from[ Sentinel-2 on AWS], or alternatively access [EarthExplorer] or the [Copernicus Data Space Ecosystem ]to download the scenes.
