The European Space Agency (ESA) has released the Sentinel-2A orthorectified products.
Images are available for free at this link https://scihub.copernicus.eu/s2/ . Dozens of images are already available covering different parts of the world (acquired during the last few days), and in a few weeks the satellite should cover the whole world. In fact, Sentinel-2 is in the Ramp-Up phase that will bring data acquisition to its full capacity.
The following is a very interesting video by ESA Web-TV that illustrates the characteristics of this new satellite.
The following table illustrates the Sentinel-2 spectral bands.
|Sentinel-2 Bands||Central Wavelength [micrometers]||Resolution [meters]|
|Band 1 - Coastal aerosol||0.443||60|
|Band 2 - Blue||0.490||10|
|Band 3 - Green||0.560||10|
|Band 4 - Red||0.665||10|
|Band 5 - Vegetation Red Edge||0.705||20|
|Band 6 - Vegetation Red Edge||0.740||20|
|Band 7 - Vegetation Red Edge||0.783||20|
|Band 8 - NIR||0.842||10|
|Band 8A - Vegetation Red Edge||0.865||20|
|Band 9 - Water vapour||0.945||60|
|Band 10 - SWIR - Cirrus||1.375||60|
|Band 11 - SWIR||1.610||20|
|Band 12 - SWIR||2.190||20|
These images with 10m spatial resolution will be extremely useful for environmental monitoring and applications related to agriculture, forestry, or urban planning.
In the following weeks I am also going to update the Semi-Automatic Classification Plugin for QGIS in order to adapt the tools to the products of the Sentinel-2 routine phase.
