What resolution is Sentinel-2?
12-bit
The radiometric resolution of Sentinel-2 is 12-bit. This gives a potential range of brightness levels from 0 – 4 095.
What is Sentinel-2 L1C?
About Sentinel-2 L1C Data SENTINEL-2 is a European wide-swath, high-resolution, multi-spectral imaging mission. Its high-resolution optical images have many applications, including land monitoring, emergency response and security services assistance.

How do I stop cloud cover satellite images?
Methods of Removing Cloud Cover from Satellite Imagery [2] A more common approach today is using pixel sorting, where multiple images are utilized and images are selected that are not too dark (e.g., shadowing) or bright (i.e., cloud cover).
What is a cloud mask?
The cloud mask enables cloudy and cloud-free pixels to be identified. The mask includes both dense clouds and cirrus clouds with an indicator specifying the cloud type. Processing is performed with data sampled at 60 m spatial resolution for all spectral bands.
What is the spatial resolution of Sentinel 2?
Spatial and Spectral Resolutions. The surface area measured on the ground and represented by an individual pixel, is termed as the spatial resolution. For SENTINEL-2, there are three possible spatial resolutions (see Table 1).
How big are the bands of Sentinel 2?
There are 13 Sentinel 2 bands in total. Each band is 10, 20 or 60 meters in pixel size. Sentinel 2 consists of 2 satellites. First came Sentinel 2A which was launched in 2015. Next came Sentinel 2b in 2017. Two additional satellites (Sentinel 2C and 2D) are planned to launch in 2020 and 2021. This will make a total of four Sentinel-2 satellites.
What are the data formats for Sentinel 2?
A SENTINEL-2 product refers to a directory folder that contains a collection of information (Figure 1). It includes: a manifest.safe file which holds the general product information in XML. a preview image in JPEG2000 format. subfolders for measurement datasets including image data (granules/tiles) in GML-JPEG2000 format.
Who is the manufacturer of the Sentinel 2 satellite?
Sentinel-2 has been developed and is being operated by ESA, and the satellites were manufactured by a consortium led by Airbus DS.
