Read a Sentinel-2 tile

  1. Download a complete Sentinel-2 tile from ESA Open Access Hub.
  2. Start SNAP Desktop
  3. File --> Open Product...) Browse to the compressed Sentinel-2 zip file. Open) or drag and drop the zip file from Windows File Explorer into the SNAP Product Explorer tab.
  4. Click on the plus sign of the file name in Product Explorer. Unfold Metadata and Bands.

Display a Sentinel-2 tile

  1. Mark the file name in the Product Explorer. Right click Open RGB Image Window). In the Profile drop-down list select Sentinel 2 MSI False Colour Infrared. OK)

Resampling

We resample the spatial resolution 20m bands to 10m.

  1. Raster --> Geometric Operations --> Resampling). Open the Resampling Parameters tab.
  2. Define size of resampled product: check by reference band from source product. Select B2 from drop down list. OK).
