Reading a Sentinel-2 tile
- Download a complete Sentinel-2 tile from ESA Open Access Hub.
- Start SNAP Desktop
- 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.
- Click on the plus sign of the file name in Product Explorer. Unfold Metadata and Bands.
Displaying a Sentinel-2 tile
- 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.
- Raster --> Geometric Operations --> Resampling). Open the Resampling Parameters tab.
- Define size of resampled product: check by reference band from source product. Select B2 from drop down list. Run.
Subsetting
- Spatial subset
- Spectral subset
