How many Spectral Bands have the Sentinel 2 Images?
/
The Sentinel 2 satellites have a Multi-Spectral Instrument (MSI) with 13 spectral bands that range from the visible range to the shortwave infrared (SWIR). Bands come in variable resolutions from 10 to 60 meter and their wavelenght is determined based on specific purposes.
This post is a part of a group of videos called "Working with Sentinel 2 Imagery on QGIS" that shows the complete procedure to download, represent and process Sentinel 2 images in QGIS, more information in this link:
