Overview
![]()
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution. The acquired data, mission coverage and high revisit frequency provides for the generation of geoinformation at local, regional, national and international scales. The data is designed to be modified and adapted by users interested in thematic areas such as:

Data-Takes and DatastripsThe maximum continuous acquisition of an image from one SENTINEL-2 satellite is 15 000 km. The continuous acquisition is a "data-take", and the data-take forms the base of the subsequent product tree. If a data-take is acquired by two separate receiving stations, the data-take may be sub-divided into datastrips. When the satellite is switched from one observation mode to another, a datastrip may include several distinct observation segments separated by gaps of an integer number of granules. Figure 2 illustrates the data item classes in the SENTINEL-2 product levels and shows their relationship to associated levels of processing and generated products.
