The satellite is equipped with an opto-electronic multispectral sensor for surveying with a sentinel-2 resolution of 10 to 60 m in the visible, near infrared (VNIR), and short-wave infrared (SWIR) spectral zones, including 13 spectral channels, which ensures the capture of differences in vegetation state, including temporal changes, and also minimizes impact on the quality of atmospheric photography The Sentinel-2 mission has the following key characteristics: Multi-spectral data with 13 bands in the visible, near infrared, and short wave infrared part of the spectrum Systematic global coverage of land surfaces from 56° S to 84° N, coastal waters, and all of the Mediterranean Sea Revisiting every 10 days under the same viewing angles
The Sentinel-2A mission carries the MutiSpectral Instrument (MSI), which measures the reflected solar spectral radiances in 13 spectral bands ranging from the visible to the shortwave infrared (SWIR) bands (Drusch et al., 2012) Due to the way Sentinel-2 products are structured, in particular because of the number of JPEG2000 files involved, zoom-out operations can be very slow for products made of many tiles. For interactive display, it can be useful to generate overviews (can be a slow operation by itself). This can be done with the gdaladdo utility on the subdataset name. The overview file is created next to the.

Sentinel-2 from European Space Agency (ESA) provides good spatial (20-60 m) and temporal (ﬁve days) resolutions for the visible spectrum, but lacks the Thermal Infrared (TIR) band . Recently, methods have been developed with the aim of taking advantage of the characteristics of both products (Landsat-8 and Sentinel-2), with efforts to generate harmonized time series of surface.
Keep in mind Sentinel-2 bands have finer pixel resolution. Because SR is a function of the SR conversion methods, TOA reflectance is a more pure comparison for the imagery (green and NIR [Landsat 8 band 5 and Sentinel-2 band 8a] have the same band center wavelength, while blue and red are similar). A comparison of SR based on the Landsat 8 and. Sentinel-2 Global Mosaic finally lives up to its name by offering products from the entire globe as of now!

Sentinel-2 is a multispectral satellite developed by the European Space Agency (ESA) regardless of spectral characteristics thereof; this function can be very useful for separating similar spectral signatures that differ only in one band, defining thresholds that include or exclude specific signatures. In fact, classes are correctly separated if the spectral ranges thereof are not.
The Sentinel-2 Short wave infrared (SWIR) composite (Red: Band 12, Green: Band 8, Blue: Band 4) lets us draw conclusions about water content in soil and plants, as water strongly reflects in SWIR. This tool allows the computation of synthetic Sentinel-2 spectra that form the frame for the subsequent data analysis. Most remote sensing applications require the use of specific band combinations and do not rely on single bands. The optimization is mainly driven by the spectral characteristics of vegetation constituents and minerals in the respective waveband regions and is performed. When we applied the physically based method to Sentinel-2's green band and compared the depths with Landsat 8 measurements, we found a slightly lower RMSE, but the Sentinel-2 depths were unrealistically high compared with Landsat 8 values, and so this method was excluded (Table 1; Fig. S2). We selected the physical method over the empirical one because the empirical method cannot be applied. images combining with Sentinel-2 and SPOT-6. This work consists of establishing an interferogram method of the main types of vegetation in order to achieve the coherence of a multi-temporal Sentinel-1 radar image series, in SLC format (C band, VV and VH polarization), between 2015 and 2016.
