Script to calculate Sentinel-2 (A-B) view_zenith, view_azimuth, sun_zenith and sun_azimuth

Sentinel-2 Angle Bands

Generate Sentinel-2 Resampled Angle bands (Solar Azimuth, Solar Zenith, View Azimuth, View Zenith).

This script uses Sentinel-2 L1C products as input to generate angle bands (Solar Azimuth, Solar Zenith, View Azimuth and View Zenith). Originally the angles are provided as a 23x23 grid (5000 m resolution) in MTD_TL.xml file (Inside GRANULE folder). This script resample the angles through bilinear function to a 10 m spatial resolution.

Dependencies

• Numpy
• GDAL

Installing via Git

python3 -m pip install git+https://github.com/marujore/sentinel2_angle_bands

or

git clone https://github.com/marujore/sentinel2_angle_bands

Usage

import s2_angs

#You can indicate a .zip, a .SAFE or the MTD_TL.xml file
s2_angs.gen_s2_ang('/path/to/my/S2_file/S2B_MSIL1C_20191223T131239_N0208_R138_T23KMR_20191223T135458.zip')

Disclaimer

The script may not work on L2A products, since the MTD_TL.xml file is different from L1C.
