ESA SNAP Sentinel Toolboxes
ESA SNAP contains the toolboxes to work with Sentinel-1, Sentinel-2 and Sentinel-3 data and also provides readers for others.
Sentinel-1 Toolbox (S1TBX) is able to work with Sentinel-1, ERS-1 & 2, ENVISAT and with third party SAR data of e.g. TerraSAR-X, RADARSAT-2 and others. The toolbox contains product readers, analysis applications and tools for calibration, speckle filtering, coregistration, orthorectification, mosaicking, data conversion, polarimetry and interferometry. The toolbox could be run from the command-line and also from a graphical user interface.
The Sentinel-2 Toolbox (S2TBX) contains Sentinel-2 and third-party product readers for RapidEye, SPOT, MODIS (Aqua and Terra), Landsat (TM) and others. It contains a processing tools for atmospheric correction, resampling, mosaicking and analysis tools (e.g. biophysical processor) for the exploitation of optical remote sensing data.
The Sentinel-3 Toolbox contains analysis and processing tools for Sentinel-3 OLCI and SLSTR data. It also supports the ESA missions Envisat (MERIS & AATSR), ERS (ATSR), SMOS as well as third party data from MODIS (Aqua and Terra), Landsat (TM), ALOS (AVNIR & PRISM) and others.
Sen2Cor
Sen2Cor is a processor for Sentinel-2 Level 2A product generation. It performs the atmospheric-, terrain and cirrus correction of Top-Of- Atmosphere Level 1C input data.

ORFEO Toolbox
ORFEO Toolbox (OTB) is open-source, all algorithms in the OTB are accesible via Python and QGIS and others.
it can process high resolution optical, multispectral and radar images at the terabyte scale

PolSARpro
PolSARpro (Polarimetric SAR data Processing and Education Toolbox) supports the scientific exploitation of polarimetric SAR data and is a tool for high-level education in radar polarimetry.
The current version of PolSARpro is 6.0 (Biomass Edition). The software contains a collection of well-known algorithms and tools, establishes a foundation for the exploitation of polarimetric techniques for scientific developments and stimulates research and applications developments using Pol-SAR, Pol-InSAR, Pol-TomoSAR and Pol-TimeSAR data.
The tool is a standalone application that performs end-to-end processing without needing other software.
PolSARpro supports the future ESA Biomass mission and can be used to handle and convert polarimetric data from a range of Third Party Missions:
- ALOS-1
- COSMO-SkyMed
- RADARSAT-2
- TerraSAR-X and TanDEM-X

EnMAP-Box
The EnMAP-Box is an QGIS plug-in (QGIS version 3.16 or higher) for processing remote sensing raster data, originally developed to support the hyperspectral satellite mission "EnMAP".
