ESA has developed free open source toolboxes for the scientific exploitation of Sentinel missions. They are funded through the "Scientific Exploitation of Operational Missions (SEOM)", a new program part of ESA's fourth period of the Earth Observation Envelope Programme (EOEP-4).
The toolboxes include functionalities of historical toolboxes developed over the last 10 years and also support a range of National and Third Party Missions. They were built to host new functionalities that might be developed by the scientific community in the future. In addition, the toolboxes are portable on a cloud infrastructure and will be used to train the next generation of scientists on how to exploit Sentinel multi-mission data.
- Sentinel-1 Toolbox (S1TBX)
The Sentinel-1 Toolbox (S1TBX) consists of a collection of processing tools, data product readers and writers and a display and analysis application to support the large archive of data from ESA SAR missions including Sentinel-1, ERS-1 & 2 and Envisat, as well as third party SAR data from ALOS PALSAR, TerraSAR-X, COSMO-SkyMed and RADARSAT-2.
- Sentinel-2 Toolbox (S2TBX)
The Sentinel-2 Toolbox consists of a rich set of visualisation, analysis and processing tools for the exploitation of MSI data from the Sentinel-2 mission. As a multi-mission remote sensing toolbox, S2TBX supports ESA missions Envisat (MERIS & AATSR) and, ERS (ATSR), as well as third party data from RapidEye, SPOT, MODIS (Aqua and Terra), Landsat (TM), ALOS (AVNIR & PRISM) and others. The various tools can be run from an intuitive desktop application or via a command-line interface.
- Sentinel-3 Toolbox (S3TBX)
The Sentinel-3 Toolbox is comprised of a set of visualisation, analysis and processing tools for the exploitation of OLCI and SLSTR data from the Sentinel-3 mission. As a multi-mission remote sensing toolbox, S3TBX supports 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.
- Atmospheric Toolbox
The Atmospheric Toolbox aims to provide scientists with tools for ingesting, processing, and analysing atmospheric remote sensing data. The toolbox consists of four main software components: CODA, HARP, VISAN, and QDOAS. Some of the data supported by the Toolbox are products from satellite instruments such as Tropomi (Sentinel-5P), ALADIN (Aeolus), GOME-2 (MetOp), and OMI (Aura). But the toolbox also supports model data such as CAMS and data from ground-based instruments like those provided by EVDC.
- Altimetry Toolbox
The Altimetry toolbox is able to read all altimetry data from official data centres, from ERS-1 and 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, Jason-2, Cryosat and Sentinel-3, from Sensor Geophysical Data Record to gridded merged data. It can also visualise results and do some processing and computations.
- Other Tools
ESA has developed free open source Toolboxes for the scientific exploitation of Envisat, ERS and Third Party Missions. Some of these 'historical tools' are: PolSARpro, CFI, ESOV, Derby and BRAT. The main functionalities of these toolboxes are now being included in the new Sentinel toolboxes.
