Tools

NameDescription
Sentinel-1 Toolbox (S1TBX)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. The toolbox includes tutorials, also posted here on the ASF website, in the form of documents and videos.
ESA Sentinel App, for iOS in App Store and Android on Google Play.Powerful visualization of Sentinel product availability. Track the satellites in real time over a 3D globe, see the last and next time they have been and will be over the user's location, and more.
PolSARproThe Polarimetric SAR Data Processing and Educational Tool facilitates the accessibility and exploitation of multi-polarised SAR datasets. A wide range of tutorials and comprehensive documentation provides a grounding in polarimetry and polarimetric interferometry necessary to stimulate research and development of scientific applications; the toolbox of processing functions offers users the capability to implement them.
Other ToolsOther tools include a radar altimetry toolbox (BRAT), a data browser capable of exploring many product types in their native form (Derby), and more.
