Minimize NEST - next esa sar toolbox

nest logo

The Next ESA SAR Toolbox (NEST) is an ESA open source toolbox under the GNU GPL licence for reading, processing, analysing and visualising ESA (ERS-1/2, ENVISAT, SENTINEL-1) and other spaceborne* (TerraSAR-X, RADARSAT 1-2, COSMO-SkyMed, JERS-1, ALOS PALSAR) SAR data processed to Level-1 or higher.


NEST is now replaced with the Sentinel-1 Toolbox for all missions. Please visit the Sentinel Toolbox website for the latest software.
