NEST (Next ESA SAR Toolbox)
The Next ESA SAR Toolbox (NEST) is an ESA open source toolbox under the GNU GPL license for reading, processing, analysing and visualising ESA (ERS-1/2, Envisat, Sentinel-1) and other spaceborne SAR data (TerraSAR-X, RADARSAT 1-2, COSMO-SkyMed, JERS-1, ALOS PALSAR) processed to Level-1 or higher. NEST 5.1 release is now freely available for download on the NEST website.
This update adds InSAR optimised coregistration, integrated phase unwrapping, and support for ERS/Envisat cross interferometry.
This may likely be the last update to NEST before its major evolution with the Sentinel-1 Toolbox release in September 2014.
