It provides an integrated viewer for reading, calibrating, post-processing and analysis of ESA (ERS 1&2, ENVISAT) and 3rd party (Radarsat2, TerraSarX, Alos Palsar, JERS) SAR level 1 data and higher. ESA has chosen to distribute the software as fully open source to allow the remote sensing community to easily develop new readers/writers and post-processors for SAR data with their NEST Java API. The software provides both a command line interface and GUI for all features including data conversion, graph processing, coregistration, multilooking, filtering, and band arithmetic."
