NEST is a new free ESA toolbox with an integrated viewer for reading, calibration, post-processing and analysis of ESA and 3rd party SAR data starting from Level 1. Distributed as fully open source, NEST allows users to easily develop new readers and post-processors for SAR data by means of a Java Application Programming Interface (API). NEST is developed by Array Systems Computing Inc. under contract to ESA.
NEST 1C includes the following features:
* A Display and Analysis Tool (DAT) SAR data visualisation, analysis and processing.
* A Graph Processing Tool (GPT) for command line execution of batch processing chains.
* A rich collection of readers and writers with an abstracted internal representation to allow easy and efficient access to SAR data
* Convert data to COTS file formats for use with third-party software
* Create and process graphs
* Tiled image viewing and support for very large datasets
* Read, display and calibrate ENVISAT ASAR and ERS 1 & 2
* Provide statistics, quick-looks and ingest parts or entire datasets
* Coregister detected products
* Convert Slant Range to Ground Range
* Time domain mulitlooking
* Mean, Lee, Frost, Gamma Map Speckle Filtering
* ASAR WSS Debursting

* Image Filtering
* Third-party developers are able to extend software and add new readers, writers and operators.
Supported product formats include:
* ENVISAT ASAR
* ERS AMI 1 & 2 (CEOS & Envisat format from PGS and VMP)
* JERS SAR (CEOS format)
* Partial support for ALOS PALSAR and TerraSarX
