InSAR ISCE — InSAR Scientific Computing Environment is a flexible and extensible computing environment for geodetic image processing for Synthetic Aperture Radar (SAR), available to WInSAR members.

LIZARDTECH GeoViewer — Display MrSID imagery, raster imagery, LiDAR point clouds, and vector overlays in one standalone application.

PolSARPro — The Polarimetric SAR Data Processing and Educational Tool aims to facilitate the accessibility and exploitation of multi-polarized synthetic aperture radar (SAR) datasets.

SARViews — A fully automatic processing system that produces value-added products in support of monitoring natural disasters. The SARVIEWS processor is implemented in the Amazon Cloud and utilizes modern processing technology to generate geocoded and fully terrain corrected image time series, as well as interferometric SAR data over areas affected by natural disasters.

Sentinel-1 Toolbox — A collection of 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 and -2, and ENVISAT, as well as third-party synthetic aperture radar (SAR) data from ALOS PALSAR, TerraSAR-X, COSMO-SkyMed and RADARSAT-2. 

Worldview Quick Look Tool — This tool from NASA's EOSDIS provides the capability to interactively browse global, full-resolution satellite imagery and then download the underlying data. Most of the 100+ available products are updated within three hours of observation.


Commercial Tools

ENVI — ENVI provides advanced, user-friendly tools to read, explore, prepare, analyze and share information extracted from all types of imagery.

ERDAS IMAGINE — ERDAS IMAGINE performs advanced remote sensing analysis and spatial modeling to create new information.

GAMMA — The GAMMA SAR and Interferometry Software is a collection of programs that allows processing of SAR, interferometric SAR (InSAR) and differential interferometric SAR (DInSAR) data for airborne and spaceborne SAR systems.

Geomatica — Geomatica is a single, integrated software system for remote sensing and image processing.
