Open source resources¶

Tools¶

OpenEV
Application for viewing and analysing raster and vector geospatial data
RAT
RAdar Tools (or RAT) is an open source IDL SAR processing tool provided by the Technical University of Berlin. It provides various advanced SAR image processing tasks (SAR, PolSAR, PolInSAR & InSAR) and supports SAR SLCs and detected imagery of RADARSAT-1, JERS-1, ERS-1/2, and ALOS PALSAR.
NEST

The Next ESA SAR Toolbox (NEST) is a user friendly open source toolbox for reading, post-processing, analysing and visualising the large archive of data (from Level 1) from ESA SAR missions including ERS-1 & 2, ENVISAT and in the future Sentinel-1.

In addition, NEST supports handling of products from third party missions including JERS-1, ALOS PALSAR, TerraSAR-X, Radarsat-1 & 2 and COSMO-Skymed.

BEST

BESTGUI
BESTGUI is a Graphical User Interface (GUI) for BEST written in Python and GTK+. It allows you to easily generate parameters files for BEST and launch the processing from the GUI. BESTGUI aims to be an improved GUI front-end for UNIX platforms (it also run on WindowsTM), with a prettier look and feel and some useful additional features.
ASF tools

Converting and geocoding tools of the Alaska Satellite Facility (ASF):

MapReady

Software in the MapReady Remote Sensing Tool Kit accepts level 1 detected SAR data, single look complex SAR data, and optical data from ASF and some other facilities. It can terrain correct, geocode, and save to several common imagery formats including GeoTIFF.

Polarimetric decompositions can be applied to multi-pol SAR data. Other software included in the package are an image viewer, metadata viewer, a projection coordinate converter, and a variety of command line tools.

Convert to Vector
Convert to Vector is a small program made to transform point or scene information to various other formats that are compatible with external applications such as Google Earth, GIS software such as ArcGIS, text editors, and spreadsheets.
SAR Training Processor
The SAR Training Processor (STP) is a graphical tool written to assist in learning and teaching the flow of SAR processing.
BEAM
A toolbox for viewing, analyzing and processing of remote sensing data. Originally developed to facilitate the utilization of image data from Envisat’s optical instruments, BEAM now supports a growing number of other sensors such as MODIS, AVNIR, PRISM and CHRIS/Proba.
PolSARPro
The Polarimetric SAR Data Processing and Educational Tool aims to facilitate the accessibility and exploitation of multi-polarized SAR datasets including those from ESA Third Party Missions (ALOS PALSAR), Envisat ASAR Alternating Polarization mode products, RADARSAT-2 and TerraSAR-X.

InSAR tools¶

DORIS
Delft Object-oriented Radar Interferometric Software - InSAR/DInSAR processor.
StaMPS

StaMPS stands for “Stanford Method for Persistent Scatterers”. Although the original version was developed at Stanford University, subsequent development has taken place at the University of Iceland and Delft University of Technology.

The package is no longer limited to persistent scatterers, but also incorporates a small baseline and a combined time series method.

ADORE DORIS
ADORE stands for Automated DORIS Environment. It is developed at the University of Miami Geodesy Group, to help researchers generate interferograms with ease. Just like DORIS it is an open source project and it comes with the same license. ADORE can not do anything that DORIS doesn’t, it’s only a simplified user interface.
GIAnT

GIAnT is a suite of Python libraries and scripts that implement various published time-series InSAR algorithms in a common framework. GIAnT was developed for:

  • Rapid generation of time-series products from interferogram
  • Direct comparison of time-series InSAR products using different algorithms
  • Cal-Val for time-series InSAR

The toolbox currently includes implementations of SBAS, N-SBAS and MInTS algorithms. The toolbox also includes support for using PyAPS to correct stratified troposphere phase components and to use GPS solutions if available to correct for orbital errors.

PyAPS

PyAPS is a python module that estimates differential phase delay maps due to the stratified atmosphere for correcting radar interferograms. It is based on Delaypackage originally written by Romain Jolivet for estimating phase screens due to stratified atmosphere using ECMWF’s ERA Interim reanalysis.

PyAPS includes support for ERA Interim, NARR and MERRA weather models. PyAPS uses the humidity, pressure and temperature information from meteorological models to estimate the dry and wet components of the atmospheric delay.

Varres

Varres is a variable resolution interferogram sampler that implements a curvature-based quadtree like resampler for reducing unwrapped interferometric phase to a smaller subset of observations. Using the reduced set of observations which represent the non-redundant observations in an unwrapped interferogram in modelling significantly decreases computation cost. Moroever, it can reduce bias due to uneven distribution of coherent samples in the unwrapped interferogram.

The original matlab package has been extended to include support for using a predefined map for resampling and estimation of an approximate covariance matrix for the samples.

ROI_PAC
Repeat Orbit Interferometry PACkage by Caltech/Jet Propulsion Laboratory, mainly for interferometric SAR processing.
IDIOT

InSAR Deformation Inspection and Observation Tool (I.D.I.O.T.) is a software package for fully automatic generation of differential SAR interferograms from ENVISAT single look complex SAR data.

Its main purpose is to simplify as much as possible the generation of differential SAR interferograms, even for complete novices in SAR interferometry.

I.D.I.O.T. uses the freely available DEM of the SRTM mission to compensate for topography and can work with both the coarse header orbits or precise orbit information. All interferometric processing steps are implemented having maximum interferogram quality and precision in mind.
