gmtsar

InSAR processing system based on Generic Mapping Tools - metapackage

Description

GMTSAR is an open source Interferometric Synthetic Aperture RADAR (InSAR) processing system designed for users familiar with Generic Mapping Tools (GMT).

The code is written in C and will compile on any computer where GMT and NETCDF are installed.

The system has three main components:

* a preprocessor for each satellite data type (ERS-1/2, Envisat,

ALOS-1, TerraSAR-X, COSMO-SkyMed, Radarsat-2, Sentinel-1A/B,

and ALOS-2) to convert the native format and orbital information

into a generic format;

* an InSAR processor to focus and align stacks of images, map

topography into phase, and form the complex interferogram;

* a postprocessor, mostly based on GMT, to filter the interferogram

and construct interferometric products of phase, coherence,

phase gradient, and line-of sight displacement in both radar and

geographic coordinates.

GMT is used to display all the products as pdf files and KML images for Google Earth. A set of shell scripts has been developed for standard 2-pass processing as well as geometric image alignment for stacking and time series.
