Doris is a standalone program that can perform most common steps of the interferometric radar processing in a modular set up. Doris handles SLC (Single Look Complex) data to generate interferometric products, and can be used to georeference unwrapped products. For an example, see the DEM of Las Vegas, created from ENVISAT data. As phase unwrapper, the external SNAPHU software is recommended (follow the link below to download, and install separately).

Doris is quite robust for handling ERS and ENVISAT data, since these platforms are very stable, have precise orbits readily available, and the data are affordable. Native SLC data readers have been implemented for JERS, RADARSAT-1, ALOS and for the new generation sensors TSX, Radarsat-2 and COSMO-SkyMed data reading support is extended via 3rd party tool (gdal), and interferograms from SLC data of these sensors can be generated.

Moreover, if your SLC data are not in one of these known formats, (e.g., you focussed it yourself with your own SAR processor, such as ROI_PAC or GAMMA) Doris can in general be used for the interferometric processing when the required parameters are passed to the SLC result (metainfo) files.

Doris has been compiled on virtually all operating systems including HP (first developed on HP), SUN, Linux (all flavors, currently maintained), MS windows (running Cygwin), using a variety of compilers, such as aCC, g++, and icpc etc. For more information on the design of Doris, and installation, please refer to the manual.

Though the use of Doris is free, we encourage you to state that you are using it. You can do this by citing in your publications either:

And by using the Doris logo in (poster) presentations. Doris logo

Necessary downloads to obtain a full version of the Doris software are:

  1. The source code tar archive (Doris (incl. the re-usable C++ matrix class), bin utility scripts, SARtools, ENVISAT tools.
    download below. For installation instructions, see the INSTALL and README file in the distribution.
  2. Documentation tar archive (User's manual; Download below, or view it online.)
  3. Additional software (getorb, SNAPHU, GMT, gv, or ghostview
    install seperately; not strictly required but very useful. At least install snaphu and GMT. Recommended is the fftw library v3.0.1 as well. See links below.)
Also consider downloading some other utilities/testers:
  1. The DEOS Matlab InSAR tolbox. It contains scripts for simulation, visualization of the products of Doris, and for additional processing (trend removal, multilooking, etc.).
    contents insar toolbox contents demo toolbox contents fractal toolbox (Download below.)
  2. Testdata for Doris, to check if it installed ok and to familiarize yourself with the software. testfiles for big endian machines (HP etc.) (3.2MB), testfiles for little endian machines (Linux PC etc.) (1.4MB). this README file is also in the archive.
