The ROI_PAC wiki was attacked in 2013 by spambots which created over 100,000 fake user accounts. We have been forced to disable account creation. The contents of the Wiki have been transferred to this new server (on AWS cloud) operated by UNAVCO.

ROI_pac version 3.0.1 was released on 24 August 2009. This version has some improvements and bug fixes since version 3.0 that was released in 2007. Get it from Open Channel Foundation. See Installation for installation instructions and TestRoi for instructions on processing the test data.

See Patches page for fixes to v3.0 that are in the v3.0.1 release (and look here for new patches).

The UNAVCO InSAR: An introduction to Processing and Applications using ROI_pac and GIAnT short course for 2013 was held July 29-31 in Boulder, Colorado. See http://www.unavco.org/edu_outreach/short-courses/2013/insar-roi/insar-roi.html for details.

Some of the ROI_pac short course presentations from previous years are posted here.

Another ROI_pac Short Course was held September 1-3, 2010 in Istanbul, Turkey at the Istanbul Kultur University (IKU). Contact Dr. Elif SERTEL of Istanbul Technical University or YuriFialko for details.

A new page Suggestions for improvements has been added to discuss improvements that people would like to see in ROI_pac.

New pages on Offset Tracking and Preparing Data for Modeling were added.

See Envisat page for information on the October 2010-April 2012 "drifting phase" of Envisat, TerraSAR-X page for information on TerraSAR-X, and COSMO-SkyMed page for information on COSMO-SkyMed. New readers for both TerraSAR-X and COSMO-SkyMed data have been contributed by Walter Szeliga in ContribSoftware.
