RoiPac
Our lab has installed ROI_PAC 3.0 for SAR and InSAR processing. Some detailed introductions and explainations will be followed soon. And also, you can get information about InSAR and ROI_PAC from the links below.

ROI_PAC
ROI_PAC is located at /usr/local/ROI_PAC_3_0, and there is also SAR data available for your test at /usr/local/TEST_DIR directory. More information about how to play with it will be updated soon.
Usually, there are three steps to finish Interferometry SAR processing with ROI_PAC.
Take the test data (/usr/local/TEST_DIR) for example to explain the processing.
First, compile some environment variable and path used by ROI_PCA. There is already a template file named SAR_CONFIG at /usr/local/ROI_PAC_3_0/ROI_PAC. Change the necessary commands, and then "source" in.
source SAR_CONFIG
Then, ingest the data. Go to the SAR data directory (/usr/local/TEST_DIR/930110 and /usr/local/TEST_DIR/950523), and ingest data respectively.
TEST_DIR/930110> make_raw.pl PRC SARLEADER1993011018252739T1Of1 930110 TEST_DIR/950523> make_raw.pl PRC SARLEADER1995052318253409T1Of1 950523
Note: Different SAR data format has different commands to ingest. For our case, they are ERS data, so "make_raw.pl" is used.
Last, data processing. Actually, there is a command "process_2pass.pl" can run all the steps after raw data ready. And the file "int.proc" in main directory (/usr/local/TEST_DIR) specifiles two scene directories (data and orbit) and other processing parameters for a given interferogram.
process_2pass.pl int.proc
And also, we can do it step by step.
process_2pass.pl int.proc [DoItFrom EndItAt]
DoItFrom = point in process.pl to start
EndItAt = point in process.pl to end
Can be: raw, roi_prep, orbbase, slcs, offsets, resamp, flatorb, full_res, filtered, make_mask, unwrapped, simulation, morph_sim,
redo_base or use_sim_base
EndItAt can also be synth_offset
