Fix Burst Loading in Estimate Range and Azimuth Misreg (#110)
* Fix burst loading in estimateAzimuthMisreg.py

Within the for loop that starts at line 82, looping through range(minBurst, maxBurst) misses the burst with the maximum burst number. In cases where only one burst in a swath is used, the script fails at line 90 when .getWidth() is called on an empty xml. This issue can be fixed by adding the line maxBurst = maxBurst + 1

* Fix burst loading in estimateRangeMisreg.py

Similar to estimateAzimuthMisreg.py, calling range(minBurst,maxBurst) at line 185 will lead to an empty list and the some bursts not being loaded unless line 181 is changed from maxBurst = maxBurst - 1 to maxBurst = maxBurst +1

Stack Processors

Read the document for each stack processor for details.

Installation

To use the TOPS or Stripmap stack processors you need to:

  1. Install ISCE as usual

  2. Depending on which stack processor you need to try, add the path of the folder containing the python scripts to your $PATH environment variable as follows:

    • add the full path of your contrib/stack/topsStack to $PATH to use the topsStack for processing a stack of Sentinel-1 TOPS data
    • add the full path of your contrib/stack/stripmapStack to $PATH to use the stripmapStack for processing a stack of StripMap data

Note: The stack processors do not show up in the install directory of your isce software. They can be found in the isce source directory.

Important Note:

There might be conflicts between topsStack and stripmapStack scripts (due to comman names of different scripts). Therefore users MUST only have the path of one stack processor in their $PATH environment at a time, to avoid conflicts between the two stack processors.
