Stack Processors

Read the document for each stack processor for details.

• stripmapStack
• topsStack
• alosStack

Installation

To use a stack processor 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
   • set environment variable $PATH_ALOSSTACK by doing: export PATH_ALOSSTACK=CODE_DIR/contrib/stack/alosStack to use the alosStack for processing a stack of ALOS-2 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.
