Changes on the fetchOrbit.py to download orbit files from the new ESA website (#273) 
* Changes to fetchOrbit.py to download orbit files in the new ESA website

I've made changes to the fetchOrbit.py to download the files on the https://scihub.copernicus.eu/gnss/#/home. I've used the generic credentials to query and download the orbit files.

* Update fetchOrbit.py

* Make output path generic

I've used os.path.join on line no. 165 to make it more generic.

* Set the verify option to true

I've set the verify option to True to remove the warning regarding "Unverified HTTPS request".

* Changes to the download link of the fetchOrbit.py

The download link before uses the href link on the XML of the website. It was properly working right until yesterday when it didn't work properly.  

Instead I've edited the script to be consistent instead with the download link on the scihub copernicus GNSS website. I've tested it and it worked properly.

* Update fetchOrbit.py

Stack Processors

Read the document for each stack processor for details.

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.

References

Users who use the stack processors may refer to the following literatures:
