"""
worsica script for edge detection using opencv
Author: rjmartins
Script to run all the image processing,
This does not include running the topo-bath image generation
since it is only once made and should be manually done.
Args:
>1) ZIPFILE is the imageset name located
in the same folder as this script
>2) ROI-NAME_is a region of interest name
>3) ROI-POLYGON is a string with a WKT POLYGON definition.
>4 and 5) [now deprecated] BATHYMETRY-THRESHOLD and TOPOGRAPHY-THRESHOLD are threshold
values given for bath and topography during MNDWI filtering
>6) WI_THRESHOLD is a comma separate value string that defines the threshold filtering value for each water index
>7) WATER_INDEX is a comma separate value string that defines the chosen water indexes
Usage: ./worsica_sentinel_script_ut_coastal.py [ZIPFILE] [ROI-NAME] [ROI-POLYGON] [BATHYMETRY-THRESHOLD] [TOPOGRAPHY-THRESHOLD] [WI_THRESHOLD] [WATER_INDEX]
e.g: ./worsica_sentinel_script_ut_coastal.py S2A_MSIL2A_20181229T113501_N0211_R080_T29SMC_20181229T124502
