=== Micha Silver ===
Working on a new GRASS addon: r.optram
[https://github.com/micha-silver/grass-addons/tree/grass8/src/raster/r.optram the repo on github]

02/06: Initialize main file ''r.optram.py''

includes these functions:
# ''getImgList()'' - get list of IMG_FILEs in a Sentinel 2 SAFE Directory
# ''cropToAOI()'' - Crop the images to the Area of Interest
# ''prepareSTR()'' - Convert SWIR to the SWIR Transformed Reflectance
# ''prepareVI()'' - Prepare the (user chosen) vegetation index

03/06:
# Split to three modules: '''r.optram.preprocess, r.optram, r.optram.soilmoisture'''
# new function: ''prepareTrapezoid()'' - to get wet-dry regression lines and slope, intercept values

04/06
# ''prepareTrapezoid()'' function completed.
# (Joined video conf with Roger Bivand on R-GRASS integration.)

05/06
Initialize third file/function: ''r.optram.soilmoisture.py''
# ''createSoilMoisture()'' - creates new GRASS raster for a single date
# Add documentation to modules
# (joined video conf with Nyall Dawson)

TODO list:
* Read Sentinel cloud mask and mask out cloud pixels in '''r.optram.preprocess'''
* large study areas or very long time series will create a big numpy table of variables (vegetation index and STR). A possible solution:
# Determine some "reasonable" maximum size for the numpy table, depending on computer resources.
# Extract a subset of pixels from each raster in the time series, such that the total table pixel values will not exceed that maximum
# The size of the subset will be set by ("reasonable" max / number of rasters in time series)
# Allow user to determine "reasonable" max.
* Currently this addon consists of three sub-modules. Consider to consolidate to one.
* Improve HTML documentation
