Micha Silver
Working on a new GRASS addon: 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
Luís de Sousa
Work on GRASS add-on r.mblend
- Module is still maintained and fully functional in GRASS 8.2 (now included in the GRASS global add-ons repository)
- However was not longer producing correct results due to new behaviour in v.what.rast
- Solution identified, using inner buffer to interpolation area (PR #910)
- A small unit test suite was developed (PR #911)
Documentation

- Coordinate CMake PR, fix some bugs and make some progress (got a full build on UNIX environment). [1]
- r.mapcalc removed previous threading artifacts that are ineffective.
- r.mapcalc refactored global variables in preparation for threading work. (PR to come)
