Ideas for the meeting agenda
Collect ideas here :-)
Markus Neteler
- Improve QGIS-GRASS GIS integration; update of provider to GRASS GIS 8
 - GRASS GIS addons overview generator for entire GitHub (and more?) based on tag "grass-gis-addons"
 - Discuss about a 4th edition of "Open Source GIS: A GRASS GIS Approach"
 - message translation: Easy machine translation of messages in OSGeo-Weblate with DeepL API
- my tests with DeepL show that the quality is very good; average translation time of a user message shrinks to 15 seconds √
 - note: one needs to login to Weblate to see the "Automatic suggestion" button (using the OSGeo-ID)
 
 - Fix docs:
- Provide better explanation for radius parameter for r.resamp.filter: https://github.com/OSGeo/grass/issues/2569
 - improve v.clean docs
 
 
Vero
- All - think about GRASS GIS mission and vision: Where do we want to be as a project in 5 years time? What do we want to have? What do we want to be?
 - Participate in discussions about GRASS interfaces with QGIS and R (rgrass)
 - Discuss sponsoring
 - Student grant for (python) documentation?
 - Discuss about wiki clean-up/update (Anna was working on a list of pages)
 - Website enhancements: complete open PR's, meet Daniel Torres, new support item in main menu
 - Discuss State of GRASS presentation for FOSS4G 2023
 - i.landsat if time permits

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

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)
