== 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 "[https://github.com/topics/grass-gis-addons grass-gis-addons]"
* Discuss about a 4th edition of "Open Source GIS: A GRASS GIS Approach"
* message translation: Easy [https://docs.weblate.org/en/latest/user/translating.html#machine-translation machine translation] of messages in [https://weblate.osgeo.org/translate/grass-gis 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 {{done}}
** 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
* ...

  • i.svm.* cleanup and preparation for a review
  • A conceptual proposal for a new start up screen
  • Initial version of imagery signature management module i.signatures
  • Remove obsolete parts of locale README file

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:

  1. getImgList() - get list of IMG_FILEs in a Sentinel 2 SAFE Directory
  2. cropToAOI() - Crop the images to the Area of Interest
  3. prepareSTR() - Convert SWIR to the SWIR Transformed Reflectance
  4. prepareVI() - Prepare the (user chosen) vegetation index

03/06:

  1. Split to three modules: r.optram.preprocess, r.optram, r.optram.soilmoisture
  2. new function: prepareTrapezoid() - to get wet-dry regression lines and slope, intercept values


04/06

  1. prepareTrapezoid() function completed.
  2. (Joined video conf with Roger Bivand on R-GRASS integration.)

05/06 Initialize third file/function: r.optram.soilmoisture.py

  1. createSoilMoisture() - creates new GRASS raster for a single date
  2. Add documentation to modules
  3. (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:
  1. Determine some "reasonable" maximum size for the numpy table, depending on computer resources.
  2. Extract a subset of pixels from each raster in the time series, such that the total table pixel values will not exceed that maximum
  3. The size of the subset will be set by ("reasonable" max / number of rasters in time series)
  4. 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

  • Expanded instructions on Pre-commit (PR #3006)
  • Mini guidelines on unit tests for add-ons (PR #916)

Aaron Saw Min Sern

  • Fix bug to complete r.univar parallelization. PR
  • Investigate CMake progress in Windows. There still needs to be source code fixes to be port over to MSVC:
    • Variable Length Arrays (VLA) is not supported in MSVC (is optional in C99).
    • DLL export directives are required across dynamic library boundaries.
    • ...
  • 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.
