Marketing campaign

To better advertise the capabilities of GRASS GIS and its friendly community, we plan a marketing campaign. Some ideas are

• (ideally) monthly blog post on the main site, with social media advertisements
• ask students of our courses to fix bugs, add examples to manuals or write small tutorials as assignments that we could then show off with
• pick some works of the students and create webinars or live streams
• ... add more

Ideas

• "feature of the month" with screenshots (use manual pages and Wiki material)
  • "Did you know that ... "
• advertise the mailing lists: purpose and where to subscribe
  • grass-user
  • grass-dev
  • grass-announce (a low traffic list)
• newcomer level technical articles about
  • new startup in GRASS GIS 8: why is it cool
  • single windows GUI settings
  • data import/registration
  • how to best generate COG files with r.out.gdal
  • from zero to hero
  • ...
• power user level technical articles about
  • invite folks to provide examples for manual pages
  • invite folks to translate messages in Transifex
  • ...
• dev level technical articles about
  • compiling the software -> point to grasswiki installation page
  • work done on removing compiler warnings: explain how that's done with compiler flag using
  • Python linting and formatting: teach black and flake8
  • C linting and formatting efforts: teach indentation script
  • ...
• edu related articles about
  • tutorials
  • curriculum (goal: enable academics to easier teach GRASS GIS)
  • ...
• present new add-ons and examples of workflows using them
• Nice tweet about ongoing code development: ​https://gitmemory.com/OSGeo/grass
• Twitter: identify more hashtags to widen up the potential followers
• ...

Twitter posts

Tangible Landscape and GRASS GIS for Geography Education (done)

Tangible Landscape and GRASS GIS were used to teach geography topics such as water flow and flooding phenomena to 11 yo students in a secondary school. How cool!! The Tangible Landscape system couples a physical model with its digital model in GRASS GIS via 3D scanning, geospatial processing, and projection. The main advantage of this tangible system is that children can interact with the physical model by hand and see the effects of changes to properties of the model or simulated landscape processes. They can then concentrate on spatial aspects and effects of changing landscape components. Students showed an improved understanding of the concept of contours and basic landforms, indicating that Tangible Landscape provides an easy-to-understand concept and teaching tool that improves the geospatial thinking of students. Add pics from the paper (fig 3 & 5) + link to the paper: ​https://link.springer.com/article/10.1007/s10639-021-10847-y Link to tangible modeling book (​https://doi.org/10.1007/978-3-319-89303-7)

Student's projects/work in the context of GRASS mini grants

Redesigning the map display status bar combo box into a new settings dialog (done) During GSoC 2021 Linda (twitter handle) proposed and implemented a simple prototype of Single-Window GUI. It looks really cool at first glance. Still, there are some shortcomings and missing features that need to be removed/implemented to provide the Single-Window GUI layout as an optional mode in upcoming GRASS version 8.2.0. In these couple of months, with the mentoring of Anna, Martin and Vaclav, Linda (twitter handle) will be working on the reorganization of the map display status bar towards a fully functional testable Single-Window GUI mode which addresses the map display window settings through a new dialog. Have a look at Linda's project and progress here: ​https://trac.osgeo.org/grass/wiki/wxGUIDevelopment/RedesigningStatusbar and also the latest relevant PRs therein. Testing and feedback is highly appreciated. We are really looking forward for the Single-Window GUI in full swing! Thanks Linda and her mentors for such great features! Space-Time Dataset Visualization and Improved Interactive Maps for grass.jupyter (done) During GSoC 2021, Caitlin (twitter handle) along with her mentors, created “grass.jupyter”, a package that improves the integration of GRASS GIS and Jupyter with a set of functions for displaying GRASS data in Jupyter Notebooks. In its current state, grass.jupyter allows users to create static visuals and simple interactive maps. In these couple of months, mentored by Vaclav, helena and Stefan, Caitlin (twitter handle) will be working on new additional features to allow Jupyter users to fully and easily access the power of GRASS Specifically, she'll be focused on: create a class for visualizing space time datasets allowing users to create interactive time-sliders and non-interactive animations such as GIFs improve the integration with #folium so that users can access all of its functionality by means of new grass-folium objects create a function to display vector attribute data in nicely-formatted #pandas or #GeoPandas tables Have a look at Caitlin's project and progress here: ​https://trac.osgeo.org/grass/wiki/GSoC/2021/JupyterAndGRASS/MiniGrant2022 and also test her contributions here: ​https://mybinder.org/v2/gh/chaedri/grass/Jupyter-Timeseries?urlpath=lab%2Ftree%2Fdoc%2Fnotebooks%2FTemporal.ipynb. Testing and feedback is highly appreciated. We are really looking forward for grass-jupyter in full swing! Thanks Caitlin and her mentors for such great features!

New rgrass version (done)

The #rstats-#grassgis interface is getting a lot of love lately!! A new version of rgrass is now on CRAN (Here RT with comment Roger's tweet: ​https://twitter.com/RogerBivand/status/1500158809691594761?s=20&t=pIF_ik5iqrWQPIz1iSOUkg) The rgrass package works in 2 main modes: users can start R in a running GRASS session or start a fresh GRASS session from R. In both cases, all GRASS spatial power can be used from R - extending what is already feasible in R-spatial alone, and all statistical and plotting power of R can be used with GRASS data. Win-win!! This new rgrass release will permit those using functions readRAST(), writeRAST(), readVECT() and writeVECT() to transition to the new read_RAST(), write_RAST(), read_VECT() and write_VECT(), which use SpatRaster and SpatVector objects defined in the terra package. terra objects may then be coerced to stars, raster and sp objects for rasters, and sf and sp objects for vector. The development details and contributors' inputs can be found at: ​https://github.com/rsbivand/rgrass/issues/42. Please test and report any issues at ​https://github.com/rsbivand/rgrass/issues. Also, don't be shy and help us document these new functions by adding vignettes in the package website: ​https://rsbivand.github.io/rgrass/ and in the GRASS wiki: ​https://grasswiki.osgeo.org/wiki/R_statistics. Thanks Roger, Robert and all contributors! (twitter handles here and a nice gif)
