* have been working on developing a workflow-tool tutorial template that facilitates GRASS learners who tend to 'jump in' or have a 'choose your own adventure' approach to learning GRASS (i.e., want to use their data for their study area for their objective from the start). The structure of the tutorial template is a concise, basic, general description/instructions of the workflow with optional links to pertinent explanatory/deeper dive content (e.g., plain language explainers of the tool, options, defaults, etc.) in a variety of formats (e.g., captioned images, short tool demo videos (30 sec to 2 min)) in addition to the more comprehensive resources available (e.g. documentation, examples, tutorials). The main motivation for this approach is to help new and occasional GRASS users avoid some of the common pitfalls and to learn how to find workarounds for some of the unanticipated challenges they may encounter with their specific datasets or use cases so that they can learn as they go. Another motivation for this approach is to facilitate the translation, extension, and updating of workflow tutorials by the community over time (e.g., providing audio and closed captioning for one of the tool-demo videos in another language, replacing an outdated GUI demo with one for the current release, or incorporating a new add-on as an option in the workflow).

* my focus this week is on developing a draft/test tutorial (in Quarto) for a standard hydrological modelling workflow that begins with the crucial pre-work of how to figure out the appropriate project/location, etc. as well as considerations of some of the downstream impacts of resolution, extent, region etc. It may not be ready for sharing by the end of the week, but suggestions and advice are welcomed in advance.

19 May
* discussed a novice user issue with 'moving' vector data from one location to another with Vero and learned a neat GUI option
* revised and added workflow tutorial text

=== Shonil Sateesh Bhide | NC State University ===

* CI optimization

=== Huidae Cho | New Mexico State University ===

* CMake, conda, CI, Mentoring

=== Edouard Choinière ===

* Quick ideas, way too much for a week: Helping others (may take a reasonable part of the time), managing CI, setting up localization template updating workflow, backporting tool? Pytest/coverage improvements? Discuss and design other projects, to work on during the year. Open to change on other priorities once there, anything that is useful. Maybe make a little progress on high dpi GUI, especially on Windows.

* Weekend before sprint:
** Clear up Renovate PRs to not use CI time during the sprint, reviewing and merging: [https://github.com/OSGeo/grass/pull/5664 #5664], [https://github.com/OSGeo/grass/pull/5665 #5665], [https://github.com/OSGeo/grass/pull/5666 #5666], [https://github.com/OSGeo/grass/pull/5667 #5667], [https://github.com/OSGeo/grass/pull/5668 #5668]

AND- Working on tutorial for Windows users to install a WSL2 Linux environment running Ubuntu 22.04LTS. Creates a conda environment with wxpython, then uses WSL2 to install GRASS from unstable repo without requiring OSGeo installer. Fast, minimal install. Preserves all the goofy windows python paths that get all tangled up with grass sometimes, and isolated distro can be completely removed if needed. Once set up it does not need special network routing through vpn. (For other uses that always wanted a more native feel to their grass instance!)

* have been working on developing a workflow-tool tutorial template that facilitates GRASS learners who tend to 'jump in' or have a 'choose your own adventure' approach to learning GRASS (i.e., want to use their data for their study area for their objective from the start). The structure of the tutorial template is a concise, basic, general description/instructions of the workflow with optional links to pertinent explanatory/deeper dive content (e.g., plain language explainers of the tool, options, defaults, etc.) in a variety of formats (e.g., captioned images, short tool demo videos (30 sec to 2 min)) in addition to the more comprehensive resources available (e.g. documentation, examples, tutorials). The main motivation for this approach is to help new and occasional GRASS users avoid some of the common pitfalls and to learn how to find workarounds for some of the unanticipated challenges they may encounter with their specific datasets or use cases so that they can learn as they go. Another motivation for this approach is to facilitate the translation, extension, and updating of workflow tutorials by the community over time (e.g., providing audio and closed captioning for one of the tool-demo videos in another language, replacing an outdated GUI demo with one for the current release, or incorporating a new add-on as an option in the workflow).

* my focus this week is on developing a draft/test tutorial (in Quarto) for a standard hydrological modelling workflow that begins with the crucial pre-work of how to figure out the appropriate project/location, etc. as well as considerations of some of the downstream impacts of resolution, extent, region etc. It may not be ready for sharing by the end of the week, but suggestions and advice are welcomed in advance.

19 May
* discussed a novice user issue with 'moving' vector data from one location to another with Vero and learned a neat GUI option
* revised and added workflow tutorial text

=== Shonil Sateesh Bhide | NC State University ===

* CI optimization

=== Huidae Cho | New Mexico State University ===

* CMake, conda, CI, Mentoring

=== Edouard Choinière ===

* Quick ideas, way too much for a week: Helping others (may take a reasonable part of the time), managing CI, setting up localization template updating workflow, backporting tool? Pytest/coverage improvements? Discuss and design other projects, to work on during the year. Open to change on other priorities once there, anything that is useful. Maybe make a little progress on high dpi GUI, especially on Windows.

* Weekend before sprint:
** Clear up Renovate PRs to not use CI time during the sprint, reviewing and merging: [https://github.com/OSGeo/grass/pull/5664 #5664], [https://github.com/OSGeo/grass/pull/5665 #5665], [https://github.com/OSGeo/grass/pull/5666 #5666], [https://github.com/OSGeo/grass/pull/5667 #5667], [https://github.com/OSGeo/grass/pull/5668 #5668]

==== Background ====

Standardized basic GRASS GIS dataset is an updated, restructured dataset to be used in manual pages, tutorials, courses, code testing, development and OSGeo Live. Localized versions of the dataset support common instructions, tutorials and teaching materials for different regions in the world.

Datasets for GRASS7 and GRASS8
* Wiki page with examples and list of existing datasets is at [http://grasswiki.osgeo.org/wiki/GRASS_GIS_Standardized_Sample_Datasets GRASS Wiki: GRASS GIS Standardized Sample Datasets].
* Track wiki page with the original discussion for GRASS 7 is at [https://trac.osgeo.org/grass/wiki/SampleDataset GRASS GIS Sample Datasets].
* Download links on GRASS GIS website: [https://grass.osgeo.org/download/data/ GRASS GIS Sample Data]

==== Common rules ====

* Names of map layers must be the same for all standardized datasets. No additions to names such as `_10m` or `_wake_county` are allowed. This also implies that names must be in English, national language is not allowed for national standardized datasets (however, if desired, we can can work on a script which would automatically [http://grass.osgeo.org/grass70/manuals/addons/g.rename.many.html rename multiple maps] in dataset and would also find and replace names in documentation and tutorials).
* To keep the basic data set simple, specialized map layers are moved into separate mapsets, for example, statewide data at lower resolutions or high resolution lidar or UAS based data, data time series, etc.
* Description in tables here should be usable as title of the map. Separate details in description, which should not be part of the title, using commas or parentheses. Titles can differ between standardized datasets and can use national language (unlike names).
