Variograms

Description

An article on variogram-based spatial analysis.

The content of the tutorial is there; however, I am still testing deployment (qmd -> hugo, see below).

Task list

• My tutorial or article is placed in a subfolder of tutorials/content
• The filename of my tutorial or article is index.md. In case of an Rmarkdown tutorial I have knitted my index.Rmd to index.md (both files are pushed to the repo).
• I have included tags in the YAML header (see the tags listed in the tutorials website side bar for tags that have been used before)
• I have added categories to the YAML header and my category tags are from the list of category tags

Note on rmd: I went ahead to attempt building this tutorial on quarto qmd. I rendered it as a hugo-md, because md-document did not have the correct output. Because this is still testing, I did not include the png images yet to save git overhead. I tested everything locally and finally added the figures.

Previewing the pull request

Thanks to GitHub Actions, an artifact (=zip file) of the rendered website is automatically created for each pull request.
This provides a way to preview how these updates will look on the website, useful to contributors and reviewers.

Instructions to preview the updated website

1. On the PR page, you can find a "details" link under "checks - On PR, build the site and ...". Go there, click on the top link in the left sidebar ("Summary"), and download the generated artifact at the bottom of the page.
2. Decompress it and make sure the target directory is called 'tutorials' (you may need to rename it)
3. From the parent directory (just above the tutorials folder you created/renamed), run python -m http.server 8887, or launch the Google Chrome Web Server app and point it at the parent directory.
4. Point your browser to http://localhost:8887/tutorials.
5. Review the updated website. As a contributor, you can push extra commits to update the PR. As a reviewer, you can accept/refuse/comment the PR.

Note: for step 3, you can use any other simple HTTP server to serve the current directory if you don't have a Python 3 environment or Google Chrome available.

I have tested the asset locally, it should compile everything well for this particular tutorial. I hope nothing else broke...
There are some notable new capabilities with Hugo:

• callout boxes (rudimentary, but working; more colors would be nice)
• equations (via katex)

Working via manual fiddling:

• section anchors
• figure captions

Thank you for you feedback!

Please wait with the review @florisvdh @ThierryO
I have found the reason why my Matérn regressions did not work well, which spawns some interesting further ideas.
I will adjust and resubmit.
Thank you, and sorry for the inconvenience in case you already started!

[falkmielke]

My additions are in.
Thank you in advance for the review!

Some more implementation tricks have emerged from the watina/waterlevel analysis.
Thank you again for reviewing, if you find the time, @florisvdh @ThierryO !
