Anita Graser 🇪🇺🇺🇦🇬🇪

This has been way too long in the making and it's finally out:

"Spatiotemporal Model Cards", basically a cheat sheet for documenting #GeoAI models so that you'll thank your past self when you circle back to your docs in the future

📋 Markdown template ... https://github.com/anitagraser/model-card-template
📝 #OpenAccess paper with all the details ... https://dl.acm.org/doi/abs/10.1145/3809183

Still planning to put the essential explanations into the template to make it easier to use without consulting the paper 👩‍💻

#SpatialDataScience

Do I have any followers here who used scikit-mobility's human mobility metrics?

Since #skmob isn't maintained anymore, we're considering porting the essential functionality to @movingpandas and would love to have more feedback, especially if it's first-hand experience with the functionality:

https://github.com/movingpandas/movingpandas/issues/496

#GIScience #MobilityDataScience #MovementDataAnalytics

@paleolimbot definitely ended up in the wrong dimension

#punintended #sorry

Will we finally get nice html representations of @movingpandas Trajectories and TrajectoryCollections?

Inspired by #pydata #xarray 🤩

WIP 👩‍💻 : https://github.com/movingpandas/movingpandas/issues/293

Any feedback / ideas welcome!

Getting a s***-ton of CSV files as input for spatial analysis can be a pain.

Yes, you can write a quick Python loop in the #QGIS console to load them but it's not a great workflow, imho.

The DuckDB read_csv function has been very convenient for this kind of ETL workflow:

The quest for a fair TimeGPT benchmark

At the end of yesterday's #TimeGPT for mobility post, we concluded that TimeGPT's trainingset probably included a copy of the popular BikeNYC timeseries dataset and that, therefore, we were not looking at a fair comparison ...
