Last week, we hosted "Advances in Spatial Machine Learning 2025", a two-day workshop tackling open challenges in the field.

From validation to uncertainty analysis, we explored key topics with top researchers.

Now, we're working on synthesizing outcomes—stay tuned!

I think I already asked something similar a few weeks back, but isn't there a public site where I can fetch #Copernicus GLO-30 #DEM files with a simple http client anymore? I used to use `wget` for this, then it was AWS CLI, and now it seems I have to set it up with a user/pass/key/secret_key?

I remember cloning the whole mapzen repo when it was on peril of disappearing, should I have done the same with data that's supposed to be public? Has anyone done that already?

So, who knows what's up in State College PA? I'll be visiting soon to speak at a #GIS conference, and would kinda like to see more than the conference center!

"GeoTrellis is a Scala library and framework that provides APIs for reading, writing and operating on geospatial raster and vector data. GeoTrellis also provides helpers for these same operations in Spark and for performing MapAlgebra operations on rasters. "

Done mapping all 40 #barangays of Luna, La Union, #Philippines in #OpenStreetMap, creating their #Wikidata items, and linking the two with each other.

A huge thanks to JR Dizon of the Luna Municipal Planning and Development Office for the boundary data.

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 ...

Want to go somewhere this weekend, but not sure where?

Try following your shadow...or if you don't want to do that - have a look at where it would have taken you.

I made a thing, and wrote about it:

#TimeGPT for #mobility: Can foundation models outperform classic machine learning models for flow predictions?

tldr; Maybe. Preliminary results certainly are impressive.

NEW Maxar Open Data pre-event imagery for the Myanmar earthquake now available:

#OpenStreetMap #GISChat question: Our county has very high quality (3-inch resolution) aerial imagery: https://lio.danecounty.gov/services/flydane The main way they make it available is through an #ArcGIS web portal: https://dcimapapps.countyofdane.com/dcmapviewer/?org=countyofdane but you can also download GeoTIFFs.

This would be an amazing data source for OpenStreetMap if the licensing allowed for it. Has anyone had success in getting permission to use similar datasets for OSM from a gov agency? Any email templates to ask for it?

A little drone operation from last week - and a shameless #fediSelfPromotion.

I do data collection in places that are not vehicle accessible really well.

This is a small project for ecological assessment over time - 'right data for the job and client', using a fully backpack-able system.

I'm happy to discuss future projects - especially if your blocker is "hmm we can't get there"

Hey #gischat - this looks like an interesting opportunity. Want to team up and take it on? (I'd sit in the project management space, my code-fu is strictly research/exploratory grade ;) )

I am toying with the idea to build a (physical) globe myself. Preferably using #QGIS and maybe Inkscape for final touches (or other OS tools).

I would like to design the globe as far as possible in QGIS and then use an appropriate projection to output the lobes. Then glue to a sphere using wallpaper glue etc. - I imagine it difficult to get the labels right.

Surprisingly, I can find few resources on how to approach such a project.

Any pointers or own experience?
