Working towards a Cloud-Native Geospatial future, through involvement in GeoParquet, Planet Labs, Taylor Geospatial Engine, Fiboa, STAC & Source Cooperative.
The first Cloud-Native Geospatial Conference is happening in three weeks! I'll be giving the opening keynote, and I'm working to make it one of my best talks ever. The agenda (2025-ut.cloudnativegeo.org#agenda) is incredible, but there's also going to be lots of space between the talks...

I think my favorite (pictured in the gif) is the ability to select multiple

layers and then have the plugin download them all at once. I'm pretty confident it's now the easiest way to get a bunch of Overture data for your area of interest.

I'm incredibly pumped that we'll be launching 'phase 2' of the TGE initiative that lead to Fields of The World (fieldsofthe.world) and fiboa (github.com/fiboa). And I'd like to invite you to join us!

See tgengine.org/tge-innovati... for the full post, and read on for some more information.

I'm updating the GeoParquet website with the latest tools and data. See new version at e2958fef.geoparquet-github-io.pages.dev and diff at github.com/geoparquet/g.... What am I missing? I added duckdb, kepler gl, felt, atlas, big query, overture. @kylebarron.dev - do you have a rust library now?

Awesome, thanks for responding. Stream order would just be an attribute of the flowline? Yeah, makes sense to me to include that, and could filter it out when streaming.

I was more wondering about all the tables, see attached. Like the ones with no geometry? And all all the geometry ones?

Taylor Geospatial Engine just published a blog post I wrote about a demo we put together to show the potential of using a custom LLM interface to explore interoperable field boundary data. Check it out at tgengine.org/exploring-fi...

@maxxen.bsky.social
taught me how to use DuckDB's ST_Hilbert function properly, so I put together a post on how to use it, and to get GeoParquet output. Featuring Planet's basemaps and a month of PlanetScope footprints. Read at:

My Overture/Source Coop/Cloud downloader QGIS plug-in is live! It lets you download a GeoParquet or GeoPackage for just your view port from hosted GeoParquet files.

Check it out at plugins.qgis.org/plugins/qgis... and install it by searching for 'GeoParquet Downloader' in the QGIS plugin manager.

Yeah, and they go back 7+ years. Near daily imagery lets you get pretty close to cloudless imagery over quarterly or monthly cadences.

Got this working with my (still unannounced except for here) QGIS plugin. Not as fast as Overture since the files themselves aren't spatially partitioned (yet), but a big improvement from the previous release, as it's GeoParquet and works! Cool to see it on Hugging Face.

Anybody up to test out my new QGIS plugin and confirm it works? I'm waiting for approval on plugins.qgis.org/plugins/qgis... but you can download and add as a zip from github.com/cholmes/qgis.... Enables download of the viewport of Overture, source.coop or any GeoParquet URL.
