With today's Zarr Python release, switch to the new obstore-based backend for **3x faster** reading from S3, Google Cloud Storage, and Azure than the default fsspec backend. zarr.readthedocs.io/en/stable/us... developmentseed.org/obstore/late...

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...

Day 1 in the books from the Satellite Tasking API #STAPI sprint 2025 in Lisbon! We've got four sprint groups: - spec - frontend - software - vendor implementations Watch github.com/stapi-spec/ for all the changes! Organized by @element84.com, hosted by @developmentseed.org, and sponsored by #aws

I'll be at the Cloud Native Geospatial Conference (2025-ut.cloudnativegeo.org), talking about using GPUs for geospatial workloads. Let me know if you have any experience or interest in this and would like to chat.

As we push adoption of stac-geoparquet, we've found some cases where we might want to store multiple collections in the metadata. I made a light RFC here, if you're intersted: github.com/stac-utils/s... #stac

damn this is a good article from @pketh.org pketh.org/the-human-to...

Is anyone up to test my geoparquet downloader qgis plugin? We want to change the directory in the latest release, which means migrating users from the old plugin to the 'new' one. If you could try out github.com/user-attachm... and let me know how it works I'd appreciate it.

🌶️ pixi.sh is the easiest and fastest way to install #QGIS on Ubuntu (maybe Mac too) right now if you need access to GeoParquet and DuckDb formats and python libraries for plugins 🧵 #gischat

We've published 118,678,424 open-data field boundaries so far. The boundaries have been collected from different open data portals, in different formats, and are now published in a single format. If you're creating farmer software solutions and need field boundaries, use them to your advantage...

All open source is political. Even Rouault – archetypal GIS "random person maintaining the code that supports all modern digital infrastucture" – commited to GDAL github.com/OSGeo/gdal/p... - will now print "Trans rights are human rights" with `--version`. #gischat 🏳️‍⚧️👏🏼🏅

Just published a post on new features in the GeoParquet Downloader QGIS Plug-in I've been working on, see cholmes.medium.com/new-features... The most exciting thing to me is that a majority of the new enhancements have come from outside contributors.

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.

It turns out the demise of the geo-blog has been greatly exaggerated. Blog-like content has been hiding in plain sight and it may be needed now more than ever. blog.geomusings.com/2025/02/16/l...

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.

This is a great package, I need to use it more. Love the stac-geoparquet support, especially leveraging DuckDB.

We're seeking funding to take @source.coop to the next level.

I just published a blog post sharing some videos on how to make a QGIS plugin with AI coding tools: cholmes.medium.com/learn-how-to... I've been having great fun with it, so wanted to help demystify the process for anyone curious, and hopefully inspire more people to add cool stuff to QGIS!

Helping start Fiboa (github.com/fiboa) and Fields of The Worlds (fieldsofthe.world) as part of TGE's first Innovation Bridge is easily the thing I'm most proud of contributing to last year. Read this great blog post summarizing what happened: tgengine.org/innovation-b...

You, yes you, can help the Cloud Native Geospatial Movement! Have you benefitted from Cloud-Optimized GeoTIFF’s? SpatioTemporal Asset Catalogs? Zarr, COPC or GeoParquet? And the ecosystem around them? Learn how to give back in my post: cholmes.medium.com/you-yes-you-...

New release of obstore: the simplest, highest-throughput Python interface to S3, GCS & Azure Storage! - Pickle support, to unblock usage in Dask and Zarr - Easier one-line store creation - Open remote objects as file-like readers or writers - Improved docs developmentseed.org/obstore/late...

I finally found the time to write up my experience using AI-coding tools to create the QGIS plugin I made a couple months ago to make it easy to download Overture Maps Foundation, Source Cooperative and other GeoParquet data. Read it at: cholmes.medium.com/coding-qgis-...

We are excited to introduce Kepler.gl 3.1, including enterprise-grade features like an embedded @duckdb.org Engine, an LLM Assistant for visual analysis with support for OpenAI, DeepSeek AI and local Ollama models, and PM Tiles support: location.foursquare.com/resources/bl...

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?

Does anyone have good experience using the US National Hydrography Dataset (NHD) dataset? I'm contemplating translating it into GeoParquet to make it easier to download portions of it. But it's got a ton of tables in the GeoPackage - do people use all of those? Or is there a key subset?

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...

This is 80% for my future self, but others may find it interesting: savasalturk.medium.com/taking-geosp... This 'panel' things sounds cool, I've wanted to try a project with MapLibre for a long time, and I of course love DuckDB.

Just wrote overview of the QGIS plug-in I started a couple months ago to make it easier to download data from Overture, Source Coop and anywhere with GeoParquet data. Read it at: cholmes.medium.com/a-deep-dive-... And I aim to follow it soon with a deep dive into using AI coding tools to make it.

Agreed, it’s great.

📣 Just released pystac v1.12.0, which includes STAC v1.1 and support for v2 of the projection extension: github.com/stac-utils/p... Big shout out to all the contributors, especially @jsignell.github.io who got this one over the line. Part of the #python #stac ecosystem

📢 STAC Browser v3.3.0 has been released! Some of the improvements: - STAC v1.1.0 support - Updated versions of STAC extensions - New languages - Better authentication system, supporting OpenID Connect, HTTP Basic and API keys - Improved social sharing More details at github.com/radiantearth...

I just put up a new repo to share some tools for working with GeoParquet. * Check best practices for bbox column, row groups, etc. * Apply DuckDB's Hilbert curve (and keep projection) * Add a column of iso country codes, and then partition on it. Read more at: cholmes.medium.com/sharing-some...

New obstore v0.3 for easy access to S3, GCS, and Azure Storage! - Easy **streaming** downloads, uploads, and copies across object stores via async iterators - Streaming list, with no pagination - Easier configuration with improved type hints - Fsspec integration developmentseed.org/obstore/late...

@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: cholmes.medium.com/using-duckdb...

Quick site visit at Snowbird to get a sense for our venue for @cloudnativegeo.org conference at the end of April. This place is unbelievable and will be a wonderful experience for our community. The rates we got for rooms here are also unbelievable – get tickets while you can! Agenda coming soon!

Spatial indexes, and RTrees specifically, are at the core of geospatial software. But ever wondered how an RTree is actually implemented? In this post we’ll dive into the implementation of Flatbush, an elegant, blazing-fast, memory-efficient RTree. kylebarron.dev/literate-fla...

I think #STAC API search parameters, with extensions, can be a "lingua franca" for geospatial search, regardless of whether the underlying data store is STAC. Here's the search parameters I'm talking about: www.gadom.ski/stacrs/lates... Reasoning in 🧵

If you need a quick, but fairly deep introduction to GeoParquet -- I recommend you to listen to an episode of the MapScaping podcast with Kyle Barron. https://buff.ly/3D23bn7 #gischat #rspatial #geopython

Releasing geo-index 0.2: Fast, memory-efficient, zero-copy spatial indexes (RTree & KDTree) for Python & Rust. - Range, nearest-neighbor queries - Persist indexes as bytes, reuse them later - Supports float32 for 2x less memory - Enables GeoParquet spatial partitioning github.com/kylebarron/g...

can't do it all, everywhere. i'm done maintaining stactools, if you'd like to step up and help, please open an issue on that repo! thanks! 🙇 github.com/radiantearth...

This spurred an update to the QGIS plug-in for the latest Overture release, with the bathymetry layer added as an option. Hopefully it should be a bit easier for new users to install, with improvements to attempt to automatically download DuckDB.
