Get your ticket soon, and come join an incredible group of people in Utah - you won't regret it. But you likely will regret NOT going, not being there at this inflection point for the CNG movement, and connecting with such an awesome group of people.

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...

The AI tools also really make it much easier to 'drop in' and just spend 20-30 minutes but make some concrete progress.

Do it! The vibe coding for QGIS is amazing these days. My recent learning is to start with plugins.qgis.org/plugins/plug... to start with a good structure. And newborns sleep a lot 😀 - I got through a lot of Breath of the Wild after putting mine (now 6) down. But qgis coding is just as fun...

Matt Hanson and Olaf Veerman kicking off the STAPI sprint 2025

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.

[RFC] Multiple collections in metadata · Issue #88 · stac-utils/stac-geoparquet The spec currently describes how to store a single collection in the metadata: stac-geoparquet/spec/stac-geoparquet-spec.md Lines 72 to 77 in 121f648 ## Including a STAC Collection JSON in a STAC G...

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...

Migrate users to new plugin directory by cholmes · Pull Request #96 · cholmes/qgis_plugin_gpq_downloader This should hopefully close #94 when merged. I'm not totally sure this is the best approach, but is what the AI's (claude 3.7-sonnet) recommended. It replaces the existing directory with a ...

Thank you!

Just download that zip, and in QGIS go to Plugins -> Manage and Install Plugins -> Install from ZIP. Ideally you have v0.6 or earlier of GeoParquet Downloader plugin installed. It should pop up a message & guide you to know what's happening. Please let me know if it works, or what went wrong.

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.

3 lines of terminal commands for using pixi to install qgis

🌶️ 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...

Add a GDAL_RELEASE_NICKNAME define by rouault · Pull Request #11865 · OSGeo/gdal GDAL is an open source MIT licensed translator library for raster and vector geospatial data formats. - Add a GDAL_RELEASE_NICKNAME define by rouault · Pull Request #11865 · OSGeo/gdal

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 🏳️‍⚧️👏🏼🏅

(unless you love SQL and have your lat/long coordinates memorized).

A big thanks to all the new contributors!

I think my favorite (pictured in the gif) is the ability to select multiple
@overturemaps.bsky.social
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.

It's so cool to see the plug-in get better as different people 'scratch their own itch' and add what they think is useful.

New Features of GeoParquet Downloader QGIS Plugin Many new improvements have landed recently, from a variety of contributors, turning this plug-in to a true open source project

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.

Ah, sweet! Yeah, I was remembering you had some nice CLI's, but looking at stac-utils.github.io/stacrs/latest/ and github.com/stac-utils/s... I didn't see mention. You might just throw a link / line in there, that people interested in using it in a CLI can get it at X.
