that's right #gischat is one of those niches that needs to know

R Interface to DuckDB Database with Spatial Extension Provides an interface between R and the DuckDB (see ) database with spatial extensions. It supports reading, writing, and performing some geometric operations.

No more sf::st_as_text() or st_geomfromtext() to move geospatial data between {sf} and duckdb spatial 😃 https://cidree.github.io/duckspatial/ #gisChat #Rstats #DuckDB

An overhead document camera films a pile of papers and the nearby computer shows the image.

I'm prepping for tomorrow's FOSS4GNA version of Hand Drawn Maps, making sure the camera works with this computer. Join me tomorrow for some map fun!

A pika sits on a mossy rock.

Tighter crop of the same pika, focusing on its head.

An even tighter crop, focusing more on the pika's eye.

An extremely tight crop of the pika's eye, emphasizing their reflection of an early morning mountain scene.

"Pat, why do you carry that ridiculous 600mm lens on long hikes?"

Buddy, I can see mountains reflected in the eyes of a trailside pika.

I really don’t feel like posting anything except hummingbirds. Sorrynotsorry.

"Optimizing Geospatial Data for the Cloud" "A zine exploring common formats" "Development Seed" "Gus Becker Kiri Carini" A floating robot with one hand on a keyboard to a computer that has a glove on the screen. The other hand is giving a thumbs up.

A raccoon character asking about smoke data, and a floating robot describes how vector format may be more efficient than raster in some cases.

Zines are a great tool for science communication. Earlier this year, I put one together with @kiricarini.com of @developmentseed.org.

The zine provides a visually interesting jumping off point for folks learning cloud-native geospatial data!

A black line drawing of an owl is on the left. On the right is text that says hootenanny FOSS4G North America 2025 Reston, VA. The hoot part of hootenanny is emphasized with larger text.

I submitted this design to the @foss4gna.bsky.social design contest. (We're having a hootenanny instead of the traditional gala this year because we're not really gala people.) Don't you want this as a sticker?

You can submit a design too! www.foss4gna.org/contest

📢 We’re hiring and looking for a Geospatial & AI Engineer. This is a remote-first position; however, you must reside in an ESA member country to be eligible to apply.

This role focuses on backend engineering & cloud-native pipelines. AI/LLM skills are a plus, but not a must.

oh I can help you, I just learned it recently github.com/conda-forge/...

ps the bot notifies the listed maintainer in the recipe repo

conda-forge has a bot, but I think it only rebuilds on new releases. In general the R world in conda-forge is generally behind and only as good as the community contribs. The bot test build will fail if deps change.

Its used both ways, log what you saw, or get help with ID. I suspect reporting is more common as Seek also from iNaturalist is more often for ID.
