@irina@critter.cafeif you're the kind of Australian who's interested in having a physical street atlas for the current year - be warned, UBD Gregory's is shutting down.
Rumor [youtu.be] is Sydney, Brisbane, Adelaide, and Perth will get one more edition in August[?], but for everywhere else (seemingly including Melbourne and Tasmania), what's on shelves is probably the final edition.
now please excuse me while i tag spam

@underdarkGIS@fosstodon.orgDid you know that you can package a complete #QGIS 
project (incl. all your layers and data) in a single #Geopackage file, e.g. to move it to another system?
Practical examples, on the new hub:

HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."

Making Maps Smarter with Open Data 
The Overture Maps Foundation is transforming how map data is shared & used. With Amy Rose as its first CTO, efforts continue to make mapping more open, accurate & connected.
Learn how open data is shaping the future of maps: 
Read the blog: https://overturemaps.org/blog/2025/making-open-data-part-of-a-national-data-infrastructure/
Are you using Leaflet, but you want to incorporate our vector styles?
Learn how with the help of MapLibre GL JS and our tutorial.

I love looking through https://native-land.ca. I learn something new every time I go, usually by just clicking on one of the random articles on the side. It's pretty clear that it's a small team behind it, and I wish they had more resources to be able to put more indigenous languages on the map (literally!).
If you have some time on your hands and a passion for language, I'd highly suggest checking out their Volunteer page: https://native-land.ca/how-to-contribute/volunteer It's a lovely way to contribute to/learn about global Indigenous sovereignty and lift up marginalized voices. Each language is a worldview; we can learn so much if only we look for it!
Also this is Ariel; I'd post this on my profile but wandering.shop has a very small character allowance and I am way too long-winded for it, I have found :P

Here's your chance to learn the fundamentals of digital mapmaking!
This six-week course is a practical how-to course that demystifies digital tools and translates mapmakers’ jargon into easily understood terms.
We'll be using open-source free software, and no experience is necessary.

Speaking of apps and tools for mapping and navigation, https://www.accessmap.app/ uses OSM data and accounts for curbs, crossings, and slopes to help people achieve car-free mobility.
StreetComplete helps you contribute on the run.
Go Mapp!! works on iOS.
If you know other cool mapping tools, please share!
Google Maps just dropped a new feature using AI to add crossings. It's an imperfect step in the right direction.
The #OpenStreetMap community knows mapping these features with AI is a challenge. We do a fantastic job with this working by hand! If you prefer the image on the right to the image on the left, consider helping us!

This is an #introduction post to list some of my interests and inclinations. Here goes! I value #kindness and things that build #community. I fight for #privacy. I am fond of #dogs, #books, #information, #mapping, #GPS, #fitness things, #corvids, and lazy #genealogy. I use and promote #OpenSource software. I like the outdoors; you may find me #gardening, #cycling, and exploring. I live in #Canada. I will eat the dark chocolate before you find it.
