Summer 24 somewhere in Sweden.
After a delicious dinner, we went for a digestive walk with the midnightsun and making some survey. Of course I used the Osmand app with Quick Action function, Streetcomplete and took pictures with Mapcomplete.

Glacial Lake Mapping Using Remote Sensing Geo-Foundation Model
--
doi.org/10.1016/j.jag.2025.104 <-- shared paper
--
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..."

The Concept Of Indigenous GIS
--
Reading a paper (alturl.com/8wte5), they used the specific term ‘Indigenous GIS’ – and I found this intriguing!
As I read it, spatial data collection and analysis was done with a focus on how a tribe or social group might ‘see’ the data, including spatiotemporal....
I look forward to finding out more about what others are working on! – so PLEASE feel free to share any examples that you might have…

I do use online/offline mapping systems all the time on my GPS, phone and other tech related gadgets. But, I have to say, there is nothing quite like getting a paper map arriving in the post.

I'm like a kid with a new toy and excited to see what lies within. I can dream of adventures to come better with a paper map than with online mapping systems.

Now to seriously plan our 7-10 day backpacking trip in the Pyrenees

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!

First time? Check out: openstreetmap.us/get-involved/

The image is a comparison of Google's recently released AI crosswalk mapping technique compared with mapping done by volunteers.

Need spatial data?

The list of ArcGIS server addresses that I curate now has over 4,000 addresses for ArcGIS servers at all levels of USA government, from federal to local.

Last fall, Jonathan at geoseer.net/ (spatial data search tool) sent me a massive list of ArcGIS server addresses that have been detected by their scanning methods. I finally had a chance to process that information and added *many* ArcGIS server addresses to the list I curate. Thanks Jonathan!
