Un chercheur français du CNRS refoulé des Etats-Unis pour avoir exprimé "une opinion personnelle sur la politique menée par Trump". Ce chercheur dans le domaine spatial a subi un contrôle aléatoire à son arrivée à l'aéroport, au cours duquel son ordinateur et son téléphone personnel ont été fouillés. Le FBI a ouvert une enquête contre lui, depuis abandonnée. Les Etats-Unis ne sont plus une démocratie lemonde.fr/international/artic

Multiple Intelligences

Dr. Howard Gardner’s theory of multiple intelligences seems really fascinating:

#Linguistic intelligence (“word smart”)

#Logical-mathematical intelligence (“number/reasoning smart”)

#Spatial intelligence (“picture smart”)

Bodily-Kinesthetic intelligence (“body smart”)

#Musical intelligence (“music smart”)

Interpersonal intelligence (“people smart”)

Intrapersonal intelligence (“self smart”)

Naturalist intelligence (“nature smart”)

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…

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!

If you are interested in maps and city views and especially in the 'boundaries' between city and countryside, please have a look at this video: youtube.com/watch?v=4SBmTdwOnQ
I call this #boundary a 'spatial differentiation'. Please share your thoughts.
The video could also be a useful teaching tool for BA seminars in in #History , esp. #urban and #spatial history.
... includes a reference to my work on Delagrive: shs.hal.science/halshs-0445346

Hello Fediverse!

I'm currently writing a master thesis where I will need to get some data on weather of different (mostly) European cities with some GPS coordinates for the last 5 years.

As this is a student project, I do not have much money to pay expensive API access to historical weather data.

Does anyone have a recommendation?
Thank you and try to be nice to yourself today :)

Hi #sciencemastadon, just migrated to social.edu.nl. A re-introduction: I'm a researcher working at Wageningen University and Research (#wur), studying the #ecology of #marinemammals (mostly #seals) in the Netherlands or #arctic, analysing #spatial distribution and #habitat selection based on #wildlife #tracking or #drone/ #uav/ #satellite data using #rstats

Also interested in human #behavioural ecology and alternative economic systems like #degrowth/ #postgrowth
