Did 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:

Put in 10 hours of mapping/surveying with #StreetComplete and #OsmAnd. Got a whole lot added. Mapped out every business on the eastern side of Benbrook Boulevard. Also mapped out the sidewalks on the eastern side. Tomorrow I'll try and do the western side. This is a major corridor of Benbrook with a bunch of businesses, so having them all on the map, and updated/fleshed out, should be helpful for folks.

If I wanted to persuade someone who only knows ArcGIS/ESRI products that they should look at QGIS/open-source tools, what particular features should I point to? Aside from being free and open-source - what wow features do they have? What can you do easily that you can't in Arc?

(I don't really know what Arc/ESRI is like these days as I haven't used it for over a decade)

High risk for tornadoes today, particularly in the pink area.

To read NOAA’s forecast discussion click/tap inside any of the large red-outlined areas and then follow the link. The screenshot text is from the discussion for central Alabama.

The map has lots of weather related #GIS layers you can turn on/off/restack. Need help with that? Please read the “Map tips” in upper left corner.

Multiple fast moving wildfires in Oklahoma and Texas.

NOAA has issued a #FireWarning for the shaded areas. Each area is at danger from a fire. For details, open the map, click a shaded area and follow the link.

I have been making #Wildfire #GIS maps for at least 10 years and this is the first time I have seen NOAA issue a “fire warning”.

"Columbine survivor’s death ‘best classified as homicide’: Coroner report "

Is this any different from #GIs dying 30 or more years after war? PTSD is real and it doesn't always present as "Rambo-esque" symptoms.

https://doi.org/10.1016/j.jag.2025.104371 <-- 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 (http://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…

Lasted edited... SIXTEEN YEARS AGO? Well obviously that's getting updated tomorrow.
