We have to assume it: most of the potential sponsors for #GDAL are not in Mastodon, but in LinkedIn
@gdal is there as well: https://www.linkedin.com/company/gdalorg

Did you know you can now add an address to OpenStreetMap directly from the CoMaps editor?
Contributing info is easier than ever:
Every address improves navigation and discovery for millions of people worldwide.
Get started today:
1) Tap ‘Add Place to OpenStreetMap’ and select point of address
2) Select the ‘Address’ Category
3) Enter the address and tap 'Save'
Your small edit can make a big difference!

In #foss4ge2025 I was talking about Mercator projection, and what is the difference with "Web-Mercator"
These images (at different zoom levels) show a loxodromic curve (at 45° N) in Web-Mercator (EPSG:3857) - that is a straight line in Mercator (EPSG:3395). In red the loxodromic or rhumline. In blue a straight line connecting the endpoints.
(To reproduce it in #QGIS, deselect "Clip features to canvas extent" for the affected layers as discussed in https://github.com/qgis/QGIS/issues/62654)
Loxodromic curve in Web-Mercator (red) vs straight line connecting the end endpoints (blue). Higher zoom level.

#NOAA Released the "beta" version of the Modernized National Spatial Reference System
It will become the official CRS in the US, probably next year.
Everything is new: geographic system, vertical system, geoid model, state planes,... and to make it funnier, the geographic coordinates move between 1 and 2 meters respect to nad83 🫣
If you want to play with it in PROJ, look at https://github.com/jjimenezshaw/NSRS-2022-PROJ
