I have a #GDAL / #QGIS question for the #GIS‌ commnunity in the Fediverse #askFedi concerning the use of geolocation arrays in raster datsets, i.e. in bands the hold (for example) the latitude and longitude of each cell in the raster.

I'm used to produce datasets in UTM format, for which adding the appropriate georeference metadata is simple. However, in this case I'm producing a raster dataset where the cells are distributed in a “warped” area (think aerial imagery with non-affine transform from data matrix to geo coordinates). I have arrays holding resp. the latitude and longitude of each pixel, and can add it to the dataset, I can specify the GCRS (lat/lon WGS84), but I can't seem to be able to find the metadata to add to the raster so that the goelocation arrays are correctly identified as such.

Online there seems to be only sparse documentation about this, generally implying that this is only supported for specific dataset types in specific formats (usually, the standard format from common satellite data) and the only pages I've found on how to “roll your own” refer to a single old-ish mailing list contribution that recommends the use of a sidecar VRT file. Are there any more modern solutions possible?

Want to go somewhere this weekend, but not sure where?

Try following your shadow...or if you don't want to do that - have a look at where it would have taken you.

I made a thing, and wrote about it:

Finally got a beta build out the door of GeoBlazor 4. Been working on the full rewrite and code generator since August, I believe. Hopefully all that automation and refactoring pay off in the long run with better perf and more features. #dotnet #blazor #gis #arcgis

New blog post: Learning resources for GIS in Python with cloud-native geospatial, PostGIS and more: https://blog.rtwilson.com/learning-resources-for-gis-in-python-with-cloud-native-geospatial-postgis-and-more/

I recently sent a list of learning resources to a MSc student I'm working with, and (with her permission) am sharing in case others find it useful

#Russians strike #Sudzha gas metering station again and accuse #Ukraine of shelling energy sector

The head of the Centre for Countering Disinformation at the National Security and Defence Council, #Andrey_Kovalenko, has already written that it was the #Russians who again attacked the #GIS in a territory that they do not control.

By the way, regarding the violation of the ceasefire agreements: in the last 24 hours alone, the #Russians have struck #Ukrainian energy twice .

Heute lernte ich daß https://geoportal.de/ existiert und ich liebe es.

hello si vous n'avez pas de réunion ou de patates à planter cet après-midi, vous pouvez venir nous écouter @rcarto et moi-même tenter de parler de géomatique et de reproductibilité.

Ce sera à 14h ici : https://univ-grenoble-alpes-fr.zoom.us/j/92393400807?pwd=YtDZwMoxqMVG46RAJ9e3YBBdPlo2Pa.1

La présentation est ouverte à toutes et tous.

Et si le son de nos voix éraillées par les concerts de métal vous perturbe, les diapos sont en ligne là (*jokes non included*) : https://nicolas-roelandt.github.io/2024-reproductibilite-et-geomatique/

Und auch am dritten und letzten Tag der #FOSSGIS2025 haben wir eine Frage an alle, die aus der #GIS-Community in Münster unterwegs sind.

Die Frage des Tages lautet: „ Welche der folgenden Trends wird die Geo-IT-Welt in den nächsten Jahren am stärksten beeinflussen?“

Wir freuen uns über Euren Besuch an unserem Infostand im Foyer und wünschen einen spannenden letzten Tag.

Should we be concerned about the safety of our federal seniors benefits? You know, CPP, OAS, GIC. What about the new Pharmacare and Dental plans? The 2025 election in Canada could make a difference.

make up your mind: is longitude `lon` or `lng`?

I use StoryMaps, which is closing, and I'm going to move to ArcGIS StoryMaps ($). The weird thing in the notification was:
"StoryMaps.com data is stored in the United States. If you migrate your account to ArcGIS Online, your data will continue to be stored in the United States."
In the fine print, if I join ArcGIS, it says:
"...a customer can specify to store their data and services in the EU region..."

WTF is going on?
