I've updated my Go native port of Uber h3 https://github.com/akhenakh/goh3 to h3 to the v4.2.1 release.
Being native makes it useful in situation where CGO is not an option, it is used, for example in my geo tools for Bento https://github.com/akhenakh/geo-bento #h3 #golang #gis

The largest competitor to commercial #GIS is open source software and tools – #FOSSGIS infrastructure is now at a level where municipalities and companies shift away from commercial solutions. Would anyone happen to have any material (case studies etc.) on this topic to prove this point?

Afgelopen vrijdag verzorgden we vanuit #QGISNL 2 workshops tijdens de Open GIS 3D Studiedag voor gemeenten, georganiseerd door @gemeenteamsterdam, #VNG Realisatie & @osgeonl: @hansakwast over puntenwolken en #3D visualisatie in #QGIS & @terglobo over 3D-data exporteren van QGIS naar #Blender3D. Het was een heel nuttige dag om kennis uit te wisselen over #opensource 3D-technologie! #OSGeoNL #GIS

Das war die #FOSSGIS2025 in Münster.

Wir waren wieder als Platinsponsor mit unserem Team vor Ort und freuen uns, an so einer erfolgreiche Veranstaltung teilgenommen zu haben. Wir sind bereichert von dem regen Austausch mit Expertinnen und Experten der GIS-Szene, aufschlussreichen Vortragsthemen und der Diskussion spannender neuer Erkenntnisse!

Alle Vorträge wurden aufgezeichnet und sind auch online verfügbar

Ich hab da mal was vorbereitet ...

... und zwar ein Glossar.

Nach der 5ten oder 6ten Folge aus der Staffel #fossgis2025 bin ich nämlich aus dem AküFi-Cyber-Zauber nicht mehr rausgekommen. HDV, ALS, GRASS, GML, INSPIRE. JOSM, LiDAR.... Da rauchte mir die Birne... Nicht lange überlegt habe ich mal ein Glossar angefangen. Auch gerne zum mitmachen. Einfach kurz bscheid geben. Hedgedoc Dokument ist offen:

“The rgrass package allows us to interact with GRASS tools (and data) serving as an interface between GRASS and R. The rgrass package source code can be found at: https://github.com/OSGeo/rgrass. In this fast track tutorial, [they will teach you] how to use GRASS from R…”

OpenStreetMap allow you to visually examine it's database before using the API for a specific request via {osmdata} etc. Search on openstreetmap and then the area you want. Use the cursor with the question mark to query the features in the map. #rspatial #gis

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.
