We're supporting the @openstreetmap.bsky.social community by providing a new map layer for their website. Thanks to #VectorTiles technology, you can now read map labels in your own language, no matter what part of the world you are looking at! www.openstreetmap.org#map=9/46.780... #WebMapping

It’s nearly lunchtime at FOSS4G Europe, make sure you drop by our stand and say hello. We have experts in cartography, spatial data, web mapping, geocoding, JavaScript, and more! #FOSS4G #FOSS4GEurope #foss4ge2025 #WebMapping #SpatialData

New blog post by Tim Appelhans: State of the (open source) web map – Part I: The base(map)

A thoughtful dive into the open source web mapping tools. Recommended.

Another little #webmapping project with #leaflet (mostly) finished and blogged

https://tlohde.com/blog/2025/04/bagging/

I'm not sure if hiking motivates me to poke around with #maps and data more than poking around with maps and data motivates me to go hiking.

Image taken a week ago at our camp in between Chno Dearg and Stob Coire Sgriodain.

Wrote myself a how-to (or rather a "how did I?") for adding #leaflet maps to my #11ty site.

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:

https://tlohde.com/blog/2025/03/shadow-chasing/

Seeking recommendations for a #WebMapping tutorial / course?

Slightly at sea on where to start.

- My current JS skill level is _extreme novice_.
- I don't have access to ArcGIS.
- Comfortable with #QGIS [*] and the #python #geospatial ecosystem (#geopandas #xarray #rasterio and plotting with #matplotlib)

Suggestions welcome. TIA.

* I have looked at the qgis2web plugin, but having some issues associated with my aged laptop (2012 mbp running Ubuntu) and a 'Wayland session'.

Liebe #GEO / #GIS Menschen, ich suche einen klassischen Kataster-Nordpfeil so wie im Bild als SVG-Datei. Hat jemand so etwas in petto?
Vielen Dank!

Anyone has tips how to conveniently show large dataset linked to H3 grid (level 10, over part of Europe) on a MapLibre map? I've found https://github.com/INSPIDE/h3j-h3t but getting h3t seems quite cumbersome and the only other solution I can think of is to use tippecanoe and turn it into PMTiles. But that sorts of defies the benefits of H3. I thought I could somehow simply ship just the H3 IDs but can't force myself to write a code to generate h3t from scratch... #webmapping #maplibre #h3

Perhaps I am the only one who ever needs to quickly look up the z/x/y or quadkey for a map tile, but I made this thing a while ago to do just that. Ehm, enjoy, I guess? https://mvexel.github.io/whatthequad/ #gis #maps #webmapping

We've introduced a lot of exciting updates with Felt 3.0! Explore our revamped user interface and discover all the new features. https://youtu.be/99roNtqD4GQ

Very interesting new QGIS plugin, to sit alongside #qgis2web. QuickWebViewer exports QGIS projects to MapLibre: https://gitlab.com/300000-kms/QuickWebViewer #OneToWatch #webmapping

#MapTiler Customize tool now has a completely new experience for #map icons.

Recolor on the fly or pick from over 200 new symbols.

Try it out here: https://buff.ly/3IwA5vH (with free MapTiler account)

Hi @kimaidou, do you know, does #Lizmap support identify results / popups for raster layers?

I checked out the demos (https://demo.lizmap.com/lizmap/) but couldn't find any with raster example to answer my question.

Thanks.

Hi @felt, I'm trying out your custom basemap option and have run into issues when trying to use the Austrian basemap.at service. I copied the URL over from #QGIS where it works as expected:

http://mapsneu.wien.gv.at/basemap/geolandbasemap/normal/google3857/{z}/{y}/{x}.png

Do you have any pointers for me?
