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

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:

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

We launched #QuickWebViewer, a new plugin for #QGIS to publish your maps online. A solution for low tech requirements and heavy maps suitable for the cheapest servers on the market: https://plugins.qgis.org/plugins/QuickWebViewer/ #webmapping #QWV

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)

Very curious what my fellow open source mappers think of esri's new ai assistant.... https://mediaspace.esri.com/media/t/1_opret32t
