Apple built the most powerful browser-based open source GIS without even intending it. I forked their Embedding-Atlas, added
@maplibre.org
support and now you have a WebGPU-ready GIS, table, graph and SQL support for 100M datasets! Have a look:

- Day 17: A new tool - A new GIS! The most efficient in-browser GIS in 2025 is Embedding Atlas from Apple and built with
@duckdb.org
. Originally designed to visualize embeddings it makes for a great GIS! Loading 21M addresses: zoom & pan smoothly

You can use three.js as GIS to render contour lines from a Geotiff with customizable labels! Work in progress. (P.S. can you tell where this might be? ;) )

It's a pity bluesky doesn't offer proper location tagging.

Leaflet 0.8-dev from 10 years ago with a high performance
@protomaps.com
basemap canvas renderer from 2025? Yes it works ๐ So if you have legacy systems running where you don't have the resources to upgrade you can still replace costly raster tile APIs.

Geospatial graphs have something inherently artsy! Working on large POI DBs at the moment but I'm just too fascinated by these patterns...

After a couple of hours of fixing xcode-related errors I finally managed to bundle my basemap app for iOS. Using
@maplibre.org
,
@bkgbund.bsky.social
bund.bsky.social
free world vector tiles and
@komoot.bsky.social
Photon geocoder. Next is Android & a more advanced feature set.
