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: github.com/do-me/geospa... @webgpu.bsky.social #gischat

#30DayMapChallenge - 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 www.linkedin.com/feed/update/...

#30DayMapChallenge Day 7: Accessibility Built something special for this year's challenge: GeoParquet Visualizer, a browser-based tool to explore and share your maps easily. Free, open source & super lightweight. App: do-me.github.io/geoparquet-v... GitHub: github.com/do-me/geopar... #gischat

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? ;) ) #gischat

Paper Alert! "Embedding-Based Multilingual Semantic Search for Geo-Textual Data in Urban Studies," is published in @springernature.com I developed an open-source, lightweight method to map phenomena using natural language, like "cherry blossom spots" or "skate parks" with VGI. Demos: geo.rocks/gss

Announcing sff: A fast, on-the-fly SemanticFileFinder written in Rust! 🦀 Scans a dir, finds most semantically relevant files & chunks (model2vec-rs). No vector DBs, no GPU needed. Index ~2500 files w 10k chunks in 250ms. Search your notes 𝚌𝚊𝚛𝚐𝚘 𝚒𝚗𝚜𝚝𝚊𝚕𝚕 𝚜𝚏𝚏 𝚜𝚏𝚏 "𝚠𝚘𝚛𝚔𝚒𝚗𝚐 𝚠𝚒𝚝𝚑 𝚐𝚒𝚝" github.com/do-me/sff

I streamed 86M bluesky posts in my browser from their open jetstreams and naively mapped all mentioned Italian cities. Even though most of them are false positives, it was still a fun app to build! do-me.github.io/bluesky-ital... It's a pity bluesky doesn't offer proper location tagging. #gischat

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

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

New blog post! Spatially filter Foursquare's >100.000.000 rows (10Gb GeoParquet file) in 22 seconds with DuckDB. geo.rocks/post/duckdb_... #gischat #duckdb #geopandas

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. youtu.be/sONjXU4eRss

Bundle geospatial apps with Rust-based tauri. Secure, cross-platform, small sizes and apps open instantly. Check out this minimal app for MacOS I built based on @maplibre.org, @bkgbund.bsky.social's free world vector tiles and @komoot.bsky.social's Photon geocoder. www.youtube.com/watch?v=b0tN...

🌍 #30DayMapChallenge Day 29. Data: Overture – Multilingual Geospatial Semantic Search 🔍 Ever wanted to query places around the world in your local language? E.g. - "예술적인 장소" in Mongolia - "Футбол" in Uganda App: do-me.github.io/overture-pla... More Info: www.linkedin.com/posts/domini... #gischat

Query Foursquare's 100M OS places in a one-liner with DuckDB without downloading! huggingface.co/datasets/do-...
