Another #fosdem advice: you won't find power outlets at the campus. Arrange so that your devices last through the day without getting plugged in.

Excited to share that maplibre-gl-lidar v0.6.0 is now available!
This release adds support for the Entwine Point Tile (EPT) format (entwine.io/en/latest/en...), making it possible to stream and visualize billions of LiDAR points directly in the browser with ease and performance.

I've been working a little on Terra Route today and the accompanying drawing mode for Terra Draw. You can use these together to do browser based map routing. I made some performance improvements that I think that even for decent sized areas the route snapping feels instant for the user

Interop is brilliant. Aligning the efforts of all browsers around crucial focus areas every year is doing wonders for interoperability, and its effect is compounding.
Switch to the “experimental” tab (which is not about experimenting, but about what is definitely coming soon) and you can see that every browser reached at least 98. Once all this engineering work ships in browsers, the overall interoperability for these 19 Focus Areas is 96%!
