Experimenting with a little undo/redo ↩️

After a long time, I finally figured out how to support adding markers universally in Terra Draw. Now there's a marker mode that works for @maplibre.org , @openlayers.org, Leaflet etc. It uses their native marker support to allow you to add icons to the map, like you would add a point

Made some performance improvements to Terra Route, a JavaScript shortest path library. Here's a video at 4x CPU slowdown, comparing the next fastest library (green route) against my latest changes (purple route). Here's the link: github.com/jameslmilner...

I've taken this a step further today - we can now test to ensure all examples load without error, essentially creating a series of smoke tests for all mapping libraries. This adds a little bit of extra confidence in changes being made to the project going forward.

The request to draw freehand lines in Terra Draw keeps popping up so I've been experimenting with it a little this evening and it's actually a lot of fun! Little demo on a @maplibre.org map #foss4g #gischat

Terra Route latest update goes from 1.5x faster than the alternative library to 2.25x faster for route finding! This works well with Terra Draw in a custom draw mode, where you draw out multi-stop routes in real time

Been working a bit more on snapping polygons today in Terra Draw, now when you have a polygon selected you'll be able to snap it's vertexes to other polygons ✏️📐🌏

I've been working on improving a route snapping mode implementation for Terra Draw, and ended up creating a whole new library for efficient clientside routing on GeoJSON. It's about 35-68% faster than prior art depending on configurations.

Terra Draw supports custom snapping implementations for the polygon mode - I did a little proof of concept for snapping to right angles 📐✏️
