Been in the back of my mind of a while; Terra Draw now supports snapping to a given angle, for example here's 90 degrees working with @maplibre.org 📐

I'm not there in person (😭), but if you want a (very rare) Terra Draw sticker for free, there are some available at #foss4g 2026 in Hiroshima

Checking out for holidays after a great few days at #fossge 2026 in Timisora. Met some cool people and even managed to see some of the city when it wasn't 39 degrees 😅

I've been super busy moving out our flat, but a few weeks ago managed to get a bit of a refresh on the terradraw.io website and didn't get a real chance to share 🗺️🖍️

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

I got some marker pins commissioned to celebrate adding marker support to Terra Draw 😎

010

James Milner @jameslmilner.com · 12/10/2025

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

I've been working on an open source library to do routing in JavaScript called Terra Route. This morning I've added functionality for understanding complex graphs, you can get info like the number of nodes, edges, lengths, degrees, connected components etc! github.com/JamesLMilner...

071

James Milner @jameslmilner.com · 14/09/2025

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...

James Milner @jameslmilner.com · 12/08/2025

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.

000

James Milner @jameslmilner.com · 03/08/2025

Scrapped the custom local development environment in favour of @storybook.js.org for Terra Draw. Lots of useful built in functionality and helpers provide cleaner isolated examples of different functionality.

One highlight from the Bosnia trip last week was taking the cable car in Sarajevo up to the top of the surrounding mountain and walking down the abandoned bobsleigh track from the 1984 winter Olympics

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

Amazing last day in Mostar presenting about Terra Draw for FOSS4G EU. Thanks to everyone who came along or caught the live stream #foss4geu

I've added a way to understand graphs a bit better in Terra Route (a GeoJSON path finding library). You can use it to see if graphs are disjointed, the number of nodes, edges, lengths etc. You can check it out here: github.com/jameslmilner...

A minor milestone for a lot of projects, but Terra Draw hit 10k downloads a week on npm this week 🎉

060

James Milner @jameslmilner.com · 09/06/2025

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

James Milner @jameslmilner.com · 08/06/2025

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 ✏️📐🌏

James Milner @jameslmilner.com · 01/06/2025

catching up with @bertspaan.nl who gave me all these fun @latest.allmaps.org stickers. New version of Allmaps Editor powered by Terra Draw coming soon 😎

Terra Draw is now used by the UNDP GeoHub - thanks to Jin Igarashi for his work making that happen!

020

James Milner @jameslmilner.com · 13/04/2025

Working on a new version of Terra Route - if all works out it'll be about 45x faster than ngraph.graph and about 22x faster than GeoJSON Path Finder (both great libs).

It could work nicely on mobile apps for places like uni campuses, national parks, theme parks etc where the networks are quick to download and have a small memory footprint

James Milner @jameslmilner.com · 02/04/2025

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.

James Milner @jameslmilner.com · 11/03/2025

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