I built GeoUtil.com to provide a free, browser-based toolkit for geographic data analysis.
It offers:
- Interactive Map Tools: Measure distances and areas directly on the map.
- Data Format Converters: Convert between TopoJSON and GeoJSON formats seamlessly.
- Coordinate Utilities: Perform conversions and other coordinate-based operations.
No sign-up required, and all tools run client-side for privacy and speed.
Built with open standards and designed for developers, educators, and anyone interested in geographic data.
I think adding something like (or awareness of datum transformations generally) would make the tool harder to use for its intended audience. If you need the level of precision where tectonic plate movement matters, then you need professional level tools.
The worst distances you can expect are around 1.5m (comparing australia in 2001 when gps accuracy was improved to now). But that number can be hard to figure out if you don't have a tool that allows you to set the time of conversion :)
Could you how a decimal point in the distance measuring tool? I want to measure distances in my backyard from the satellite photo and the rounded number makes it hard to be accurate
I made something like this around 10 years ago to show wireless frequency coverage, luckily the country I was living in is small enough and close to the equator, I didn't support the curvature of the earth so I can't start to imagine how difficult it must have been to visualize it in the browser https://sourceforge.net/projects/waire/ in my case the earth was kinda flat lol, it was fun parsing the map data available back then and playing with SVGs, back then the rendering engine from Opera browser was unmatched
This is really cool! I was doing some research last year on OpenStreetMap and wishing that there was tools like distance measurement there by default. Thanks for building and sharing this!
im consistently surprised there aren't more tools like this. I also started playing with one earlier this year, and was pretty shocked how easy it is to get going with Leaflet as the backbone

Feedback and suggestions are welcome!
- type coordinate pairs by hand
- copy coordinates entered by clicking
otherwise, it's a great tool!
I also really like the scroll behavior there, no waiting for the previous zoom level to animate before it lets you zoom to e.g. city level
