One of OpenStreetMap’s greatest advantages is that we don’t just give you a beautiful draggable map - we give you the data, so you can do what you like with it. Well, this weekend, that just got a whole lot easier.
OpenStreetMap now has an ‘Export’ tab, joining ‘View’ and ‘Edit’ at the top of the screen. It gives you an instant way to get the map data in a format you want.
Want a static map for your blog, without having to spend hours fiddling with JavaScript? No problem - just export in PNG or JPEG. Want a map for a book? PDF or SVG are the perfect formats - fully vectorised, so they look smooth on high-resolution printers at any scale, and are easy to restyle or edit. Want to play with the raw data? Get it in our easy-to-parse OpenStreetMap XML format. Here’s an example of a simple PNG streetmap generated in just two clicks.
