Open Source Tools

For 20 years, Stamen Design has been part of a thriving data visualization and cartography community. We are happy to give back to that community through our open source maps. These projects use OpenStreetMap data as a foundation to explore a variety of map designs through our publicly available map tiles. These map tiles have been used hundreds of millions of times by people around the world. You can download our open source map tiles for your own project below.


These high-contrast B+W (black and white) maps are featured in our Dotspotting project. They are perfect for data mashups and exploring river meanders and coastal zones. Available in six flavors:standard toner, hybrid, labels, lines, background, and lite.


Orient yourself with our terrain maps, featuring hill shading and natural vegetation colors. These maps showcase advanced labeling and linework generalization of dual-carriageway roads. Terrain was developed in collaboration with Gem Spear and Nelson Minar. Available in four flavors: standard terrain, labels, lines, andbackground.


Reminiscent of hand drawn maps, our watercolor maps apply raster effect area washes and organic edges over a paper texture to add warm pop to any map. Watercolor was inspired by the Bicycle Portraits project. Thanks to Cassidy Curtis for his early advice.

Burning Map

The roof, the roof, the roof is on fire! These “heat maps” use toner-lines as the foundation on which to draw fiery animations. It’s our way of showing that maps don’t have to lie still on the screen anymore, and that we can use the whole world as a canvas for interaction and movement.

Trees, Cabs & Crime Maps

This project started off as a weekend hack and ended up in the Venice Biennale. This map combines three data sets (street tree locations, taxi cab GPS positions, and crime reports) with subtractive blending to reveal halftones hidden in the urban fabric of San Francisco.

Mars Map

Yes, Mars. The Mars Orbiter Laser Altimeter, or MOLA, is an instrument on the Mars Global Surveyor (MGS), a spacecraft that was launched on November 7, 1996. The MOLA dataset also contains height data, which we’ve made into a 3D contour map.

Field Papers

This tool helps you create a multi-page atlas of anywhere in the world. Once you print it, you can take it outside, into the field, to record notes and observations about the area you’re looking at, or use it as your own personal tour guide in a new city.
