This is an invitation to use Mapjunction!

It’s a free web tool for map lovers and history enthusiasts. In Mapjunction you can compare any two maps from Boston and environ history. You’ll see almost 400 maps and aerial photos that are the result of combining about 3000 individual maps and aerial scans. Most of them cover the North End.

*Advertisement*

Just move the green wand from side to side to uncover history. Move the wand up and down to change opacity, and use the side bars to pick any map, aerial or atlas to explore.

The original Mapjunction was developed 17 years ago by Bill Warner in collaboration with the Boston Redevelopment Authority, the Boston Public Library and the Norman B. Leventhal Map Collection, and we are now launching a completely new version based on open source tools.

Here are some cool examples of what Mapjunction can do:
1. This one clearly shows the destruction of Boston West End using aerial photos from 1952 and 1969.
2. Check out these North End Atlas map from 1917 on top of today’s aerial.

We’d love to know what you think – use the Feedback button for that.
