Welcome to the new home of the Boston Atlas.
The Boston Atlas has been updated with many new features. We have added a new Flash viewer and an improved Java viewer - both supported by a new open-source map server. We will continue to maintain the legacy Java viewer and server for the forseeable future. We hope that these improvements continue to make the Boston Atlas a valuable resource for the community.
