Boston's Changing Map

Mapbox has created an interesting visualization of how Boston's geographical footprint has changed through history. Coastlines of Boston provides two different historical views of Boston, as it looked in 1788 and 1898, and allows you to compare these views to the map of Boston today.

The map is actually a neat demonstration of what can be created using Mapbox Studio's new dataset editor. The dataset editor allows you to add and edit geospatial data within Mapbox's existing browser based style editor.

The dataset editor allows you to add data to your maps by uploading CSV or GeoJSON files. It also allows you to add or edit data directly on your maps using point, line, and polygon editing tools. Once you have uploaded and edited your data you can then save the data to your map tilesets.

The Coastlines of Boston map was created by importing historical maps of Boston into Mapbox Studio and then drawing around the historical coastlines. Once the coastlines were traced they were then saved as a map tileset. You can read more about how Coastlines of Boston map was created on the Mapbox blog.
