The colors in this map of the United States indicate how recently each road has been edited
in OpenStreetMap: the oldest data in yellow, the newest in magenta, along a spectrum
from Charlie’s sinebow algorithm.
The recent bot edits expanding street names
stand out in the east.
The image comes from a tool I’ve been working on
for visualizing the OpenStreetMap GPS track collection for
a workshop at
State of the Map US next week.
It also turns out to be helpful for visualizing aspects of OpenStreetMap
itself, which Tom and I are doing for the
OpenStreetMap Data Report session on Saturday.
