We’ve excerpted just a slice of a single view of Bombsight.org’s interactive map of the London Blitz. Our screen grab doesn’t  do it justice – no scrolling, zooming, no selection of time slices.  Check it out.

This is a project of the United Kingdom’s National Archives Image Library; we can imagine this map as a point of departure for other datasets, such us as overhead images of the damage and recovery. Compare this to one of the first iterations of the very first data map, Dr. John Snow’s mapping of cholera in London.
