Dimensions is a cracking little site from the BBC which takes important places, events and things, and overlays them onto a map of where you are: http://howbigreally.com/

Dimensions is an experimental prototype for the BBC designed to bring home the human scale of events and places in history. The D-Day landing beaches measured from London to Norfolk in the UK. How far would the Titanic stretch down your street?

Dimensions simply juxtaposes the size of historical events with your home and neighbourhood, overlaying important places, events and things on a satellite view of where you live. Certain “Dimensions” can be transformed into short walks, so you can get a physical appreciation of the distances involved.

See how big the Gulf oil spill is(below) or the journey of a Mars rover compared to your own postcode, superimposed into a Google Map.

Gulf Spill

This would be of interest to History, Geography and Science teachers – a handy bookmark to have.
