The recent maps of tranquility published by the CPRE are a great resource for teaching about the concept of urban sprawl.

I added a couple of the maps as overlays in Google Earth. By turning transportation layers on and off the effect on tranquility for different types of roads, railways and airports is revealed. It’s interesting to note that motorways are often less disturbing than A roads.

The site has some other useful resources such as the “what does tranquility sound like”? noises.

Hey Noel, we folks here at the Campaign to Protect Rural England (CPRE) are mightily impressed with the speed and finesse with which you processed our Tranquillity Map data into Google Earth. Now we’re thinking about how we can make best campaigning use of our Tranquillity Maps GIS data set, and perhaps do something similar with our light pollution maps data, we hope we can open communications channels with you about interfacing with Google Earth. I have sent a longer message around these issues to you via your ‘Contact Me’ web form. Looking forward to a geographically expansive conversation, Tim Jones, web.dev volunteer, CPRE HQ
