This is a pretty supercool thing for curious minds, e.g. I just discovered (see the images on the right) that Charlotte Square in Edinburgh used to have a ying / yang thing going on.

"You can view the maps with a regular browser, but it's far easier to use the MrSid plugin (with which you might be familiar if you've ever used Ancestry.com) and Internet Explorer. Using the plugin you'll be able to quickly pan around each map quadrant and zoom in very close to the surveys as long as you don't mind waiting a few moments for the page to reload. The maps are easily-readable and fun to explore; I just wish the windows that displayed the maps were a bit larger."
