The Tenuous Link

Although it's slow to use, this map from the Southampton City Council Building and Planning Department is fantastic if you zoom in to street level (try the second highest zoom). It has house numbers marked on, and lets you compare the size of your back garden to all the others down your street.

The "SVG" version is best (you get prompted to install a pluggin). The options take a bit of getting used to, but here's a hint - unselect the "Show Open Spaces" option and then the map reveals all the paths across the parks and the common. There are only two options for the size of the map in the browser window, which wouldn't be too bad if the map wasn't so painful to scroll.

The map also has the height above sea level marked on so we can work out how big a tidal wave is needed to reach Highfield, and for smaller waves, the map has a helpful options to highlight areas at high and medium risk of flooding. Obviously very useful.
