Earlier today, I found [1] which - amongst other things which you might be interested in - calls out a venture [2] to establish a network of 'citizen scientist' type flood sensors across the UK. Their scheme looks to be a network of radio-to-Internet gateways which support a number of independently-deployed sensor nodes.

The published version has headings: Latitude, Latin name, Modern name and date of Roman foundation, Axis, Amplitude at solstice, Published research. Still no map, though.

You can see the potential for a similar wraparound even on e.g. the mask dips.
