I'm a little laxer than some, so if copyright permitted I might accept official government documents as sources. Probably not, in this particular case, but maybe. But it's not going to render, anyway, which would make it useful only to those who know how to use overpass-turbo. Maybe uMap is the way to go for this. Or a CSV file of co-ordinates fed through a bit of programming to produce a web page using Leaflet. Either way would give a slippy map with pins which can display text such as risk level. -- Paul
