WWII Bombs in Nottingham : discovering local history whilst mapping

Last Saturday I showed 2 visitors how I mapped addresses (more on this later).

Infill housing, St Cuthbert's Road, Nottingham NG3

One little vignette stood out.

Perhaps I was too cryptic

Each of the above maps represents objects mapped on OpenStreetMap which have a tag which corresponds to a single word. Together they spell out a topical phrase:

• Happy. Actually name=Happy's as for some reason I had not spotted lots of name=Happy in Europe.
• 10th. A minor fudge, using tiger:name_base=10th and restricting it to Pennsylvania to reduce the amount of data returned.
• Birthday. A couple of retail places in Japan have name=Birthday.
• OSM, A real fudge, I used source:name=OSM (an interesting recursive defintition in itself) 

Happy 10th Birthday OSM!
