Goal: make the world’s most out of date map!
Been at this a looong time…
2009 – Frankie Roberto, Schuyler Erle,
Tim Waters presentations
2012 – SotM update
2013 – first hangout, rough site up in Mar
Since then, lots of single-timeslice projects
Long-time needs:
Time slider
Search
Why OSM as foundation for historical mapping
& crowdsourcing?
Huge OSM ecosystem
Editing tools
Shared database

Occidental Hotel
Start date: 1861
End date: 1882
Wikipedia: The first Occidental, which opened in 1861, was a
wooden building. Twenty years later, on September 26, 1881, it
held a memorial service for President James Garfield, who had
died five days earlier from injuries sustained when he was shot
in July. (link)
