that takes you back to a
specific place and time.
Basic Controls:
Geo Box Time Box Content
Mapping Across Time…
It’s Not
a New Idea
…And it’s not
Just about Historic
Maps

Economic Q: Why Hasn’t It Caught
On in OSM?
Plenty of other stuff going on
Including day jobs
Mapping today still unsolved
Many Hard Questions
Soylent problem:
History is… people!
xn + yn = zn
Why Now?
Increased Expectations
Tools getting
better Mapping & Web
Grasp always exceeds reach
Temporal Mapping Is HOT
What OSM Can Do Now
A lot!
Community support (OSM-H)
Tagging advice (Buildings)
Common
Environment (Rails port)
TAGGING
…aaaah, Tagging.
We love you so.

AUTHORING
Much can be done in OSM
Lots of historic geodata doesn’t “fit” into osm
Still a pain for
time series
Styling matters… same data, different
style = different story
