[Historic] Hello list & tagging historical details

[Jeff Meyer]

Hi Christian -

Right now, the current OSM infrastructure is very good for showing what is
here today.

I believe one of the goals of Historical OSM is to show what the world
looked like at any time in the past. Some of the problems with using the
current database are: how to remove objects that didn't exist 100 years
ago, how to draw objects that did exist 100 years ago, but are now gone &
covered up by other roads or buildings?

So, the goal of setting up a parallel OSM Stack (not just the Rails Port)
will be to set up an environment where we could edit maps for the same
place for multiple times and also serve tiles for multiple times. For
example, to show what cities and roads looked like in Burgundy after the
Treaty of Verdun or what the road system across France looked like in the
1800s, after trains, but before cars, etc.

I think the place to start, though, is to start working on the workflow of
using old maps for tracing information and picking some sample projects at
various locations around the world. Then, after learning by doing, we could
see what tools needed to be developed most urgently.

Does that help?

Regards,
Jeff
