Historical view of openstreetmap

ایہہ ؜12؍؜March ؜2013ء‬ English وچ «mapryan» لیکھ چھپیا گیا سی۔

All

Does anyone know if there’s a way to see a historical view of Openstreetmap? ie, for a given area, can I see how it looked in OSM 6 months ago compared to how it looks now?

Cheers

Mike

It’s possible, but not easy. You can download old planet files, but you’d have to extract the area you’re interested in, then render it, then compare it with what’s currently there.

Remember that you’d only be comparing what had been mapped then versus now – it’s not necessarily a record of how an area itself has changed.

Only found in the OSM wiki:

osm.wiki/Historical_Coverage

But out of date?

A further complication is that the rendering style changes, tags get deprecated and removed from renderer’s config, etc. So even with Jonathan’s hypothetical tool, you’d be rendering yesterday’s data with today’s style. Still, would be cool to have :)

That said, have a look at http://owl.apis.dev.openstreetmap.org/ : you’ll see recent changes in an area and can even see the old geometry by hovering your cursor over an item’s “back arrow” icon.

Thanks guys. Obviously not as easy a question as I thought
