What not to map in OpenStreetMap

rweait's picture

We love to map. We love to provide correct, complete, comprehensive data for the OpenStreetMap® data base, and for the millions of consumers of that data, around the World.

And I'm walking around the neighbourhood, minding my own business1, when I pass the intersection of Waters and Stanley. Just a normal day, Wait. What?

I see these new street signs. Time to improve OpenStreetMap, right?


I'm not mapping this

"Waters and Stanley"? That's not this intersection. Those aren't Toronto, municipal street signs!

I'm not going to change this information in OpenStreetMap. The street signs are for a film set.

Waters and Stanley are a film set

In the rest of the image you'll see that the intersection is closed. There is a lighting boom truck, and the black tarpaulin is covering some camera equipment. A partial helicopter tail rotor is also visible, as the film set in question includes a "crashed" helicopter. Out of frame are various film set staff, security, and equipment.

Mapping guidelines

A great set of general mapping guidelines are to map things that:

  • are verifiable,
  • are permanent,
  • and are significant.

Since the film set will only be in place for a few hours, this information isn't "permanent" enough for me to include it in OpenStreetMap.

Happy Mapping!
