Hi, I just bumped into Wikimapia for the first time and am trying to learn their copyright policies. There is some data on that site I wish to use here on OSM (names of military bases) but I don't want to join the organization merely to ask this question: "Can I use data found in Wikimapia on OSM?"

Wikimapia is apparently proprietary and up to June of last year the data, even though it as an all volunteer project, was not available for sharing. Then they adopted a new Terms of Use Policy more like that of OSM. I searched their User Forum looking for an answer to my question but could turn up nothing definitive. I did learn that some OSM mappers have used Wikimapia data in the past because they included attribution in their tag info.

Does anyone have specific knowledge about Wikimapia data usage?

That they are using Google imagery on their site and OSM aren't allowed to derive from Google imagery suggests that Wikimapia can't be used.

I'm aware of their connection to Google but it is user supplied data I want to use, not Google imagery or Google data. It is complicated I admit. Maybe I better ask the question of them directly.

Hi AlaskaDave, You should follow Ed, if they’re data is based on Google, we should not add Google data to our own OSM data. If you’re able to follow the lead/name elsewhere for a conformation you’re free to add it to OSM. You’re personal observations are preferabel above all Greetz

Ed is absolutely right. It's not complicated: Wikimapia derive from Google, and Google's T&Cs expressly forbid the uses that OSM want to make of OSM data.

Richard (just to give you some background to this unequivocal statement - I've been involved in OSM since the first months, have devoted more time than all but a few to the copyright aspects, and have done research at the Cambridge law library into deriving data from aerial photography)

It is not possible.
I do not really have anything to support this statement, but last time I checked it was so.

Thanks.

There are three issues with Wikimapia data.

1) If it is CC BY-SA, it's incompatible with the OdBL.

2) If the "G" special condition is of any effect, it is not really CC BY-SA (although most attribution would meet their requirements)

3) It is not really CC BY-SA but is derived from Google's imagery without permission.
