Hi All,
I have a trivia for you license-interested/competent folks. Say I have a
recent aerial photo coverage of a really nice town that I'd like to use to
digitize features, is there an issue if the photo is private (city-owned) ?
The way I see it is that if I'm digitizing a point/line/polygon and
assigning it attributes, I'm really photo-interpreting so the data is
"mine". Of course the underlying photograph helped, but it's not data per
se. Any arguments/counter arguments or real legalese pointers ?
The policy of the OpenStreetMap community is that we hold ourselves to
a very high standard when we respect the works and rights of others.
And so any action that is not clearly and explicitly permitted by a
rights holder, is not permitted as a source for OpenStreetMap
contributions.
As an example, we have permission from Bing / Microsoft to use Bing
imagery for tracing / photo-interpretation. So we can do that.
We don't have permission from Google to use Google aerial imagery for
the same purpose. So we don't do that.
Please get permission from the rights holder to use that image for
photo interpretation.
Hi Richard,
Fair enough. I wasn't going to digitize features in a whole town
without some sort of permissions. Plus, I won't be alone anyhow. The
real question is how does that translate in the digitized features ? Do
I need to add a feature "attribution" attribute mentioning where from it
was digitized or is just getting the "you can go ahead and trace" go
from the photo owner good enough a proof ?
In my opinion it is neither accurate nor fair to say feature X "belongs"
to whoever is the owner of the base data out of which it was *created*
through the act of photo-interpretation. Technically, the feature's
attribution really is that of the digitizer. This doesn't mean I want
to go ahead and pretend I have drawn a feature myself as I would do over
my own GPS traces, but I sure wouldn't attribute a feature I drew
(potentially compensating for radial displacement etc. while digitizing)
to the owner of a photograph. How do we go about this so that is fair
to both the "base data" provider and the "real data" (i.e. feature)
provider ?
Thanx,
Yves
