Hello Gilles,
Hi Kolossos
you can use additionally also:
http://wiki.openstreetmap.org/wiki/Key:image
So you would have links in both direction.
I am aware of this opportunity but I'm not a big fan of it. Mainly
because there could be more than one picture documenting an object.
Do you want to use Geocoding? All Smartphones have GPS, but you need a
feature to adjust the position, and an camera-app with this feature
would be very helpful.
In its current state, ImageInOsm do add geolocation data to the picture.
See "machine tags" on this test image for example:
http://www.flickr.com/photos/31379880@N05/9615798128/
We're not really clear about which position should be stored in the
image: the osm object position? the camera position? I tend to think
that the latter is more consistent but I've to admit that the former is
currently implemented...
I'm not sure to understand what is a "feature to adjust the position".
Do you mean that the user could take a picture and override GPS lat/lon
by pointing a map? That could be fun, indeed. But our purpose is to
better document the objects which exists in the OSM database, hence the
OSM id.
I'm a member of Wikimedia Commons community. I'm relatively sure that
this community will be sad if someone uploads tons on pictures where you
only see housenumbers. Thats what mappers doing.
Sure, a common photomapping practice is to shoot many pictures quickly,
leading to poor quality images (a sort of "disposable" images). And I
agree with you, sharing such pictures is pointless.
But, aside from this practice, I'm convinced that it would be desirable
for any mapper to have access to a pool of good-quality, well-arranged
pictures.
Suppose you are a specialist of, say, botany. You notice an area where a
user put some natural=tree nodes. It would probably be useful for you to
find attached pictures so that you could add species=*, denotation=*,
etc based on your botanical knowledge.
This is the rationale of ImageInOsm: documenting OSM object in order to
improve collaboration.
Each picture on Commons also need a description, category and so on.
This makes a lot of work.
I'm currently exploring Commons. I know that uploading a file is not as
trivial as Flickr (that's one of the reason Flickr has been implemented
first). I was about to post my technical questions on mediawiki-api
mailing list. I'm not sure of the preferred way to contact the WM
Commons community... Do you recommand a mailing list or a forum?
I like the idea of a cooperation between OSM an Wikimedia, but I see
Commons only as place for a selection of pictures that mappers make.
Commons is also without your project on a good way to become a media
garbage dump.
So please give the user a chance to make a selection for an upload to
Commons. If you want to go an other way, please discuss this with
Commons community.
Sure, I want to discuss this with the community, don't worry about this.
And I also see Wikimedia Commons as a well-maintained repository of good
quality media.
But, if this WM Commons backend is implemented in ImageInOsm, we will
not be responsible of what users upload under their own account. Keep in
mind that it is possible to upload garbage through the regular web
interface as well. The contributor is responsible, not the tool (and not
the tool's maintainer either).
Wikimedia Commons supports with over 3.5 Mio pictures also geocoding:
https://commons.wikimedia.org/wiki/Commons:Geocoding
Each geocoded image gets also a link the description page to an OSM-map.
(I'm the maintainer of this map-frontend.)
Example map:
https://toolserver.org/~kolossos/openlayers/commons-on-osm.php?zoom=16&lat=51.05&lon=13.73
So geocoding is long-time stable, working for years and I can't see a
benefit by using a reference to in-stable OSM-ID's. Perhaps you can
explain the benefit you see.
Yes, unstability of OSM-id is a problem, with no simple solution
unfortunately. But I still think that there is a value in linking a
picture to its featured OSM objects. Geolocation (even associated with
compass direction) is not as powerful in my opinion.

Gilles Bassière
