The place to discuss geotagging and 23places in particular

23's support for gepotagging and our 'Place tagging'

Steffen Fagerström Christensen Team 23   September 26, 2006, 12:10 PM

We're working hard on a general interface to make geotagging and photo localization easy -- the interface will include a few different method of autotagging along with a feature that allows import from GPS unit. Most of it is coded, but it not quite ready to be released to the public yet.

One thing that we have released in
a) Maps on photo pages when the photos have been geotagged (such as "geo:long=9.6978 geo:lat=55.7994")
b) A special, magical 'place tag'. It works like this:

- Geotag one photo with a "geo:long=..." and a "geo:lat=..." tag and then give the photo a special "place:..." tag. For example, you could tag the photo: "geo:long=-77.03362", "geo:lat=38.89206", and "place:whitehouse".
- Now, whenever you tag a photo "place:whitehouse" you'll automatically geotag the photo as well. No need to remember coords, just remember the place.

Any feedback, as always, is welcomed...

that is great.

However I would prefer that the "geo:long" and "geo:lat" data not appear in the tag cloud.

And if I click ( here on "Show all photos", I get an error page!

Steffen Fagerström Christensen Team 23   October 20, 2006, 10:42 AM

Dunno about hiding actual tags. A more viable solution would be to handle places as something other than tags. We may do so over time, but for now we're looking for reactions on the small-scale implementation we've done now.

And sure, there are some dead links in the current flow -- basically, all we've done so far is:
a) The automagic "place:?" tags
b) Showing a map on the individual photo pages.
c) Showing an over-all map (/username/places)

(Apart from this we've been toying around with ways of automatically adding geographic data to your photos. It's not active at the moment, but here's a hint: Try signing up at

I guess this topic joins the one i launched about microformats here :

You could find some more informations about geographic positionning here :

excerpts : "Flickr now supports the geo microformat ( on all geotagged photos ( Within 11 days of launch there are now over 3M+ photos (as of 20060907) marked up with the "geo" microformat."

Philipp Mertens   January 31, 2007, 10:08 AM

Are there any news to geotagging and 23??
I would be pleased...

Daniel Isenmann   June 16, 2007, 04:32 PM

I have tagged my photos with geo:lat=... and geo:long=.... Everything is working, the map is displayed and it's cool this feature, but the places page doesn't appear. If I go to there comes only: " You haven't enabled 23places yet. Do it now!." But after clicking on "Do it now!", nothing changed, just redirect to tags-page. Have I something wrong?

Steffen Fagerström Christensen Team 23   June 16, 2007, 04:37 PM

Hey ise_80 -- could you give it another try?
We'd love to get your feedback about geotagging, since it's still very much at the "proof of concept" stage.

Daniel Isenmann   June 16, 2007, 04:42 PM

Great, thanks Steffen, now it works!!! :-D
If I can help in any way, let me know. I would like to help in geotagging...

Steffen Fagerström Christensen Team 23   June 16, 2007, 04:47 PM

Sure, I'll probably post calls to action in this photogroup when we get that far. For now, just start geotagging your own photos and remember to use the "place:*" tag.
In fact you can probably also geotag other people's photos if you want ;-)

cosmonautirussi   June 22, 2007, 10:53 PM

Thanks for working on that feature! I like geo-tags very much and would like to use them. - I put a photo to the pool where I have problems with it. Any suggestions what is wrong with my tags?

Daniel Isenmann   June 23, 2007, 10:08 AM

Hi, you must go first to, there will be a link to activate the geotag feature...Have you done this?

cosmonautirussi   June 23, 2007, 10:45 AM

Thanks Daniel! - This might have been the point!
- But while trying I once saw the map next to my picture... I just wasn't able to find out why. (I used the wrong coordinates. - After correcting them the map disappeared...)
- So: I activated "my places". The map is not visible for me now. - Any idea why? - Thanks so far! :)

Daniel Isenmann   June 23, 2007, 11:03 AM

No, that was my only idea....I have set your coordinates in my tags, they show Bremen, I think that was right, because of the other tag. But that's the only hint I can give you, that the coordinates are right, but I think, that have you know already....

Andreas Bucher-Mack   June 23, 2007, 02:14 PM


I've played with geotags.

I used this "geo:lat=49.3429" "geo:long="7.3550" with the 'Add tag'-Feature.

This is the output in the taglist:


When I delete one of the geo:long-tags, the map will disappear.

I've uploaded the example to the group pool.

This is only a hint. ;-)


astreim   June 23, 2007, 04:02 PM


that's maybe a really stupid question, but what is the easiest way to get the geo:lat and geo:long data for a place?


Daniel Isenmann   June 23, 2007, 04:06 PM

I do the following:
- go to
- enter location
- click on "URL to this map" (on the right top of the map)
- then there is in the URL the following: example : &ll=49.010402,8.393555
- that's are your coordinates, in this case geo:lat=49.01042 geo:long=8.393555

astreim   June 23, 2007, 04:23 PM

Thanks a lot, Daniel. Just put my nice polarbear on the map :-).

Steffen Fagerström Christensen Team 23   June 24, 2007, 05:35 PM

Hi guys,

I'm not sure if I can add much to the discussion at this point -- but one thing that's like to solve most problems with geotagging:
a) Never use more that one geo:lat and geo:long at once.
b) If things fail, delete your geotags -- and re-tag the photo.

For now, the 23 geotag support is basically a quick hack to allow us to build a base of geotagged photos before attacking the challenge correctly -- so some of these quirks are sadly to be expected. I hope this helps...

cosmonautirussi   June 24, 2007, 05:46 PM

Great! It works now! - To delete the tags completly has solved the problem! :) Thanks!!

Steffen Fagerström Christensen Team 23   June 24, 2007, 06:16 PM

Sure! It's very intuitive!

Fabien Basmaison   June 27, 2007, 06:06 PM

I was wondering if something like this would be possible: "place:Paris:Eiffel tower" to describe a place in a place...

I used it there, though:

nicht-jens   July 04, 2007, 07:34 AM

This is awesome, thanks. So in the future i might search for a place and get a list of all the pictures tagged with this location?

Also, will it be possible to tag albums instead of pictures (not limited to the geo-tag, but still)?

pregnantboy   July 09, 2007, 11:02 PM

So cool, it's a little bit slow the geotagging process but I'm confident for the future.

astreim   July 10, 2007, 05:59 PM


I found a cool tool - for Europe only - using google maps. You can enter an adress and just get the geodata:


Andreas Bucher-Mack   July 17, 2007, 05:40 AM

The Geocoder is nice, but I can't copy and paste the data. You can do this also with Google Maps. (searching for an address)
There I can copy the url.
I've written a Autohotkeyscript, that converts the url into the form "geo:lat=... geo:long=..." which I can paste into the IPTC-Part of a photo.
After uploading to 23, the page shows automatic the map. I'll write a howto for the script and will post it here.

astreim   July 18, 2007, 07:00 AM

Hi Andreas,

yeah, I found the same problem with the Geocoder. I would appreciate your script - I've never heared of Autohotkey before, but now I surfed the web and it looks very promising. Will try it later.


Andreas Bucher-Mack   July 18, 2007, 08:34 AM

Hej, Andreas.

Start using ac'tivAid. That's an autohotkey script environment with many 'ready-to-use'-Tools. It's an project of the german computer magazine c't.

astreim   July 18, 2007, 08:27 PM

That's a great tool. Still playing around with the scripts. And now I am waiting for your geo-script ;-)

Andreas Bucher-Mack   July 19, 2007, 08:09 PM

GeoTagMaker is ready but I can't paste it into a story. I think there are too many &s in the source. 23hq input-fields are secure. ;-)

I'll send it by mail until I've found a place for tutorial and download. (Somewhere on my website. :-) )

Corax   July 20, 2007, 01:10 PM

Hi, I've been wondering...
would it be possible and/or make sense to have a "geo:lon" tag, equivalent to or instead of the current "geo:long"?

Somehow I'm feeling... queasy... to have one tag in the three-letter-form of "geo:xxx", and the other in a four-letter-form of "geo:yyyy", especially when listed above each other:


Daniel Isenmann   July 20, 2007, 01:14 PM

I don't think, that it make more sense, because "lat" and "long" are the "official" short names for latitude and longitude...

Corax   July 20, 2007, 01:46 PM

"Official" by what authority?
for example.

Daniel Isenmann   July 20, 2007, 04:25 PM

"Official" by none authority.....but having geo:lon is something, I don't know, strange in my opinion. "geo:lat" and "geo:long" missing both only the tail "itude", it's much clearer (for me).

Corax   July 20, 2007, 06:03 PM

I understand that, and it's the reason why I suggested having both ":lon" and ":long" interchangeably and let the user decide which one to use for their tags.

Philipp Mertens   February 23, 2008, 11:35 AM

I am for the "geo:lon" tag so that I don't have to insert a "g" manually, but I can also live with the current version or the equivalent version.

Pablo I   December 13, 2010, 05:55 AM

I know it's been over two years since the last post on this thread, but I wonder if geotagging is still being considered for 23. I guess not, given that after all this time it hasn't been implemented.
I've successfully used the lat/long tags to display a map on some of my pics pages, but that is very different from geotagging, right?

cosmonautirussi   December 13, 2010, 11:15 AM

Hi Pablo!
Take a look at at some photos of this pool.
(Here is a direct link to one of mine: ). You can see the geotagging on the right side.


Pablo I   December 14, 2010, 02:07 AM

Hi cosmonautirussi,
thanks for the link. I've already used the latitude/longitude tags to do some "manual geotagging" on some of my pics (for example:, but it's quite cumbersome to have to do it that way. I mean, finding the place in Google Maps, copying the lat/long coordinates, and then generating the geographic tags for your picture.
I was hoping that work on some better implementation of geotagging (Ipernity has some nice geotagging, by the way, although I prefer 23 as a whole) was still going on, but it doesn't look like it. I understand that the team may have other priorities, but "full" geotagging would be a wonderful addition to 23's feature set.
