Subcategory bins[edit]

We have half a million pictures now, with coordinates but no way to find the ones that were made in places we know. Presumably thousands are near my home town or other familiar places, but which ones? There should be a bot putting them into subcategories according to long-lat bins.

Maps with locations[edit]

It would be easier to categorize if people could choose photos from regions they know (as already mentioned above). The map tools should help, but none of them seems to work - the Google tool returns just blank page, the OSM tool opens a map with a note "sorry, no data to show".

Exactly. The tools in the Geogroup box don't work because they are overloaded. They can't handle hundreds of thousands in a category. It seems reasonable to suppose they could work with hundreds or maybe thousands. There are various standard systems to sort coordinates into hundreds of zones, or thousands or even millions, including:
Millions of course would be too many. Anyway I am confident that if all these are found to be unsuitable for making automated zonal categories, others can be used. Jim.henderson (talk) 02:42, 21 February 2018 (UTC)
This tool https://tools.wmflabs.org/wiwosm/osm-on-ol/commons-on-osm.php is able to display a self-limited number of images in a chosen map (if you zoom in, new markers may appear). Perhaps the same logic could be used for the osm4wiki tool? JiriMatejicek (talk) 06:58, 4 April 2018 (UTC)

Clearing this category[edit]

I have put some suggestions on this category in the Village Pump: https://commons.wikimedia.org/w/index.php?title=Commons:Village_pump&oldid=288510185#Category:Media_with_geo-coordinates_needing_categories but with no reaction. Maybe somebody will notice it here... JiriMatejicek (talk) 06:59, 5 April 2018 (UTC)

I see no sign of anyone but us two. Another idea would be a semi-automated process that would feed us a latitude band, working eastward or westward from some longitude. Or vice versa. I have no idea whether any of the existing automation tools could be made to do that. Jim.henderson (talk) 00:03, 7 April 2018 (UTC)
Are there no tools that automatically convert the coordinates to a specific place on the planet (country, city)? --Fractaler (talk) 18:10, 7 April 2018 (UTC)
Obviously algorithms have been written for other contexts. When I snap a picture with my Android phone and upload by the Commons app, it suggests categories of several nearby points of interest, presumably based on the EXIF coords. I have no idea how difficult it would be to incorporate this feature into a Commons bot or other tool.
However, breaking news, in the past few minutes I discovered the incategory parameter of our Wiki search box. A search for
incategory:"Media with geo-coordinates needing categories" 40°30 74°
returned a load of pictures with about 10% falling into my New York and New Jersey area of interest. This of course is far from pure, but it's also richer pickings than I've obtained by any other method, thus far. Perhaps someone who has properly studied Wiki Searching can suggest improvements.

Thanks for the tip, I've found a few this way. JiriMatejicek (talk) 09:58, 11 April 2018 (UTC)
Minor refinement:
incategory:"Media with geo-coordinates needing categories" 40°30 73° 59
gives majority in the western part of New York City. I intend to use it repeatedly, decrementing the minute number gradually, and later apply it farther west. If hundreds of us did this for the various places we know, we could clear the category in several months, unless for some reason there is a large number of pictures for which this method will not work. Obviously hundreds of us will not do it anyway, but it's a pleasant thought. Jim.henderson (talk) 21:38, 12 April 2018 (UTC)
Two more options (you may have used those already, but just in case):
As people often shoot in a specific area, you can search for uncategorized images from a given user - e.g. this guy has lots of photos from Algeria https://commons.wikimedia.org/wiki/Category:Photos_from_Panoramio_ID_5095076_needing_categories. Just replace his ID with one from author whose images you have already located in your area.
Also, searching for keywords (city, town, county) in different languages worked for me. JiriMatejicek (talk) 10:40, 16 April 2018 (UTC)
P.S. I've just found that option 1 as described above works only for some IDs. It worked for two that I tried, so I assumed it's universal, but it's not, sorry. Nevertheless, there is a possibility to search for images by a specific user simply by his/her name. JiriMatejicek (talk) 19:09, 16 April 2018 (UTC)
Splendid; now we've got a few different ways to use the "incategory" search feature. I figure Commons ought to have a more explicit "search in this category" button, but it doesn't, so we can use this option plus partial coords or author ID or keywords in different languages, or any of those in combinations. The author and keyword methods presumably are not limited to this geotagged category, but of course they ought to be used here. Maybe we should try to assemble this into a brief, clear instruction to go in the header of the cat. Jim.henderson (talk) 14:12, 18 April 2018 (UTC)
