Example for use[edit]

See: Image:Hildesheim-Hoher.Weg.Huckup.01.JPG

Syntax {{Location|Degree|Minute|Second|Latitude|Degree|Minute|Second|Longitude|Information attributes}}
Example {{Location|52|09|03.70|N|9|57|02.79|E|type:landmark_region:DE-NI_scale:5000}}


The example is for a landmark in the region Germany (DE), Lower Saxony (Niedersachsen NI). By scale you request the mapping program to render the map in a scale of 1/5000.) Information attributes on landmark and region should always be added. Scale is an optional parameter and is not necessarily required. To find adequate parameters for other regions of the Earth, please look at the project pages in the English Wikipedia (w:en:Wikipedia:WikiProject Geographical coordinates or in the German Wikipedia (w:de:Wikipedia:WikiProjekt Georeferenzierung).

Wikidata complaining about the location[edit]

Category:Bradleys Head Lighthouse has this statement

{{Object location|-33.853487|151.246664|Wikidata=Q897057}}

which is complaining

There is a discrepancy of 33 meters between the above coordinates and the ones stored at linked Wikidata item Q897057 (33°51′13″S 151°14′49″E, precision: 11 m). Please reconcile them. To copy Commons coordinates to Wikidata, click here

I get the coordinates from the Wikipedia article, I double-check them in Google Maps, I update the coords on Commons (the ones above). Still complains. So I "click here" as instructed. I login in, I run the tool it presents. The error persists. Now what? Kerry Raymond (talk) 23:20, 27 February 2019 (UTC)

  • Ignore Wikidata. It’s a useless GIGO machine with an atrocious UI. -- Tuválkin 23:57, 27 February 2019 (UTC)
  • @Kerry Raymond: I've just checked, and saw no error, so maybe you had a caching issue (try doing a page-purge). However, I have removed the {{Object location}} template, as the category page also has a {{Wikidata infobox}} template, which incudes the coordinates. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:28, 28 February 2019 (UTC)
    • Maybe the tool (which I don't recall having a name) should tell you to purge as it's a real time-waster sitting there trying to fix a problem if it isn't really there. And it should include instructions for installing the page purge gadget as I doubt everyone has it. Also, please don't remove the Object Location on Commons. At the moment, I am trying to connect up all the New South Wales State Heritage Register articles with their Commons category (or create a Commons category if photos exists but aren't in a category). Often the naming of files and categories on Commons makes it unclear whether or not they are the photos of a particular NSWSHR place, e.g. is Category:Narrandera railway bridge the heritage-listed railway bridge in Narrandera? Are the photos of St John Uniting Church in Orange the heritage-listed Uniting church in Orange? After a fair bit of investigation, I think they are for a different bridge and a different church. Indeed, I think the 3 photos in the bridge category are not even of the same bridge. I have to use every clue about locations of the photo, of the category, etc to try to resolve these things. If the source of ground truth is in the article, or the photo, or the commons category, it should never be removed from there just because it has been copied onto Wikidata. At the moment, I am seeing people systematically removing Commons Categories from WP articles with edit summaries that this information is already on Wikidata, but did those people know enough to be sure that was the right Commons category on Wikidata or are they operating on the principle of "the name is similar", a behaviour encouraged by by MixNMatch. Kerry Raymond (talk) 23:14, 28 February 2019 (UTC)
      • @Kerry Raymond: The problems arising from Wikidata’s initial inability to link between a Wikipedia article and a Commons category have recently become much less annoying and it’s almost trivial to ensure the correct interlinking is showing on both sides, by means of Wikidata. The manually filled-out {{Commonscat}} is replaced by «In other projects: Wikimedia Commons» on the sidebar (it can be used to override Wikidata, when really necessary). It’s good to see Wikidata working as intended, even if only after several years and a few million dollars. -- Tuválkin 07:24, 1 March 2019 (UTC)
    • A second question. I note that the error message related to a 33m difference and an 11m precision. For a lighthouse which has a relatively small footprint, 33 metres difference may be significant, but for heritage-listed lighthouses, we are often dealing with a lighthouse precinct consisting of the lighthouse, a lighthouse keeper's cottage, and other infrastructure, for which there are boundaries and the single coordinate will usually be a centroid and not necessarily the lighthouse itself, in which case 33m might be quite acceptable as a difference. Similarly I can't imagine that 33m is a meaningful discrepancy if you are talking about the location of something with a very large footprint, such as an abandoned mining town. How is it decided if a discrepancy is significant? Kerry Raymond (talk) 23:14, 28 February 2019 (UTC)
      • @Kerry Raymond: I’d guess it simply reacts to the values not being identical, without any attempt at considering scale and precision (which is okay, since Wikidata and Commons should have the same criteria and therefore any discrepany is an error, albeit small). -- Tuválkin 07:24, 1 March 2019 (UTC)
    • @Pigsonthewing: You did what? You actually removed the coordinates as stored locally in this project, trusting that the remotely hosted geolocation data will not get corrupted? You’re either haven’t been paying attention to what’s going on about Wikidata’s issues with low volunteer activity, peameability to vandalism, unreliable results, and opaque mechanism — or you’re willing to sacrifice the health of our content to prove a point. (A point which I agree with, in theory, but I value the practical aspect of having healthy data way more.) -- Tuválkin 07:24, 1 March 2019 (UTC)
      • I'm not going to respond to such hysterical, ad hominem nonsense. If you wish to have a discussion, rephrase your post more reasonably. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:11, 2 March 2019 (UTC)

We have 2 categories for pages with commons/wikidata geolocation discrepancies:

in both cases distance is measured between 2 location and divided by precision taken from wikidata. In the first category, there seems to be a clear mismatch, in the second one is more mild mismatch. Some places like country, city, national park, etc. should not use precise locations with sub-meter accuracy, so many issues are due to Wikidata "precision" field which should be fixed there. However a Lighthouse, statue, etc. could be very precise, so the most pressing issues is to reconcile locations of such objects. --Jarekt (talk) 20:34, 1 March 2019 (UTC)

Leading zeros[edit]

In this Template there shoud be integrated leading zeros in the E-W coordinates. East-West coordinates have 3 digits since they vary fom 0° to 180°. The print out in this example should be 016°54'25.16"

Object location25° 06′ 13.26″ S, 16° 54′ 25.16″ E Kartographer map based on OpenStreetMap.View all coordinates using: OpenStreetMap - Google Earthinfo

--Hp.Baumeler (talk) 10:05, 20 March 2019 (UTC)

I never see coordinates written in this format. For me, "16°54'25.16"" looks much more natural than "016°54'25.16"". Any other opinions? --Jarekt (talk) 00:29, 21 March 2019 (UTC)
In aviation and other fields where coordinates are crucial they are written with leading zeros to show to the reader that no number is missing. (See German page: Darstellung von geographischen Koordinaten.) The template already includes a leading zero within the minutes: --- 06'---! Coorinate-Minutes vary from 00 to 60 minutes, hence are expressed with two digits. The East-West degrees vary from 00 to 180 and hence should be written with 3 digits! --Hp.Baumeler (talk) 13:50, 23 March 2019 (UTC)
I can see a use for leading zeroes in numeric-only tabular formats, but with the proper symbols I don’t think they add any value. IMO the minutes & seconds are quite a different case from the degrees: they do frequently appear with leading zeroes, almost as often as in time formats, but I’ve very rarely seen degrees printed that way in gazeteers, maps, navigation manuals, or the like.—Odysseus1479 (talk) 23:13, 10 April 2019 (UTC)

Google Earth[edit]

Link doesn't work. It was very useful when it worked. It has been broken for weeks and no indication that someone will repair it this year. Until it works, this and other templates should use something else instead, such as Bing Maps. Jim.henderson (talk) 13:54, 9 April 2019 (UTC)

@Para:, Any chance Google Earth tool can be fixed? --Jarekt (talk) 18:20, 10 April 2019 (UTC)
Fixed. All it needed was a webservice start after WMF shut down the previous servers. --Para (talk) 20:14, 10 April 2019 (UTC)
@Jim.henderson: the links are to tools which are capable of displaying locations of other files. There is not tool to display them on Bing Maps or other map providers. --Jarekt (talk) 18:20, 10 April 2019 (UTC)

@Jarekt: @Para: thanks to both; that useful feature is indeed working well for me. Template:Geogroup still isn't working. Sometimes I think, every time something is repaired, something else will stop working. Jim.henderson (talk) 04:05, 11 April 2019 (UTC)

Target maintenance category - proposed name change[edit]

A CfD (Commons:Categories for discussion/2019/06/Category:Pages with maps) has been started which will require a change to this template. Please comment there regarding any possible impact on this template or pages that use it. Josh (talk) 22:14, 10 July 2019 (UTC)

Josh, neither {{Location}} nor Module:Coordinates sets that category. I think it is added by the Kartographer software itself. --Jarekt (talk) 02:32, 11 July 2019 (UTC)
Thank you for the clarification. Still, if anyone has input on the discussion I would encourage their contribution on the CfD. Josh (talk) 17:05, 11 July 2019 (UTC)
