== Transcluding missing modules ==

can we fix [[Special:WhatLinksHere/Module:Location map/data/Africa]] and similar (currently redlinked modules) in the new module version?  if not, we should revert to the old version. [[User:Frietjes|Frietjes]] ([[User talk:Frietjes|talk]]) 13:27, 14 March 2014 (UTC)
: also, if the plan is to simply create these missing modules, we need to have a plan for how we preserve attribution when the are copied. [[User:Frietjes|Frietjes]] ([[User talk:Frietjes|talk]]) 13:34, 14 March 2014 (UTC)
::The way the code works is it tries to transclude [[Module:Location map/data/whatever]], and if it fails, it uses [[Template:Location map whatever]] instead. This seems fine to me, and I'm not sure why it would need to be changed. Is there a concern with transcluding nonexistent modules? [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 15:45, 14 March 2014 (UTC)
::: a few questions: (1) where was the switch to lua and new code design discussed? (2) if there is no answer for question 1, then where is the performance comparison between the old and new version? (3) if there is no answer for question 1, what are the benefits for switching to lua?  (4) does the new module strip spurious whitespace in multiple-pin invocations, (5) what happens if an editor sees a redlinked module, clicks on it, and creates something non-functional? or have all the location maps been converted and given the same protection level as the templates? (5) why were some templates moved to an attribution page without redirect, and others with redirect? [[User:Frietjes|Frietjes]] ([[User talk:Frietjes|talk]]) 15:57, 15 March 2014 (UTC)
:::: 1. It wasn't. 2. The new code is about 3 times as fast ([[Template:Syrian civil war detailed map]] went from about 30 seconds render time to about 10). 3. Mainly performance, also cleaner code. 4. I'm not sure what you're asking. Can you give me an example? 5. That is a concern. Right now, that could cause damage. I'll work on a solution to that. 6. None of them should have redirects. I tagged most of them for deletion, but I may still have some more to do. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 16:22, 15 March 2014 (UTC)
::::: I am definitely concerned that this was not discussed prior to rolling it out.  There should be at least the appearance discussion before changing such widely used templates.  Transcluding missing templates is also a concern, we should do something about this.

::::: With regard to item 4, see [[Template_talk:Location_map#Location_map_code_error.3F|this thread above]].  We should not orphan the redirects in the near term, unless they have zero transclusions. Just my 2 pence.

:::::: They have 0 transclusions. The job queue just hasn't caught up yet. Re 4, blank lines do break it, but since they broke it before, I'm not overly concerned right now (though I can fix that easily now). Regarding transcluding missing things, if needed, I can change the code to do an equivalent of a #ifexist before trying to load, but what's the benefit of that? Is there a database report containing redlinked templates that this is filling up? [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 21:19, 15 March 2014 (UTC)
::::::: Note, 0 transclusions in article space is not the same as 0 transclusions.  Yes, there is a database report for redlinked templates that this is filling up. The benefit of an ifexist check would be to not transclude missing modules.  I thought that much was clear in the thread above :) [[User:Plastikspork|Plastikspork]] [[User talk:Plastikspork|<sub style="font-size: 60%">―Œ</sub><sup style="margin-left:-3ex">(talk)</sup>]] 21:37, 15 March 2014 (UTC)

== Location_map templates deleted ==
Several admins circa 15 March 2014 have deleted some of the nation/region templates of [[Template:Location_map]] (changed to use Lua modules), which might be needed to format prior revisions of pages with maps. Specifically:
::* [[Template:Location_map_Belgium]] - deleted 15 March 2014
::* [[Template:Location_map_Italy]] - deleted, recreated 6 April
::* [[Template:Location_map_USA]] - deleted 15 March 2014
::* [[Template:Location_map_USA_Alaska]] - deleted 15 March 2014
Various admins have deleted/moved those templates and /doc subpages. In particular, [[Template:Location_map_Italy/doc]] needs to be unmoved or undeleted. There might be other mapper templates which were also deleted. The migration of {Location_map} to Lua has caused problems of "{{color|#AA0000|'''Script error'''}}, and is not portable to all browsers. Remember, Lua errors do not kill an entire article, but kill the whole template, whereas markup-based templates could display partial results (such as a map with error message for the user, but Lua shows "Script error" and no clue why). Currently, [[Template:Location_map_all]] is/was the faster, portable template to quickly display maps in rectangular coordinates on any browser, but it uses the map helper templates. -[[User:Wikid77|Wikid77]] ([[User talk:Wikid77|talk]]) 15:19, 6 April 2014 (UTC)
:Why do those need to be undeleted exactly? What articles specifically have script errors because of the Lua migration? [[Template:Location_map_all]] was moved to sandbox as a result of TfD. Those old templates are unused and should stay that way. Any benefits of any of your several forks of this template can and should easily be applied to the module, though I still have yet to see one that's not already applied. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 15:54, 6 April 2014 (UTC)
: To the reason given in the first sentence there is no need to 'format prior revisions'. I understand what you mean - as templates, categories, images are moved, renamed and deleted there's no way to fix old revisions of articles that still include the old versions. But that is not a problem we should be trying to solve as it's essentially unsolvable. The revisions primarily exist for attribution, as when you look at the diffs of an editors contributions or a page history you need both versions of the article to diff. They are also occasionally useful for content, such as content that was deleted for lack of notability but sources can now be found. But these previous revisions aren't meant to be read as articles, and expending effort fixing problems with them is essentially wasted effort as most problems can't be fixed so they'll never be of article standard.--<small>[[User:JohnBlackburne|JohnBlackburne]]</small><sup>[[User_talk:JohnBlackburne|words]]</sup><sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 16:09, 6 April 2014 (UTC)
::Further, the claim that previous revisions break at all is completely wrong. Old revisions of pages use the latest revision of [[Template:Location map]], not the version that existed when they were saved, so the module data works fine with them. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 16:13, 6 April 2014 (UTC)
::: The prior page revisions which use [[Template:Location_map_all]] will break when the helper templates have been deleted. You obviously do not understand the situation, and you need to stop deleting templates which have been developed over the past 8 years. Perhaps 8 years from now, you will have a better understanding. -[[User:Wikid77|Wikid77]] ([[User talk:Wikid77|talk]]) 16:35, 6 April 2014 (UTC)
:::: Then we can recreate [[Template:Location_map_all]] as a redirect to [[Template:Location_map_many]] for the very few pages that ever used that. And besides, as {{u|JohnBlackburne}} said, it's not a big deal if they break. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 16:45, 6 April 2014 (UTC)
:::: And don't say I'm deleting templates. Your templates were deleted because consensus at TfD was to delete them. The community deleted them. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 16:46, 6 April 2014 (UTC)

::::I understand it perfectly well, as I made clear in my first reply. As I explained 'fixing' old revisions is not possible and not something editors should waste time on. Articles, images, categories, are deleted or moved without redirect every day. We fix problems this causes in live articles, but can't fix old articles. This is in some ways a feature: the red links help remind readers, if they stumble on an old revision as they're sometimes linked, that the page is out of date. They can also follow the redlink to read the log entry to see why, use 'What links here' to find any discussion or notice, often (in the case of the template) the current alternative they should be using.--<small>[[User:JohnBlackburne|JohnBlackburne]]</small><sup>[[User_talk:JohnBlackburne|words]]</sup><sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 16:48, 6 April 2014 (UTC)

{{ping|Jackmcbarn|Wikid77|JohnBlackburne}} Jackmcbarn has asked me to look into this dispute as a neutral third party. I can see several points under discussion here, but in situations like this I've found that it's easiest to deal with one thing at a time. So let's start with the thing that I thought stood out the most - the question of whether the Lua migration of {{tl|Location map}} generated script errors. Obviously, we want to avoid script errors. But equally, we shouldn't avoid using Lua because of the mere possibility that script errors might occur. There are various ways of avoiding script errors, and to me it seems premature to stop using [[Module:Location map]] without considering any of them. Wikid, is it just the possibility of generating script errors that you are worried about, or did you actually see script errors generated on any pages? Were those script errors in the current revisions of those pages, or were they in previous revisions? Once we are sure of the facts here, I think it will be a lot easier to deal with the rest of the points that have been raised.

== Support for any browser ==
Another issue, for {Location_map}, is positioning the marker correctly for any browser, such as [[IE7]] which has required the attribute "line-height:0" when setting the div-section position of the marker. The alternative [[Template:Location_map_quick]] uses that setting, as discussed in 2011, to set "line-height:0" and will position the marker very accurately on the MSIE browsers, as well as Firefox. -[[User_talk:Wikid77|Wikid77]] 17:10, 7 April 2014 (UTC)
:This discussion is a worthy one to have, but let's wait until we have resolved the script error issue first.

== Avoiding script errors ==
I see [[User:Jackmcbarn|Jackmcbarn]] has been writing [[Module:Location_map]], and I had not viewed the source code earlier. I think we need to check calculations and invalid numbers in the lat_deg & lon_deg parameters, without showing script error (which has been fatal to omit the entire map, with no warning messages to the user). A possibility would be to attempt to auto-correct invalid digits, or assume an invalid latitude (or longitude) is the mid-point between the map's extreme values. To just show "Script error" would be much worse than a map with an invalid-expression message, and it would be good to alert the user with the caption, "<sup>[fix&nbsp;latitude]</sup>" or such in the map's caption.

: Yes, one shows '''Script Error''', the other an error. But click on Script Error and you see the error in a popup, with a precise error and stack trace, much more useful for tracking down the problem. Mostly though for ordinary editors either works to let them know there's a problem and to check the parameters. Editors aren't expected to know Lua debugging or parser error parsing (and parser functions often don't produce an explicit error, they just show the wrong thing). For most the best thing is point out there's an error to get them to check the parameters. For technical editors and those actually testing the stack trace is far the more useful of the two.--<small>[[User:JohnBlackburne|JohnBlackburne]]</small><sup>[[User_talk:JohnBlackburne|words]]</sup><sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 17:24, 7 April 2014 (UTC)

:Thanks for the reply. It is certainly possible to generate a more meaningful error message in this situation. For example, we could check whether the longitude variable exists before we do any arithmetic on it, and if it doesn't exist we could raise an error like 'longitude value "17.x" is not a valid number'. If we want, we could also make this a wikitext error rather than a script error, although that may require some re-engineering of the module. Wikid, would you be satisfied with a script error that contains a more informative error message after you click it, or would you prefer that the error message be a wikitext error? — '''''[[User:Mr. Stradivarius|<span style="color: #194D00; font-family: Palatino, Times, serif">Mr. Stradivarius</span>]]''''' <sup>[[User talk:Mr. Stradivarius|♪ talk ♪]]</sup> 18:36, 7 April 2014 (UTC)

:: I think any use of "Script error" (even if linked to Lua diagnostics) would be trouble for the end-users, so I suggest to use autofixing of invalid parameters, to display a map with partial marker data; see below: "[[#Autofixing map parameters]]". -[[User_talk:Wikid77|Wikid77]] 05:21, 8 April 2014 (UTC)

=== Autofixing map parameters ===
A map marker can be autofixed to overcome some cases of invalid latitude, longitude or other parameters, as "robust" operation. Showing an invalid map as "{{color|#AA0000|'''Script error'''}}" is likely to confuse the end-users, especially if the invalid map data was an accidental "drive-by" glitch by another user who intended to change some other part of the page, but mistakenly botched the map parameters. The goal is to show the map with an autofixed marker, if possible, where even a newcomer might be able to write a nearly correct map, while not understanding the exact parameters to align markers "perfectly" with labels.

The example below shows a proposed {{tl|Location_map/new2}}, where the invalid longitude "17.x" is auto-trimmed to "17." to show the map marker, slightly off-course, and avoid "Script error" caused by "tonumber(degree)" returning "nil" for invalid numbers.

|-
|}
In the above example, the invalid data "17.x" is auto-corrected as just "17." with the superscript note "[fix long=17.x]" to remind the user of the problem. In general, I think invalid numbers could be autofixed digit-by-digit (by Lua gsub()?), such as replace letter "o" as digit zero "0" or letter "i" as digit one "1" or perhaps letter "x" as "5" then check the result against the map's edges for the valid range of longitudes, and when an autofixed number is outside the range, then use range/2 to autofix an invalid coordinate as half-way (center) of the specific map, plus show "[fix__]" in the map's caption. A previous common glitch in many maps for the past 8 years has been invalid "px" in "width=180" but {Location map} already autofixes "180px" as being valid "180" while "width=180x" would show fatal Script error, and could be autofixed as "180" or default "200" when the "width=#$%" cannot be deciphered. Because Lua is so fast, then autofixing can be run in a tiny fraction of a second while adjusting several parameters. -[[User_talk:Wikid77|Wikid77]] 05:21, 8 April 2014 (UTC)
:I think that type of autofixing would be a little bit too aggressive. I'd rather strip out everything except numbers, "-", and ".", then parse whatever's left as a number. [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 12:39, 8 April 2014 (UTC)

:Wikid, one thing I would add to this is a tracking category - this would enable users who know the template syntax to patrol pages containing errors. — '''''[[User:Mr. Stradivarius|<span style="color: #194D00; font-family: Palatino, Times, serif">Mr. Stradivarius</span>]]''''' <sup>[[User talk:Mr. Stradivarius|♪ talk ♪]]</sup> 13:36, 8 April 2014 (UTC)
:: Agreed that a tracking category could be used to help spot the rare typos, as with the [[wp:CS1]] cite templates where users leave invalid cite parameters in 20-50 more pages everyday, despite the {{color|#990000|''cite's glaring red-error messages''}} which should cause people to immediately fix cite errors, but instead had been left in 9 thousand pages (1-in-240 pages) all year (2013, viewed up to 5 million pageviews), until fixed by cite gnomes. -[[User_talk:Wikid77|Wikid77]] 14:32, 8 April 2014 (UTC)

As with citations autofixing seems a bad idea: make the errors obvious and glaring, so they get fixed as soon as possible. Just point out there's an error - it seems pointless writing code to handle all possible errors as no matter how clever and complex the code editors will always come up with more ways to break things. Error messages could be more friendly but mostly there should be errors encouraging editors to check their code.

Besides this is very different from citation templates. Errors in those appeared primarily due to the Lua transition flagging so much more of them. There's been no comparable transition in this template. Citation errors are often rather subtle - deprecated parameters, mispellings - so the template still works. A map either works or it doesn't. And maps are part of the content, not necessary but largely ignored footnotes shunted to the bottom of the page. I would think editors very rarely add a broken map to an article - they'll want to see if it works and when it doesn't work fix it immediately.

=== Real-life examples of script errors ===

So we have now established that under some circumstances, the module may produce a script error whereas previously the template would have produced an inline error. However, it is not yet clear exactly how serious the problem is. One part of my original question was about real-life examples of script errors. I was concerned about this due to Wikid mentioning [https://en.wikipedia.org/w/index.php?title=Template_talk:Location_map&diff=603014372&oldid=602801267 here] that "''The migration of {Location_map} to Lua has caused problems of Script error''". Wikid, could you clarify where you saw these script errors? Were there any script errors present in any articles after the migration? — '''''[[User:Mr. Stradivarius|<span style="color: #194D00; font-family: Palatino, Times, serif">Mr. Stradivarius</span>]]''''' <sup>[[User talk:Mr. Stradivarius|♪ talk ♪]]</sup> 06:21, 8 April 2014 (UTC)

::::::: Regarding user-facing errors, Lua modules themselves have an "Allow saving code with errors" box, unchecked by default. Would something like that be useful outside of module space (not concerned about implementation, just about whether it would be a net benefit or not)? [[User:Jackmcbarn|Jackmcbarn]] ([[User talk:Jackmcbarn|talk]]) 23:33, 8 April 2014 (UTC)
{{od}} An interesting idea. I like it for modules - a non-compiling module is no use to anyone – but I suspect it might cause many more problems with articles and so be strongly resisted. Article errors are far more diverse - Lua errors, parser errors, wikimarkup and HTML errors. And editors can easily introduce them as they work on an article. References in particular are often assembled at different times to the article, because the editor does not have access to all the sources, or does not have complete information. Sometimes errors arise when section editing, when you can't see the rest of the article. Again this is often a problem with references - removing a named one, unaware it's used in another section, for example.

It would significantly slow down editing too. If it checks for errors before saving then it has to parse and render the page, before doing it again after the page is saved, so rendering the whole page twice; for a large page that could take a minute or more. This would happen whether or not there are errors.

So the way it works now I think is fine. Show the error if possible, in red so it stands out. But leave it to editors to recognise them and fix them. With Lua's better error reporting it should be easier to spot errors as they're generated and so quickly fix them, and it's also now much easier to find and fix errors left in articles.--<small>[[User:JohnBlackburne|JohnBlackburne]]</small><sup>[[User_talk:JohnBlackburne|words]]</sup><sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 02:47, 9 April 2014 (UTC)
* '''Autofixing is better than save-with-errors:''' Even a language such as Lua should be autofixing simple errors, such as inserting "then" when omitted. With the development of computer-language design using [[LALR(1)]] grammars, the hope of the past 40 years has been to autofix the simple syntax errors and continue operation, when following the grammar [[production rules]] to find the token "then" is the only option to allow valid processing. In the case of an if-statement, it is common to detect an omitted "then" or "end" keyword which, if auto-corrected, would allow the script to continue running, and in fact generate the same results as if it cratered with "Script error" (missing "then"), was hand-fixed, and rerun. The problem arises when a user relies on auto-fixing of all syntax errors, such as always omit "then" in if-statements because they would be autofixed in every case; however, I think reality would be users who insert "then" in most cases, perhaps leaving only a few in the optional warning messages. Otherwise, this error-prone technology of [[fatal error]] messages, "{{red|You didn't say, 'Simon says'.}}" (which craters on every small error) is an unfortunate problem well-solved over 40 years ago. -[[User:Wikid77|Wikid77]] ([[User talk:Wikid77|talk]]) 08:23, 9 April 2014 (UTC)

::autofixing of code is a very bad idea, for the reasons above and if you're autofixing, so you're inserting 'then' statements the editor omits, then it's not valid Lua. Editors should be writing valid Lua. Lua's not hard to learn, a programmer with experience in a similar language can get up to speed with it in an afternoon.

: skew is a rarely used, optional parameter which allows for linear variation in the spacing between latitude or longitude lines.  in my opinion, this feature can be removed entirely, since we can specify arbitrary mappings using the {{para|x}} and {{para|y}}. in fact, I don't know of any actively used maps which are using the skew feature.  the old [[Template:Location map GermanyNeckar]] was using skew, but that was replaced by a more general transformation (e.g., see [//en.wikipedia.org/w/index.php?title=Template%3ALocation_map_CanadaGeo&diff=605392951&oldid=499787169 here]).

== Extracting the name of a map ==

There are some templates, and maybe some articles, which display the name of a map using code such as
:<samp><nowiki>Location within {{Location map {{{pushpin_map}}}|name}}</nowiki></samp>
This code will break for the newer maps that have been implemented as modules instead of templates. I've never used Lua before but I have found, by trial and error, that the fix seems to be to replace the above code by
:<samp><nowiki>Location within {{#invoke:Location map|data|{{{pushpin_map}}}|name}}</nowiki></samp>
This seems to work with both the old templates and the new modules.

I've changed a few templates to fix this:
*{{tlx|Infobox Mandir}}
*{{tlx|Infobox GB bus station}}
*{{tlx|Infobox concentration camp}}
*{{tlx|Infobox temple}}
*{{tlx|Infobox residential college}}

Whilst many maps show regions in outline and nothing more is to be gained from expanding them, many more are city-scale and the location function is being used to locate a point of interest. The thumbnail is of limited use here, it's almost a 'teaser trailer' for a full-screen map. Unfortunately and frustratingly for the end user, the push-pin has now disappeared, making the large map almost useless. 

So here is a challenge: can anyone come up with an algorithm such that the push-pin is carried forward to the expanded map, scaled appropriately.

:There's a way to do it which in theory could be done without rewriting/extending MW. Have the link for each location map link to a special page which is the map at 800 x 600, say, with the push pin. The page would simply contain an invocation of the location map template except at that size, with links to the image's Commons page (in case that's what's needed) and back to the source article.
:* Advantage: do-able with existing software and probably without modifying the template/module

::As I understand it, the purpose of the <samp>name</samp> parameter is to provide a text description of the map location, suitable for appearing in phrases such as "shown within <samp>name</samp>" or "located in <samp>name</samp>". As such, it doesn't need to be the name of an article. For example, I've created maps where the name is "Preston city centre" or "the Borough of Wyre", where we don't have articles with those exact names. If there's a need for a link to an article as well, maybe there should be a separate parameter to achieve that (which would default to <samp>name</samp> if not set)? --<span style="border:1px solid #006000">[[User:Dr Greg|<span style="color:#FFFF80;background:#006000">'''&nbsp;Dr&nbsp;Greg&nbsp;'''</span>]][[User talk:Dr Greg|<span style="color:#006000;background:#FFFF80">&nbsp;<small>talk</small>&nbsp;</span>]]</span> 16:21, 19 October 2014 (UTC)

== Understanding Location map coordinates ==

In [[Akashi Kaikyō Bridge]], {{tlx|Location map}} is coded as the value of {{para|extra}} in {{tlx|Infobox bridge}}. While converting the deprecated {{para|coordinates}} in the infobox, I removed the coordinates values from {{tlx|Location map}} to see if it would obtain the coordinates from the infobox. The map did not change, the marker is still displayed correctly.

First, if the map can obtain the coordinates from the infobox, I'm wondering why the doc doesn't say anything to that effect. 

Further, when I altered the infobox longitude by 30 degrees, the map marker didn't move. 

What's going on here? &#8209;&#8209;[[User:Mandruss|<span style="color:#8E8278;">'''''Mandruss'''''</span>]]&nbsp;[[User talk:Mandruss|<span style="color:#AAA;">&#9742;</span>]] 11:43, 9 November 2014 (UTC)

:{{ping|عبد المؤمن}} To your first question, there's not really a good way to do that right now. The best way is currently [[Template:Location map-line]], but it's extremely limited.

:::{{ping|عبد المؤمن}} You can hide the marker by setting marksize to 0.

'''Link= mouseover does not work?:''' I found a workaround, but there appears to be an error in your code. The article to this talk page says "link" "Specifies a wiki link which will be followed if the reader clicks on the mark. The name of the linked article is displayed when the mouse pointer hovers over the mark." As near as I can tell this only works if {link=X|label=[*[X]*]} (ignore the asterisk). Without this: 1. Clicking the mark will take you to the article, but mouseover will show the label=. 2. If you write link=[*[X]*], mouseover will show the link name, but clicking on the mark takes you to mark=.  Either that or I misunderstand something. Workaround is to write label=[*[ article, bar, label ]*].

I don't know what to do about the code, but I suggest you note the problem in the article. It would save the next person the 6 hours I spent finding a workaround.
(Obviously my fault but some people are dumber than I am.) A quick way might be to patch the USA map with {*{Location map~| USA    | label = [[Kansas City|Mouseover this Label]]| position =bottom| mark=X solid black 17.gif|marksize=15|lat_deg = 39.1| lat_dir = N| lon_deg = 94.6 | lon_dir = W  }*} or whatever might work.

:{{ping|Benjamin Trovato}} The code is working correctly. The documentation was wrong, though I've now fixed it. See if it makes more sense now.

'''This request has not been answered, contrary to box at right.''' [[User:Benjamin Trovato|Benjamin Trovato]] ([[User talk:Benjamin Trovato|talk]]) 20:50, 3 February 2015 (UTC)

Parameters section says: "'''Required'''. Use the name of the map as the first unnamed parameter". As I understand it "name of the map" should be "map template" or whatever it's called.  For example "Russia Dagestan relief locator map.png" requires "Russia Dagestan" in locator map code and "Caucasus topo map-blank.svg" requires "Caucasus mountains". Apparently the way to find these is to double click the map, go down to 'file usage' and find somewhere "Template: Locator map XX" and use the "XX". You sometimes have to use the view button at the bottom to get down far enough to find the template. Is there something that directly associates a map with its template?  I probably misunderstand something, but documentation should prevent misunderstanding where possible.[[User:Benjamin Trovato|Benjamin Trovato]] ([[User talk:Benjamin Trovato|talk]]) 20:27, 3 February 2015 (UTC)
