Changing map title

Hello, I'm not too skilled in the coding side of wikipedia, so please bear with me! I'm currently trying to change the title of the map Module:Location map/data/China Tibet topography. Right now, it's showing up in the infobox of articles including Mount Everest as China Tibet topography when all it should say is Tibet. Changing the title value in the code didn't seem to change it. Do I have to move the location map module page? Any help is appreciated. --NoGhost (talk) 20:55, 12 March 2017 (UTC)

NoGhost, I searched Mount Everest for "China Tibet topography" and found nothing. What is the problem exactly? Thanks! Plastikspork _―Œ^(talk) 21:26, 12 March 2017 (UTC)

@Plastikspork: Oh, it seems to be displaying correctly now! I guess it just took awhile to update. Thanks for checking. --NoGhost (talk) 21:57, 12 March 2017 (UTC)

Philadelphia map not big enough?

The coordinates for Watson Comly School are outside the Philadelphia box, and I've double checked that the coordinates are correct and are within Philadelphia. The template uses File:Location Map Philadelphia Metropolitan Area.png, which cuts off at or very near the building's location. I can't quite tell from the map styling. Is this an issue with insufficient border coordinates being set, or should there be a larger map for Philadelphia? (Is this even the right place to ask?) kennethaw88 • talk 07:53, 16 March 2017 (UTC)

kennethaw88, if you look at a larger version of the map image, you will see a purple dashed line. that line is the boundary of Philadelphia. it looks like that when User:Vrysxy exported the image from openstreet map, the image was cropped too much. you could try to export a new image from open street map using a larger region. just make sure you keep track of the bounding box lat/long information. or, try asking at WP:Maps or Graphics Lab/Map workshop to see if someone there can help. I would help, but I haven't had any luck with exporting images from openstreetmap. Frietjes (talk) 15:27, 16 March 2017 (UTC)

Thanks, I asked over at WP:Graphics Lab/Map workshop. kennethaw88 • talk 19:01, 18 March 2017 (UTC)

to be used as a map for locations within the city of Pretoria itself. SpringbokSam (talk) 16:40, 23 March 2017 (UTC)

You can do this yourself. Just create the location map data for it, like I did here: Module:Location map/data/Beijing. You only need the precise latitude and longitude of its edges. Or if you have them but are unsure of creating the module post the coordinates here and someone else can easily do it.--JohnBlackburne^words_deeds 17:00, 23 March 2017 (UTC)

Ah, it contains coordinates. I have created the data at Module:Location map/data/Pretoria. To use it simply do {{Location map|Pretoria}} with appropriate coordinates and other parameters. When you do please double-check the location is right, in case the coordinates are not precise enough for the map.--JohnBlackburne^words_deeds 17:07, 23 March 2017 (UTC)

And I made a couple of mistakes but have hopefully now corrected them. I added the map to Transvaal Museum as a test and it seems to be working, and is certainly more useful than a map of the whole province.--JohnBlackburne^words_deeds 17:17, 23 March 2017 (UTC)

Glitch on the Greenwich date line

Location map/Archive 9 (Ghana)

Only one of these maps works; the only difference is using E or W for the longitude. Oddly the coordinates both work fine as standalone coordinates:

Noticed and fixed at Tema. Is likely not going to come up often as there can’t be that many places exactly on the date line, but something odd is happening.--JohnBlackburne^words_deeds 07:01, 6 March 2017 (UTC)

JohnBlackburne, if you inspect the HTML source, you will see that the {{coord}} template is returning 5.66667°N 0.00000°E in the metadata for the first one and 5.66667°N -0.00000°E for the second one. the coord2text code expects the two numbers to be positive. the interesting thing is that there is a second chunk of metadata which has the coordinates with sign separated by a semicolon. I wonder if we should just use that chunk instead of the first chunk. this would help with translating the module to other wikis which have different letter symbols for North/East/South/West. I recently had to do this on the Vietnamese Wiki. Frietjes (talk) 14:15, 6 March 2017 (UTC)

I can see what you mean; Seems to me the problem is with {{coord}}, if it’s outputting plus and minus zero for the same coordinate, especially as there are no negative numbers in the inputs which are valid inputs. But it’s not something I’m confident fixing or proposing a fix as I have no experience with either template, and would be far too wary of breaking anything. This is a particular edge case that’s broken, but fixing it might impact other edge cases.--JohnBlackburne^words_deeds 06:58, 8 March 2017 (UTC)

One more instance of it: Bilanga-Yanga. Fixed, posted for reference.--JohnBlackburne^words_deeds 15:41, 13 March 2017 (UTC)

JohnBlackburne, those poor people who have to live in the middle of a lake! I fixed the imprecise coordinates. thank you! Frietjes (talk) 16:18, 13 March 2017 (UTC)

Ah,.thanks. This one I thought "I’ve seen this before!" and rapidly fixed it checking it only in preview. I did not think to check whether the position made sense.--JohnBlackburne^words_deeds 16:22, 13 March 2017 (UTC)

Maplandia map problem?

And one more: Ganta, Burkina Faso. This was another one which was wrong, though not horribly wrong so it was easy to find and fix. Except oddly I too got it wrong first time as I copied the values from here: Ganta Map — Satellite Images of Ganta which has the minutes as 30'W instead of 3'W, despite locating it correctly on the map. I don’t know if this is a syatemic error with this service, in which case a lot of other locations could be wrong if people are basing them on it.--JohnBlackburne^words_deeds 13:24, 18 March 2017 (UTC)

@JohnBlackburne and Frietjes: Fixed; the issue was that the coord2text regex didn't allow negative numbers. {{coord}} should probably be modified so it outputs 0.0°S/W instead of -0.0°N/E. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 08:46, 23 April 2017 (UTC)

Thanks. I think I’ve encountered it a couple more times since, but was easy to fix, checking the coords for more precise ones, working round it if zero was correct. I do agree, outputting negative zero makes no sense at all; even if output values ranged over positive and negative numbers, zero is not normally considered negative, outside of some fairly esoteric cases in mathematics.--JohnBlackburne^words_deeds 15:13, 23 April 2017 (UTC)

Icon position error

Moved from Template talk:Coord § Icon position error

– Jonesey95 (talk) 14:49, 23 April 2017 (UTC)

I noticed that the position of the airplane icon (the "pushpin_mark" graphic) is misleading in the Joint Base Anacostia–Bolling article. It appears at the tip of Greenleaf Point, even though the coordinates for JBAB appear to be correct in the template. Clicking on the Coordinates text in the article as displayed shows the correct location about a mile south of Greenleaf Point. At first I thought this error was related to the fact that the pushpin label wraps across three lines, but reducing the label to one line doesn't solve the problem. So I don't know how to fix the problem, but it seems to be real enough. 76.22.118.146 (talk) 02:00, 23 April 2017 (UTC)

JB Anacostia–Bolling

See the pushpin map at right. Is the aeroplane icon displayed in the correct position here? If it is, there is some sort of problem in extracting coordinate values from {{Coord|38|50|34|N|077|00|58|W|name=JB Anacostia–Bolling|display=inline,title}} but if it is also wrong, the problem is nothing to do with {{coord}} but concerns {{Location map}}, and is most likely to be the corner coordinates that are recorded at Template:Location map USA District of Columbia. The best place to discuss that is at Module talk:Location map. --Redrose64 🌹 (talk) 08:53, 23 April 2017 (UTC)

JB Anacostia–Bolling

Replacing the map name with "Washington, DC" works for some reason, even though the location map in question appears to be a redirect. I must be looking in the wrong place for the map that is used. I don't know if this helps, but the map corner coordinates used at Module:Location map/data/USA District of Columbia and Template:Location map USA District of Columbia do not match. – Jonesey95 (talk) 14:44, 23 April 2017 (UTC)

@Jonesey95: The template should probably be deleted and its bounding box values moved to the module subpage. (The module subpage also seems to have other problems, like a second image which doesn't exist.) Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 15:02, 23 April 2017 (UTC)

Fixed the module. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 15:09, 23 April 2017 (UTC)

That works for me. Now the two maps match. ~~Why did "Washington, DC" work though? Where is the file or data for that?~~ I see that you also fixed Module:Location map/data/Washington, DC, which was making "Washington, DC" work as a map name.

I fixed a typo in the documentation to make that image appear. – Jonesey95 (talk) 15:17, 23 April 2017 (UTC)

@Jonesey95: I've replaced all the redirects to the template as module subpages as well and CSDed the template. Jc86035 (talk) Use {{re|Jc86035}}
to reply to me 15:40, 23 April 2017 (UTC)

Looks fine now. Thanks to all for your help. 76.22.118.146 (talk) 23:51, 27 April 2017 (UTC)

Selecting maps to show based on coordinates?

I'm trying to incorporate location maps in infoboxes that are entirely using data from Wikidata, such as Template:Infobox telescope. See South Pole Telescope for an example of this in action, where it is working well by using coordinate location (P625) and country (P17). However, in cases like Arecibo Observatory, this does not work so well, since the country is the United States, but File:Usa edcp relief location map.png doesn't include the right part of the US. Even worse is places that are located in Hawaii! I was wondering if there was a way of automatically selecting the map to show based on the coordinate given at all? Alternatively, is there a good matching between the location maps here and a Wikidata property that could be applied here? Thanks. Mike Peel (talk) 22:57, 4 May 2017 (UTC)

For frwiki, we decide to choose to use the coordinates to determine the map. Note that isn't a perfect solution, it always give the United States map for places in southern Ontario or Quebec. --Fralambert (talk) 23:31, 4 May 2017 (UTC)

@Mike Peel: Sooner rather than later we will be able to link to map data on Commons on Wikidata items. I would guess this could be used to select the correct maps. You probably shouldn't use country but instead "is in administrative territory" (though there are a few other possibilities, that one will be the most relevant), which will get you the smallest place in which the 'scope is located. --Izno (talk) 02:44, 5 May 2017 (UTC)

@Izno: What's the barrier with linking map data on Commons to Wikidata items? Can the location map code cope with, e.g., Arecibo (Q640728)? Thanks. Mike Peel (talk) 02:46, 5 May 2017 (UTC)

@Mike Peel: I... don't actually know if I can answer that? Maybe I'm wrong on this point. Maybe drop this question at d:WD:PC for once. --Izno (talk) 02:50, 5 May 2017 (UTC)

@Izno: OK, I've started a discussion at [1]. Thanks. Mike Peel (talk) 03:02, 5 May 2017 (UTC)

Multiple maps without an infobox

Location in Michigan and the United States

Oakland Hills Country Club

Oakland Hills Country Club (the United States)

@Jackmcbarn: not sure if it is just me, but the radio buttons are not in the caption, unless I embed the location map in another container (e.g., 2004 Ryder Cup)? can this be fixed? Frietjes (talk) 13:38, 8 May 2017 (UTC)

@Frietjes: I don't think the radio buttons should be in the image caption, since each image has its own caption. Possibly having them in a container like {{stack}} by default would work. Jc86035 (talk) Use {{re|Jc86035}}

Location map error category

I've been fixing errors in the category Category:Location maps with different longitude and latitude precisions. I have cleaned-up all the errors in articles, and a few in Draft/User space too. The category is now empty except for one item, an archived 7-year-old Module talk page. While not causing any "problems", I'd like to get rid of this just to have an empty category, which I will monitor for new errors. Since archives aren't supposed to be edited, and "fixing" the problem there would obscure point of the discussion, is there some technical solution. Can the module be changed to not cause the error report from a talk page perhaps? MB 01:46, 17 May 2017 (UTC)

I have removed the category from the template output on the talk page.[2] I used Special:ExpandTemplates to see the exact code generated, and used {{Replace}} to replace it with nothing. PrimeHunter (talk) 21:57, 17 May 2017 (UTC)
