Template:Maplink

Maplink

Template documentation[view] [edit] [history] [purge]

This template adds a link, or frame, which will display a map from OpenStreetMap together with specified map data. The map and data can be viewed in a scrollable and zoomable fullscreen window. The map data can come from:

• data stored in GeoJSON format on Wikipedia or Commons
• line/polygon features in OpenStreetMap.
• coordinates, either supplied or from Wikidata
• raw GeoJSON, preferably transcluded from another page

Note:

• If you have a very large/slow map, you should use the mapframe extension tag directly instead of this template, as was done in Special:Diff/970846012. The reason for this is that using the template to call the extension tag will result in the map rendering counting as Lua time, which may result in time exceeded errors.
• GeoJSON files cannot currently be directly uploaded. Instead, on Commons, create a page that is in the Data: namespace and ends in .map – see mw:Help:Map Data for further information.
• To make OpenStreetMap (OSM) features available, add the Wikidata key to the OSM relation (and wait 1 or 2 days) – see mw:Help:Extension:Kartographer#External_data, mw:Help:Extension:Kartographer/OSM and Module talk:mapframe/FAQ for further information.

Uses

This template is intended to show points as well as linear or polygon features on a map, including (but not limited to):

• Roads
• Rivers
• Subway or train lines
• Ship courses
• Flight paths
• Explorers journeys
• Animal habitats
• Countries and their subdivisions

and more... This template can also be used to display point features on a map, i.e. coordinates.

Usage

Basic usage

• Data page on Commons (e.g. Data:ecos.fws.gov/Endangered habitat 58938/Plethodon neomexicanus.map):

  {{maplink|from=}} (specify .map data page in from=, excluding Data prefix)

• Raw GeoJSON data (e.g. {{Wikipedia:Map data/Main Roads Western Australia/Forrest Highway}}):

  {{maplink|raw=}} (specify raw GeoJSON, preferably transcluded from a subpage of Wikipedia:Map data)

• Line of a border or a linear feature from OSM:

  {{maplink|type=line|id=}} (Wikidata id only required if another article's Wikidata page is to be used)

• Shape from OSM:

  {{maplink|type=shape|id=}} (Wikidata id only required if another article's Wikidata page is to be used)

• Inverted shape from OSM:

  {{maplink|type=shape-inverse|id=}} (Wikidata id only required if another article's Wikidata page is to be used)

• Point feature (coordinates):

  ...from Wikidata:
  {{maplink|type=point|id=}} (Wikidata id only required if another article's Wikidata page is to be used)

  ...from specified coordinates:
  {{maplink|type=point|coord=}} (specify coordinates using {{Coord}} template)

• All named coordinates from a page or section ({{coord}} templates using the |name= parameter)

  ...from the current page: {{maplink|type=named}} or {{maplink|type=named|from=#Section}}

  ...from another page: {{maplink|type=named|from=Other page}} or {{maplink|type=named|from=Other page#Section}}

• Circle (centred on a point's coordinates):

  ...from Wikidata:
  {{maplink|type=circle|radius=|id=}} (Wikidata id only required if another article's Wikidata page is to be used)

  ...from specified coordinates:
  {{maplink|type=circle|radius=|coord=}} (specify coordinates using {{Coord}} template)

• To show in a frame, add the parameter |frame=yes: {{maplink|frame=yes|frame-align=left|type=line|id=Q1094308|text=Mapframe example}}.
  

• Additional parameters are available to customise the displayed map, such as |plain=yes to remove the outer frame: {{maplink|frame=yes|frame-align=left|plain=yes|type=line|id={{get QID|Várkerület}}|frame-width=200|frame-height=250|frame-long=19.1009|frame-lat=47.5001|zoom=9}}.
  

• Overlays can also be displayed on top of the map: {{maplink|frame=yes|frame-align=left|frame-width=400|frame-height=300|type=point|id=Q8688|marker=airport|zoom=12 |text=San Francisco International Airport |overlay={{Graph:Street map with marks|width=110|height=90|lat=37.8|lon=-121.8|zoom=6|{ "lat": 37.618, "lon": -122.375 }| minimap=false}}}}

title - Only displays the title link

inline,title - Displays the inline link as well as the title link

title,inline - Same as above

text

Text to display for the link (or caption if using mapframe); default is "Map"

icon

Set to "no" to turn off the icon that appears next to the link

zoom

Zoom level, from 1 to 19 (larger numbers zoom in further); default is automatically determined by the map, unless the only feature is a single point.

Mapframe parameters (only work with inline display)

frame

Set to "yes" to show a map frame instead of a link

plain

Set to "yes" to show just the map without the surrounding frame, and without a caption (text parameter will be ignored)

frame-align

Alignment with respect to the page: left, center, or right; default is right

frame-width

Width of the map frame in pixels, default is 300

frame-height

Height of the map frame in pixels, default is 200

frame-coordinates

(or frame-coord)

Optional - coordinates of the center of the map. Use {{Coord}} template to specify coordinates (e.g. |frame-coordinates={{Coord|12.34|S|56.78|W}}). If not set, coordinates will be retrieved from Wikidata.

frame-latitude

(or frame-lat)

(ignored if |frame-coordinates= or |frame-coord= is set)

Optional - latitude coordinate for center of the map.

frame-longitude

(or frame-long)

(ignored if |frame-coordinates= or |frame-coord= is set)

Optional - longitude coordinate for center of the map.

 Note: If frame latitude and longitude are not set by parameters, then frame coordinates can be determined automatically, either:

• Based on the line and shape objects (if any have been specified), or
• From the point feature specified in |coord= (if set), or
• Retrieved from Wikidata (if available – for either the item specified in |id= parameter, or for the page the template is placed on)

overlay

An image, or another map, to be displayed on top the map. E.g.

|overlay=[[File:Example.svg|140x140px]] or

|overlay={{maplink|frame=yes|plain=yes|frame-width=100|frame-height=100|type=shape|id={{get QID|French submarine Ariane (1914)}}|frame-align=center}} or

|overlay={{Graph:Street map with marks|width=100|height=100|lat=37.8|lon=-122.4|zoom=6|{ "lat": 37.8, "lon": -122.4 }|minimap=false}}

(see Template:Maplink/testcases/overlays to view examples)

overlay-border

CSS style for the border, e.g. 3px solid black; default is 1px solid white. The colour can be any web color name or hex code.

Raw GeoJSON

raw

Raw GeoJSON (preferably transcluded from a subpage of Wikipedia:Map data) as well as <maplink> functionality not available via the other parameters. See below for more information.

For each feature

Multiple features can be displayed on a single map. For each additional feature, add a sequential number to the end of the parameter name. For example, the second uses parameters like |type2=, |id2=, etc., the third feature |type3=, |id3=, etc., and so on. Higher numbers are drawn on top.

type

Type of data. Valid values are:

line – a geoline feature from OSM (e.g. a road)

shape – a geoshape feature from OSM (e.g. a state or province)

shape-inverse – a geomask feature from OSM (the inverse of a geoshape - allows an unobstructed view of the map beneath)

data – a geoJSON data page on Commons (parameter is optional in this case)

point – a point feature (coordinates)

named – all named coordinates in an page or section ({{coord}} templates with |name= parameter)

circle – a circle centred on a point's coordinates

id

(or ids)

Wikidata id (Q-number) of the point feature, Wikidata id that the OSM line/shape feature is tagged with. Separate multiple ids with a comma. Defaults to the current page's Wikidata id (if |from= not set).

from

Source of map data:

• If type is data or omitted: The JSON (.map) file from Commons to display (excluding the Data: prefix)
• If type is named: Page name, or name#section, to get named coordinates from. If omitted, or specified as just #section, then current page will be used.

title

Title of the feature (for features from OSM), displayed when the feature is clicked on; default is the page title

description

Description of the feature (for features from OSM), displayed when the feature is clicked on; optional

stroke-color

(or stroke-colour)

Color code for the color used to draw the feature (for features from OSM); default is #ff0000 (red)

stroke-width

Width for the lines used to draw the feature (for features from OSM); default is 6

stroke-opacity

Opacity for the lines used to draw the feature (for features from OSM) – a number between 0 (fully transparent) and 1 (fully opaque); default is 1

fill

Color code for the fill color of the feature (for shape or shape-inverse features from OSM); default is #000000 (black). Note that a semi-transparent version of the specified color will be used by default, allowing the map below to still be seen.

fill-opacity

Opacity for the fill color of the feature (for shape or shape-inverse features from OSM) – a number between 0 (fully transparent) and 1 (fully opaque); default is 0.5

coord

Coordinates to display for a point feature. Use {{Coord}} template to specify coordinates (e.g. |coord={{Coord|12.34|S|56.78|W}}). If not set, coordinates will be retrieved from Wikidata.

marker

Name of Maki marker image to display at the point feature. See mw:Maps/Icons for options. If not set, a plain marker will be shown without an image.

marker-color

(or marker-colour)

Color code (Hex triplet) specifying marker background color. Default is 5E74F3 ( )

marker-size

Size of the marker. Can be small, medium (default) or large.

radius

(or radius_m), or alternative parameters radius_km, or radius_mi, or radius_ft

Radius of the circle. In metres by default, or in kilometers or miles or feet if the alternative parameters are used.

edges

Number of edges used to construct the circle. Default is 32. Higher numbers will result in a smoother circle but use more Lua processing resources.

TemplateData

Adds a link, or frame, which will display map data

Template parameters[Edit template data]

Parameter		Description	Type	Status
display	display	How the template is displayed Suggested values inline title inline,title Default inline	Unknown	optional
text	text	Text to display for the link (or caption if using mapframe) Default Map	Line	optional
icon	icon	Set to "no" to turn off the icon that appears next to the link	Boolean	optional
zoom	zoom	Zoom level, from 1 to 19 (larger numbers zoom in further); default is automatically determined by the map, unless the only feature is a single point.	Number	optional

Multiple map switcher

An option for Template:Switcher-style switching of multiple mapframes, where specified parameters like zoom, or frame coordinates, or a shape's item id are switched between different values. When using, ensure the number of values in each list are the same.

Instructions:

1. Add parameter switch to specify labels for the different options: a list separated by either,, or ; if the labels contain commas, or ### if the labels contain semi-colons. Each label will be displayed with a prefix of "Show ".

   Example: |switch=zoomed out, zoomed mid, zoomed in

2. For each parameter that is to be switched, set its value to SWITCH: followed by a list of values to switch between, again separated by , or ; or ###

   Example: |zoom=SWITCH:4,9,14

   Parameters frame, plain, and text should not be switched

3. Make sure each list has the same number of entries. The position of value in a SWITCH: list corresponds to the same position in the list of labels set in |switch=.

Example:

{{mapframe|frame=yes|type=point|id=Q100|text=Boston|zoom=SWITCH:4,9,14|switch=zoomed out, zoomed mid, zoomed in}}

Examples and tips

Multiple features

Multiple features allow you to:

• Use external data from both Wikimedia Commons and OpenStreetMap together
• Apply different styles to different external data features from OpenStreetMap
• Include multiple links to external data from Wikimedia Commons

{{Maplink|frame=yes
|type=shape|id=Q3495894|title=Shape|description=Description of shape
|type2=line|id2=Q1318331|title2=Line|description2=Description of line
|type3=point|coord3={{coord|32|S|116|E}}|title3=Point|description3=Description of point
}}

{{Maplink|frame=yes|plain=yes|frame-width=250|frame-height=280|zoom=6|frame-lat=29.185|frame-long=76.225
|type=shape-inverse|id=Q1174|title=Haryana
|type2=point|id2=Q200663|stroke-width=3|title2=Faridabad
}}

Infoboxes

Mapframes can be included in infoboxes. Using |plain=yes to remove the outer frame is recommended.

For simple cases with a single feature, {{infobox mapframe}} can be used instead (see that template's documentation for details).

Mitchell Freeway
Map of Perth's northern suburbs with Mitchell Freeway highlighted in red
Type	Freeway

{{Infobox Australian road
| location = {{maplink |type=line |frame=yes |plain=yes |frame-align=center |frame-lat=-31.8262 |frame-long=115.7877 |zoom=9}}
  ...  (other parameters omitted)  ...
}}

The raw parameter

The "raw" parameter allows the same inputs as the full <maplink> function. It allows you to:

• Use GeoJSON data directly
• Use Wikidata queries to obtain information for the map
• Use templates - if a map includes direct GeoJSON or many components, placing the data in a template will avoid cluttering the article text

See mw:Help:Extension:Kartographer for instructions.

Gotchas

• When retrieving lines or shapes from OSM, you can't style the fill color or the opacity level of fills or strokes (unless you use the |raw= parameter)
• The following code utilising the |raw= parameter won't work because the curly brace to close the GeoJSON is adjacent to the curly braces to close the template:

{{Maplink|raw= {"type": "ExternalData","service": "geoshape","ids": "Q13518258"}}}

To fix it, put a space before the two template braces or move them to a separate line.

FAQ

Q1: Where to file a bug report when there is a problem with the base map? (e.g. a missing lake)

A1: If the problem also occurs on OpenStreetMap, it needs to be fixed there. If the problem is only on Wikimedia's maps, it can be reported on Phabricator (you can log in with you Wikipedia account). See mw:How to report a bug for instructions (for the tags, use Maps). (Alternatively, you can try mw:Help talk:Extension:Kartographer)

Q2: Where to report other bugs or problems with the maps?

A2: This may be a problem with the Wikipedia module, or it may be an underlying software bug (there are lots of those).

• If the problem also occurs when using plain <mapframe>...</mapframe> tags, then it should be reported on Phabricator (you can log in with you Wikipedia account). See mw:How to report a bug for instructions (for the tags, use Maps). (Alternatively, you can try mw:Help talk:Extension:Kartographer)
• If the problem only occurs with Wikipedia's template/module, or you're not sure, report it here. (Alternatively, you can try Wikipedia:Village pump (technical))

Q3: Why does the thumbnail map render as a static image when viewing pages, but is interactive when editing pages?

A3: On Wikipedia, and most wikis other than Wikivoyage, the emdeded thumbnail is a static map, and the full screen map needs to be opened before the map can be zoomed or panned. This is for for performance reasons, and to present some content if javascript is disabled, and for printing.
That preview mode shows an interactive map is a bug, phab:T203863 (and also a performance issue). Further explanation can be found in the comments on phab:T202793.

Q4: Why is a line or shape feature from OpenStreetMap not being shown?

A4: There are several possible causes:

• The feature on OSM needs to be tagged with the Wikidata id, per mw:Help:Extension:Kartographer/OSM. It is not enough to just set OpenStreetMap relation ID (P402) on the Wikidata item.
• Only certain OSM relations (those with type=multipolygon, type=route, type=waterway and type=boundary) can be used, and not others like buildings and public transport master routes. See mw:Help:Extension:Kartographer/OSM#Limitation and phab:T156433.
• It can take 1 or 2 days after tagging on OSM before the data is available here.
• Wikimedia occasionally has problems replicating OSM data (e.g. phab:T218097), or intentionally disables replication due to other problems (e.g. phab:T243609)

Q5: Why are line, shape, or point features are not shown after editing or adding a map, even though they were shown in the page preview?

A5: This is a bug related to generating thumbnail map images. It should fix itself in an hour or two. See phab:T269984 for details.

Q6: A page using mapframe's |raw= parameter is showing error messages of "The time allocated for running scripts has expired." What can be done?

A6: If the amount of raw data to be processed is too large, that timeout message may be shown. You can try moving the raw data to Commons (example) or replacing the mapframe template with the equivalent wikitext using Special:ExpandTemplates (example)
