Template:Maplink

Maplink

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

This template adds a link, or frame, which will display map data – either from:

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

Note:

• 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 and mw:Help:Extension:Kartographer/OSM for further information.

Uses

This template is intended for linear or polygon features, including (but not limited to):

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

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)

• <maplink>: Couldn't parse JSON: Syntax error
  (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)

• To show in a frame, add the parameter |frame=yes.

• Additional parameters are available to customise the displayed map.

Parameters

For overall display

display

How the template is displayed. Valid values are:

inline - Only displays the inline link (you can forego this, as it is the default)

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
(Note that automatically determined zoom level does not work for mapframe maps except when previewing the page – see phab:T193455)

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, default is 300

frame-height

Height of the map frame, default is 200

frame-coordinates

(or frame-coord)

Optional - alternate coordinates for initial placement of 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 - alternate latitude coordinate for initial placement of map.

frame-longitude

(or frame-long)

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

Optional - alternate longitude coordinate for initial placement of map.

If frame latitude and longitude are not set by parameters, then frame coordinates can be determined automatically: either from the point feature specified in |coord= (if set), or coordinates will be retrieved from Wikidata (if available – for either the item specified in |id= parameter, or for the page the template is placed on)

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.

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)

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

The JSON (.map) file from Commons to display (excluding the Data: prefix)

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

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, allowing the map below to still be seen.

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 (    )

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.

Raw GeoJSON example

<maplink>: Couldn't parse JSON: Syntax error

{{maplink|raw={{Wikipedia:Map data/Main Roads Western Australia/Forrest Highway}}|text=Route map}}

(Link to GeoJSON data subpage: Wikipedia:Map data/Main Roads Western Australia/Forrest Highway)

Raw Wikidata query example

{{maplink|frame=yes|raw={
  "type": "ExternalData",
  "service": "geoshape",
  "query": "
SELECT ?id ?head
  (SAMPLE(?img) as ?img) 
  (min(?partyId) as ?party) 
  (if(?party = '0', '#800000', if(?party = '1', '#000080', '#008000')) as ?fill)
  (concat('[[', substr(str(?link),31,500),  '{{!}}', ?headLabel, ']]') as ?title)
  (concat(?stateLabel, '\\n', '[[File:', substr(str(?img), 52, 500), '{{!}}200px]]') as ?description)
WHERE {  
  ?id wdt:P31 wd:Q35657 .

  SERVICE wikibase:label {
    bd:serviceParam wikibase:language 'en' .
    ?head rdfs:label ?headLabel .
    ?id rdfs:label ?stateLabel .
  }
  OPTIONAL {
    ?head wdt:P18 ?img .
  }
  ?link schema:about ?head .
  ?link schema:isPartOf <https://en.wikipedia.org/> .
} GROUP BY ?id ?head ?headLabel ?link ?stateLabel
"}|frame-width=600|frame-height=400|frame-lat=52|frame-long=-110|zoom=3}}

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.

Redirects
