Loßlähje
 This code will insert a simple interactive map (like what you see on the right), with the ability to maximize it by either double-clicking the map or clicking the icon in the right corner.

The  parameter overrides the default alignment to left, right, or center. The attribute  allows for zoom levels between 0 and 19. Zero is the furthest out, 19 the furthest in.

 { "type": "Feature", "geometry": { "type": "Point", "coordinates": [-122.3988, 37.8013] }, "properties": { "title": "Exploratorium", "description": "", "marker-symbol": "museum", "marker-size": "large", "marker-color": "0050d0" } }

The content of the tag has to be either empty or a valid GeoJSON with styling, as produced by a GeoJSON editor. Kartographer supports the simplestyle specification with Maki icons (Licensed under Creative Commons Zero). Maps/Icons contains a full list of supported icons.

Frames
Frameless maps are good for insertion as part of a template, whereas framed maps are good for insertion directly into the page, either by hand or by using the visual editor.


 * To insert a map without a frame, add the "frameless" attribute:
 * To add a caption, use the  attribute.

Note: Adding the text attribute automatically enables a frame, even if there is a  attribute.

==

also accepts an extra parameter "text" to specify link text instead of the coordinates:

The tag may contain the same geojson as.

=== attribute. Without this attribute, the coordinates will be shown (example:  is set to the magic   or   value. In this case each   will be replaced with an incremental counter , and   with   values.

If GeoJSON has more than one counter, the value of the first one will be shown as the link text. Optionally, editors may add a suffix to have multiple counters on the page at the same time. This way  will have different counter from.

It would make sense to use a distinct color for each counting group. All data added via will also be shown in all maps inserted with, unless the   attribute is used.

The attributes,  , and   control the location of the popup map. Use  for the text of the link (could be any valid wikitext markup). Use  to add the contents of this tag to the named group (see below).

Markers
Markers can be added to maps to denote a location. These features are added using the JSON format.

Note: These examples use, but the formatting for   is the same.

Result:

Markers can also contain information such as images and links to articles.

Result (interact with marker to see result):

Wikidata IDs for OSM data can be used to highlight borders using the geoshape service.

Result:

Wikidata IDs can be used to mask the entire map except a specified region.

Result:

Markers can be numbered.

Result:

Markers can use letters.

Result:

Add several map markers in different sizes using a feature collection.

Result:

Add groups of different colored map markers and different counters.

Result:


 * Map markers can use any color that has a RBG value (a quick internet search of "rgb color picker" will show several options).
 * Markers can be one of three different sizes: small, medium or large.
 * GeoJSON that is created elsewhere can be copied (in accordance with licensing and copyright restrictions) and then pasted into maplink (for example)
 * If you are creating maps on Wikivoyage, it might be a good idea to use Groups (see below).
 * If you want to learn more about adding external data to your map, see the External data section.

Jroppe
For use on the Wikivoyage project, there is a need to show a map whose data is defined somewhere else on the page. For example, there may be multiple points of interest (POI) defined with tags, and one common map on the side of the page that shows them all.

The grouping concept allows editors to share data between multiple and  tags.

By default, the data inside the or  tag is shown only for that one tag, and will not be shown anywhere else.

If or  specify the   attribute, the data inside those tags will be placed into a named group, together with all the other data by the same group name. As a result, any tags with the same group name will show the same map data, and each tag may incrementally add data to the group.

Ene Befähl kann och annder Jroppe aanzeije, ejahl, ov_er en en Jropp es uddder nit, endämm mer en Eijeschavv aanjitt. Comma-separated multiple group names may be specified. The group name may only contain lower case English letters. Heh di Tabäll zeijsch wat för en Dahte för jehe Befähl aanjezeijsch wähde.

External data
 { "type": "ExternalData", "service": "geoshape", "ids": "Q797" }

In addition to drawing polygons using GeoJSON, you may also get outlines of the well known geographical objects by their Wikidata ID if they are marked as such in the OpenStreetMap database. For example, the Wikidata item for Alaska is Q797, and we can draw it on a map by using the "external data" reference. More than one ID may be specified separated by a comma. To create a mask over the areas of interest, use the "geoshape" service. To invert this and create a mask over everything else, use the "geomask" service.

GeoShapes via Wikidata Query
 { "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(, ?headLabel, ) as ?title)  (concat(?stateLabel, '\\n', '') as ?description) WHERE {    ?id wdt:P31 wd:Q35657 .  ?id wdt:P6 ?head .  ?head wdt:P102 ?party .  BIND(if(?party = wd:Q29468, '0', if(?party = wd:Q29552, '1', '2')) as ?partyId)   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  . } GROUP BY ?id ?head ?headLabel ?link ?stateLabel "}

While this helps with the simple use cases when the Wikidata ID is well known, sometimes you may want to get a list of IDs as a result of a Wikidata query. A SPARQL query gets a list of all US states in the ID column of the result, and geoshapes service adds the geometrical outlines for each state. All other columns in the SPARQL query result become values in the "properties" object. The "fill" column changes the color of the state. The "title" column shows state governor's name, and "description" has wiki markup to show the state name and the governor's picture. To edit this query, copy the query parameter after the "#" symbol at ''' https://query.wikidata.org/#... ''':

Map data from Commons

 * Further information: 

Map data stored on Commons can be drawn on the map. For example, c:Data:Neighbourhoods/New York City.map:  { "type": "ExternalData", "service": "page", "title": "Neighbourhoods/New York City.map" }

Combining multiple data types
 [ {    "type": "ExternalData", "service": "geoshape", "ids": "Q13518258", "properties": { "stroke": "#ffb100", "stroke-width": 6, } },  {    "type": "Feature", "geometry": { "type": "Point", "coordinates": [4.75566, 44.104498] }, "properties": { "title": "Porte de Castellan" } },  {    "type": "Feature", "geometry": { "type": "Point", "coordinates": [4.75829, 44.10258] }, "properties": { "title": "Porte Léon Roche" } } ]

You can combine ExternalData, Feature, and FeatureCollection together in the same &lt;mapframe> or &lt;maplink> element:

 [ {    "type": "ExternalData", "service": "page", "title": "Neighbourhoods/New York City.map" }, {    "type": "ExternalData", "service": "geoshape", "ids": "Q160409", "properties": { "fill": "#07c63e", "title": "Central Park" } },  {    "type": "Feature", "properties": {"title": "Roosevelt Island", "marker-color": "f01080"}, "geometry": { "type": "Point", "coordinates": [ -73.94511222839355,       40.76734665426719      ]    }  } ]

Map data from Commons can be combined with other types of data:

Styling Wikidata ID elements
 { "type": "ExternalData", "service": "geoline", "ids": "Q2108", "properties": { "title": "Highway I-696", "description": "", "stroke": "#ffb100", "stroke-width": 8 } }

For external data, you can also add styles and titles, using the properties keyword:

The main style keys are: "stroke" (color), "stroke-width", "stroke-opacity", "fill" (color), "fill-opacity".

Overlapping elements
Map elements that overlap are drawn in the order in which they are written in the code. For instance, if a map includes two lines that overlap, the line that is defined first will appear beneath the line that is defined second. The following examples show how this can affect the appearance of the map:

 { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {"fill": "#ff0000","fill-opacity": 0.7,"stroke-width": 0}, "geometry": { "type": "Polygon", "coordinates": [ [ [ 77.926025390625, -25.150257104114733 ], [ 80.14251708984374, -25.150257104114733 ], [ 80.14251708984374, -24.43714786161562 ], [ 77.926025390625, -24.43714786161562 ], [ 77.926025390625, -25.150257104114733 ] ] ] } }, { "type": "Feature", "properties": {"stroke": "#fffa00","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -25.150257104114733 ], [ 80.14251708984374, -24.43714786161562 ] ] } }, { "type": "Feature", "properties": {"stroke": "#000000","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -24.43714786161562 ], [ 80.14251708984374, -25.150257104114733 ] ] } } ] }

The code for the map above includes three elements, all of which use GeoJSON's "feature" functionality. The first feature is a "Polygon" - the red rectangle. This is followed by two "LineString" features. The yellow line is defined first, so it appears beneath the black line. Note that the hierarchy used to draw elements applies regardless of whether the data is raw GeoJSON or comes from a Wikidata ID or Commons data page.

The map below changes the order from that of the first example: the black line is defined first and is thus moved to the bottom of the stack:  { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {"stroke": "#000000","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -24.43714786161562 ], [ 80.14251708984374, -25.150257104114733 ] ] } }, { "type": "Feature", "properties": {"fill": "#ff0000","fill-opacity": 0.7,"stroke-width": 0}, "geometry": { "type": "Polygon", "coordinates": [ [ [  77.926025390625,  -25.150257104114733  ],  [  80.14251708984374,  -25.150257104114733  ],  [  80.14251708984374,  -24.43714786161562  ],  [  77.926025390625,  -24.43714786161562  ],  [  77.926025390625,  -25.150257104114733  ]  ]  ]  } }, { "type": "Feature", "properties": {"stroke": "#fffa00","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -25.150257104114733 ], [ 80.14251708984374, -24.43714786161562 ] ] } } ] }

Rendering options
The following table shows how a map can be formatted for display on a wiki page. The table contains two columns: the first shows an interactive map via the tag, and the second showing the rendering of an example image with the same options.

Map languages
As of May, 2018, map labels will try to use the language of the wiki where the embedded map is displayed. If that language is not available, then the map will use the languages configured as fallback(s) in MediaWiki for that language. If the label is not available in a fallback language, then English is used. Finally, if no language is available, then the map will display labels in the language of the territory mapped.

You can specify the language to use for labels by adding the  followed by the desired language code. e.g. lang="ja" to display labels in Japanese (if available).

Result:. This shows map labels in the languages of the area mapped (essentially opting out of internationalization).

Maps use map data, including map label data for all languages, from the open-source mapping project OpenStreetMap. If the map you want to display doesn’t offer labels in the desired language, you can add labels in that language by adding them to OpenStreetMap. To get you started, there is an OpenStreetMap Beginners’ Guide, and guidance about naming conventions.
