Help:Displaying Leaflet maps

Source

This is a copy taken on 19 April 2023 of the wiki page Displaying Leaflet maps on maps.extension.wiki.

Contents

Maps supports embedding of dynamic maps using the free and open source Leaflet library.

Basic syntax

Displaying maps is done with the #display_map parser function.

{{#display_map:center=Brandenburg Gate, Berlin, Germany}}

Customization

Leaflet maps can be customized using various parameters.

{{#display_map:center=Berlin|width=400|height=250}}

Displaying data

Markers

{{#display_map:Brandenburg Gate, Berlin, Germany}}

{"minzoom":false,"maxzoom":false,"mappingservice":"leaflet","width":"auto","height":"350px","centre":false,"title":"","label":"","icon":"","lines":[],"polygons":[],"circles":[],"rectangles":[],"copycoords":false,"static":false,"zoom":false,"defzoom":14,"layers":["OpenStreetMap"],"image layers":[],"overlays":[],"resizable":false,"fullscreen":false,"scrollwheelzoom":false,"cluster":false,"clustermaxzoom":20,"clusterzoomonclick":true,"clustermaxradius":80,"clusterspiderfy":true,"geojson":"","clicktarget":"","imageLayers":[],"locations":[{"text":"","title":"","link":"","lat":52.5162699,"lon":13.377703399031432,"icon":""}],"imageoverlays":null}

You can display multiple locations by separating them with semicolons. And it is possible to use coordinates instead of location names.

{{#display_map:Berlin; Brussel; 40° 42' 46.02" N, 74° 0' 21.39" W}}

You can customize the markers per location. The syntax is:

Location~Popup title~Popup text~File:CustomIcon~Group~Inline label~File:VisitedIcon

• Location: the location where to display the marker. Both coordinates and addresses are supported
• Popup title and Popup text: optional content for a popup shown when the marker is clicked. No popup is shown if both are empty
• File:CustomIcon: optional name of an image to display instead of the default marker
• Group:
• Inline label: optional label shown next to the marker. Currently only shown when using Google Maps
• File:VisitedIcon: optional name of an image to display as marker when the marker is clicked

Example:

{{#display_map:
  Berlin~The city Berlin~Berlin is a really nice city and there is plenty of Club Mate~Red-marker.png;
  Amsterdam~The city Amsterdam~Amsterdam is the capital of The Netherlands~Green-marker.png
}}

GeoJSON

As of version 5.6, Maps supports display of GeoJSON via the geojson parameter. See Leaflet GeoJSON files.

Alternative syntax

When you have many customized markers, using the #display_map parser function can get unwieldy. For this reason you can also use the <display_map> tag. It has all the same parameters as the parser function, the only difference is the syntax. Each location goes own its own line and they do not need to be separated with a semicolon.

Example:

<display_map height="150px" scrollwheelzoom="off" service="leaflet">
  Gent, Belgie~The city Ghent~Ghent is awesome~ ~ ~Ghent
  Brussel~The city Brussel~The capital of Belgium~ ~ ~Brussels
  Antwerp~The city Antwerp~ ~ ~ ~Antwerp
</display_map>
