The Maps extension can aggregate geographical data stored in Semantic MediaWiki onto dynamic and interactive maps such as Google Maps. Each coordinate is shown as a marker on the map, with associated data being displayed when clicking the marker. Coordinate aggregation is done via the Leaflet result format.

Syntax[edit]

The map result format can be used in inline queries and in other semantic queries.

Simple query[edit]

{{#ask: [[Category:City]]
 | format=map
 | ?Has coordinates
}}
Loading map...

For more information on the query syntax, see the SMW inline query documentation.

Distance query[edit]

A distance query for all cities within a 420 km radius of Brussels, using the Distance Popup template:

{{#ask: [[Has location type::City]] [[Has coordinates::50° 50' 48" N, 4° 21' 10" E  (420 km)]]
 | format=map
 | ?Has coordinates
 | ?Located in
 | template=Distance Popup
}}
Loading map...

Compound query[edit]

This example makes use of the Extension "Semantic Compound Queries" extension to pick the used marker per type of location.

{{
 #compound_query:
 [[Category:Locations]]
 <q>
  [[Has location type::City]]
  OR
  [[Has location type::Local place]]
 </q>
 ; ?Has coordinates
 ; ?Located in
 |
 [[Category:Locations]]
 [[Has location type::Country]]
 ; ?Has coordinates
 ; ?Located in
 ; icon=Green marker.png
 |
 [[Category:Locations]]
 [[Has location type::Continent]]
 ; ?Has coordinates
 ; ?Located in
 ; icon=Blue marker.png
 | format=map
 | height=400
}}
Loading map...

Customizing maps[edit]

When using format=map, the default mapping service is used. Use format=leaflet or format=googlemaps to specify which mapping service should be used. See their respective documentation pages for mapping service specific customization options and examples.
