Maps adds a Google Maps result format as part of its integration with Semantic MediaWiki. This result format can be used to visualize queried data onto a map.

Syntax[edit | edit source]

Maps shown with the Google Maps result format can be customized using various parameters. This example demonstrates a query for coordinates stored on page Example data:Berlin coordinates and usage of the kml parameter:

{{#ask: [[Coordinates::+]] [[Example data:Berlin coordinates]]
 | format=googlemaps
 | kml=BerlinDistricts.kml
 | ?Coordinates
 | zoom=9
}}
Result
