Semantic Maps examples

Basic examples

Use of the map format. The default mapping service will be used, in this case Google Maps.

{{
#ask:
[[Category:Locations]]
| ?Has coordinates
| format=map
}}

Use of the map format and settings the map width and height.

{{
#ask:
[[Category:Locations]]
| ?Has coordinates
| format=googlemap 
| width=800
| height=500
}}

Queering additional semantic properties

Query showing all cities located in Germany on a map with their population and surface area as pop-up contents of the markers.

{{#ask: [[Category:City]] [[located in::Germany]] 
| ?coordinates
| ?population 
| ?area#km² = Size in km²
| format=map
}}

Query showing the locations off all Events on this wiki together with a load of information about these events. The query has a limit of 42, meaning at most 42 results will be shown on the map. The format is set to googlemaps, ensuring a Google Maps map, and the map type is set to physical.

{{#ask: [[Category:Events]]
| ?Has coordinates
| ?Has presenter=Presenters
| ?Has start date=Start date
| ?Has end date=End date
| ?Has address=Address
| ?Has city=City
| ?Has country=Country
| ?Has attendee=Attendees
| limit=42
| format=googlemaps
| type=physical
| icon=Green_marker.png
}}

Use of templates

Adding a link to maps.google.com by using a template. See template.

{{#ask: [[Category:City]]
| ?coordinates
| format=map
| template=Google Maps Link
}}

Custom formatting of the queried properties using the template and showtitle parameters. See used template.

{{#ask: [[Category:City]]
| ?coordinates
| ?population 
| ?area#km²
| format=map
| template=City Popup
| showtitle=off
| icon=Blue_marker.png
}}
