Module:Football map

Overview
This module is used with the template {{football map}} to simplify creation of maps with the <mapframe> tag provided by the Kartographer extension.
The template takes the same parameters as <mapframe> and adds a number of markers using a series of |stadiumN parameters that are used to general the JSON data for the markers. The stadium data is either taken from an internal list or using Wikidata for the coordinates.
Examples:
- Template:Football map/demo — stadia of London football clubs (using data from module list)
- Template:Football map/demo2— stadia for the Russia World Cup in 2018 (using data supplied in template)
- Template:Football map/demo3 — a selection of English stadia (using a mixture of all three data sources)
- Template:Football map/demo4 — a map of the stadia in List of football stadiums in England (using Wikidata for data parameters)
- Template:Football map/demo5 — a list of clubs and their stadium for the 2018-19 Premier League season (using Wikidata for data parameters)
- User:Jts1882/maps/stadiums — a user test page with some mapframe related information and some more examples
