Mapframe maps

• Basic parameters:
  • mapframe – Specify yes or no to show or hide the map, overriding the default. Default: no
  • mapframe-caption – Caption for the map. Default: blank (or if |mapframe-geomask= is set, "Location in geomask's label")
  • mapframe-custom – Use a custom map instead of the automatic mapframe. Specify either a {{maplink}} template, or another template that generates a mapframe map, or an image name. If used, the subsequent mapframe parameters will be ignored. Default: not specified
  • mapframe-id or id or qid – Id (Q-number) of Wikidata item to use. Default: item for current page
  • mapframe-coordinates or mapframe-coord or coordinates or coord – Coordinates to use, instead of any on Wikidata. Use the {{Coord}} template, e.g. |coord={{Coord|12.34|N|56.78|E}}. Default: coordinates from Wikidata
  • mapframe-wikidata – Set to yes to show shape/line features from the wikidata item, if any, when |coord= is set. Default: not specified
• Customise which features are displayed:
  • mapframe-shape – Turn off display of shape feature by setting to none. Use an inverse shape (geomask) instead of a regular shape by setting to inverse. Default: not specified
  • mapframe-point – Turn off display of point feature by setting to none. Force point marker to be displayed by setting to on. Default: not specified
  • mapframe-line – Turn off display of line feature by setting to none. Default: not specified
  • mapframe-geomask – Wikidata item to use as a geomask (everything outside the boundary is shaded darker). Can either be a specific Wikidata item (Q-number), or a property that specifies the item to use (e.g. P17 for country (P17), P131 for located in the administrative territorial entity (P131)). Default: not specified
  • mapframe-switcher – set to auto or geomasks or zooms to enable Template:Switcher-style switching between multiple mapframes. Default: not specified
    • auto – switch geomasks found in location (P276) and located in the administrative territorial entity (P131) statements on the page's Wikidata item, searching recursively. E.g. an item's city, that city's state, and that state's country.
    • geomasks – switch between the geomasks specified as a comma-separated list of Wikidata items (Q-numbers) in the mapframe-geomask parameter
    • zooms – switch between "zoomed in"/"zoomed midway"/"zoomed out", where "zoomed in" is the default zoom (with a minimum of 3), "zoomed out" is 1, and "zoomed midway" is the average
• Other optional parameters:
  • mapframe-frame-width or mapframe-width – Frame width. Default: 270
  • mapframe-frame-height or mapframe-height – Frame height. Default: 200
  • mapframe-shape-fill – Color used to fill shape features. Default: #606060
  • mapframe-shape-fill-opacity – Opacity level of shape fill, a number between 0 and 1. Default: 0.5
  • mapframe-stroke-color or mapframe-stroke-colour – Color of line features, and outlines of shape features. Default: #ff0000
  • mapframe-stroke-width – Width of line features, and outlines of shape features; default is "5". Default: 5
  • mapframe-marker – Marker symbol to use for coordinates; see mw:Help:Extension:Kartographer/Icons for options. Default: not specified (i.e. blank)
    • Can also be set to blank to override any default marker symbol
  • mapframe-marker-color or mapframe-marker-colour – Background color for the marker. Default: #5E74F3
  • mapframe-geomask-stroke-color or mapframe-geomask-stroke-colour – Color of outline of geomask shape. Default: #555555
  • mapframe-geomask-stroke-width – Width of outline of geomask shape. Default: 2
  • mapframe-geomask-fill – Color used to fill outside geomask features. Default: #606060
  • mapframe-geomask-fill-opacity – Opacity level of fill outside geomask features, a number between 0 and 1. Default: 0.5
  • mapframe-zoom – Set the zoom level, from "1" (map of earth) to "18" (maximum zoom in), to be used if the zoom level cannot be determined automatically from object length or area. Default: 10
  • mapframe-length_km or mapframe-length_mi or mapframe-area_km2 or mapframe-area_mi2 – Determine zoom level by passing in object's length (in kilometres or miles) or area (in square kilometres or square miles). Default: not specified
  • mapframe-frame-coordinates or mapframe-frame-coord – Alternate latitude and longitude coordinates for initial placement of map, using {{coord}}. Default: derived from item coordinates

Microformat

The HTML markup produced by this template includes an hCard microformat, which makes the place-name and location parsable by computers, either acting automatically to catalogue articles across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to an address book. Within the hCard is a Geo microformat, which additionally makes the coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map, or downloaded to a GPS unit. For more information about the use of microformats on Wikipedia, please see the microformat project.

Sub-templates

If the place or venue has "established", "founded", "opened" or similar dates, use {{start date}} for the earliest of those dates unless the date is before 1583 CE.

If it has a URL, use {{URL}}.

Please do not remove instances of these sub-templates.

Classes

hCard uses HTML classes including:

• adr
• agent
• category
• county-name
• extended-address
• fn
• label
• locality
• nickname
• note
• org
• region
• street-address
• uid
• url
• vcard

Geo is produced by calling {{coord}}, and uses HTML classes:

• geo
• latitude
• longitude

Please do not rename or remove these classes nor collapse nested elements which use them.

Precision

When giving coordinates, please use an appropriate level of precision. Do not use {{coord}}'s |name= parameter.
