This template will generate an error message and garbage if it is transcluded with {{{map}}} undefined. This reduces expansion depth which is critical in many infoboxes that transclude this template.
The parameters {{{label_x}}} and {{{label_y}}} are deprecated. They will remain functional for a time.
This helper template provides a way to display a map in an Infobox. Optionally a location marker can be included.
Usage
Parameter descriptions
Field name
Description
map
The name of the map to be displayed. This is the only required parameter.
map_width
The width of the map image to be displayed. For example map_width=220 and not map_width=220px.
default_width
When this template is used in another template, e.g. an infobox, the default width of the map image preferred by the infobox should be specified here. For example map_width=220. When used with location maps, this value may be modified by a certain value if specified in the location map template. The default value is 220px.
relief
Selects a relief map when assigned any value. This only works when the geographical coordinates method is used and then only for a few maps. See Map display methods.
map_alt
Alt text for the map. A visually impaired reader who uses a screen reader will have access to this text. See WP:ALT.
map_caption
The caption that appears below the map if one is required.
mark
The image file that will be used to mark the location on the map. The default is Red pog.svg. See below.
mark_width
The width of the marker image to be displayed. For example mark_width=8 and not mark_width=8px. The default width is 8px.
label
A text message that will be displayed next to the marker.
label_position
The position of a label with respect to the marker. Valid values are left, right, top, bottom and none.
lat long
Specifies the latitude and longitude of the location when the geographical coordinates method is used. This value must be specified as a signed decimal degree. See below.
x y
Specifies the position of the location marker. The coordinates of the marker in pixels based on a map width of 1000 pixels. The template will scale these values for proper display. See below.
x% y%
Specifies the position of the location marker. x% specifies the percentage of the distance across the image from the left edge and y% specifies the percentage of the distance down from the top edge. See below.
The template {{decdeg}} can be used to allow additional parameters for the entry of geographical coordinates. The template can be used with or without named parameters. If the unnamed option is used all parameters must be supplied but they can be void. The following markup can be used to allow the template user to enter coordinates. These parameters names are recommended by WikiProject Geographical coordinates.
| lat = {{decdeg|{{{lat_d|}}}|{{{lat_m|}}}|{{{lat_s|}}}|{{{lat_NS|}}} }}
| long = {{decdeg|{{{long_d|}}}|{{{long_m|}}}|{{{long_s|}}}|{{{long_EW|}}} }}
To display coordinates in the Infobox two methods can be used. The template {{Infobox coord}} can be used to display coordinates entered using the method discussed above. If the X,Y method is used to display a marker then the template {{coord}} can be used. For examples of coordinate entry see coordinate examples.
