Module:Location map/data/Washington, DC is a location map definition used to overlay markers and labels on an equirectangular projection map of District of Columbia. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.

Usage

These definitions are used by the following templates when invoked with parameter "Washington, DC":

• {{Location map|Washington, DC |...}}
• {{Location map many|Washington, DC |...}}
• {{Location map+|Washington, DC |...}}
• {{Location map~|Washington, DC |...}}

Map definition

• name = District of Columbia

  Name used in the default map caption

• image = District of Columbia Locator Map.PNG

  The default map image, without "Image:" or "File:"

• image1 = District of Columbia relief location map.jpg

  An alternative map image, usually a relief map, which can be displayed via the relief or AlternativeMap parameters

• top = 39.0571

  Latitude at top edge of map, in decimal degrees

• bottom = 38.73

  Latitude at bottom edge of map, in decimal degrees

• left = -77.3637

  Longitude at left edge of map, in decimal degrees

• right = -76.666

  Longitude at right edge of map, in decimal degrees

Alternative map

The {{Location map}}, {{Location map many}}, and {{Location map+}} templates have parameters to specify an alternative map image. The map displayed as image1 can be used with the relief or AlternativeMap parameters. Examples may be found below or in the following:

• Template:Location map#Relief parameter
• Template:Location map+/relief
• Template:Location map#AlternativeMap parameter
• Template:Location map+/AlternativeMap
