Module:Location map/data/USA is a location map definition used to overlay markers and labels on an equidistant conic projection map of the United States. 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 "USA":

• {{Location map|USA |...}}
• {{Location map many|USA |...}}
• {{Location map+|USA |...}}
• {{Location map~|USA |...}}

Map definition

• name =

  Name used in the default map caption

• image = [[:File:|]]

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

• image1 = [[:File:|]]

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

• image2 = [[:File:|]]
• image3 = [[:File:|]]
• image4 = [[:File:|]]

  Alternative map images which can be displayed via the AlternativeMap parameter

• top =

  Latitude at top edge of map, in decimal degrees

• bottom =

  Latitude at bottom edge of map, in decimal degrees

• left =

  Longitude at left edge of map, in decimal degrees

• right =

  Longitude at right edge of map, in decimal degrees

• x =

  An expression to calculate a location on the map via its longitude; evaluates as 0 along the left edge and 100 along the right edge

• y =

  An expression to calculate a location on the map via its latitude; evaluates as 0 along the top edge and 100 along the bottom edge

• mark = [[:File:|]] ([[File:||8px]])

  The default mark image to display with this map. This can be overridden by the mark parameter in Template:Location map, which would otherwise default to Red pog.svg ().

• marksize =

  The default mark size (in pixels) for the mark image displayed with this map (should not include px, for example marksize=, not marksize=px). This can be overridden by the marksize parameter in Template:Location map, which would otherwise default to 8.

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. The maps displayed as image2 / image3 / image4 can be used with the AlternativeMap parameter. 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

Precision

Longitude: from West to East this map definition covers degrees.

• At an image width of 200 pixels, that is degrees per pixel.
• At an image width of 1000 pixels, that is degrees per pixel.

Latitude: from North to South this map definition covers degrees.

• At an image height of 200 pixels, that is degrees per pixel.
• At an image height of 1000 pixels, that is degrees per pixel.

Examples using location map templates

Location map, using default map (image)

{{Location map | USA
| width   = 250
| label   = Washington, D.C.
| lat_deg = 38.89
| lon_deg = -77.04
}}

Location map many, using relief map (image1)

{{Location map many | USA
| relief   = yes
| width    = 250
| caption  = Two locations in the United States
| label1   = Washington, D.C.
| lat1_deg = 38.89
| lon1_deg = -77.04
| label2   = Seattle
| lat2_deg = 47.61
| lon2_deg = -122.33
}}

Location map+, using AlternativeMap

{{Location map+ | USA
| AlternativeMap = Usa edcp relief location map.png
| caption = Two locations in the United States
| width   = 250
| places  =
  {{Location map~ | USA
  | label   = Washington, D.C.
  | lat_deg = 38.89
  | lon_deg = -77.04
  }}
  {{Location map~ | USA
  | label   = Seattle
  | lat_deg = 47.61
  | lon_deg = -122.33
  }}
}}

Location map, one location on three maps

{{Location map | USA#USA Tennessee#North America
| relief  = yes
| width   = 250
| lat_deg = 36.167
| lon_deg = -86.783
| label   = Nashville
}}

Location map, three maps and three captions

{{Location map | USA#USA Tennessee#North America
| relief  = yes
| width   = 250
| lat_deg = 36.167
| lon_deg = -86.783
| label   = Nashville
| caption = Location in the [[United States]]##Location in [[Tennessee]]##Location in [[North America]]
}}
