Map of Alaska (click on map to see larger image)

Module:Location map/data/USA Alaska is a location map definition used to overlay markers and labels on an equirectangular projection map of the U.S. state of Alaska. 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 Alaska":

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

Map definition

• name = Alaska

  Name used in the default map caption

• image = USA Alaska location map.svg

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

• image1 = Relief map of USA Alaska.png

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

• top = 72

  Latitude at top edge of map, in decimal degrees

• bottom = 51

  Latitude at bottom edge of map, in decimal degrees

• left = 172

  Longitude at left edge of map, in decimal degrees

• right = -129

  Longitude at right edge of map, in decimal degrees

• x = (100*(($2 + ($2 < 0)*360) - 172)/((-129 + 360) - 172))

  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 = (100*($1 - 72)/(51 - 72))

  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

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

Precision

Longitude: from West to East this map definition covers 59 degrees.

• At an image width of 200 pixels, that is 0.295 degrees per pixel.
• At an image width of 1000 pixels, that is 0.059 degrees per pixel.

Latitude: from North to South this map definition covers 21 degrees.

• At an image height of 200 pixels, that is 0.105 degrees per pixel.
• At an image height of 1000 pixels, that is 0.021 degrees per pixel.
