Usage

These definitions are used by the following templates when invoked with parameter "USA2":

{{Location map|USA2 |...}}
{{Location map+|USA2 |...}}
{{Location map~|USA2 |...}}

Map definition

name = United States
Name used in the default map caption

image = Usa edcp location map.svg
The default map image, without "Image:" or "File:"

image1 = Usa edcp relief location map.png
An alternative map image, usually a relief map, can be displayed via the relief or AlternativeMap parameters

x = 50.0 + 124.03149777329222 * ((1.9694462586094064-({{{2}}}* pi / 180)) * sin(0.6010514667026994 * ({{{3}}} + 96) * pi / 180))
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 = 50.0 + 1.6155950752393982 * 124.03149777329222 * ( 0.02613325650382181 - (1.3236744353715044 - (1.9694462586094064 - ({{{2}}} * pi / 180)) * cos(0.6010514667026994 * ({{{3}}} + 96) * pi / 180)))
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 map defined as image1 (Usa edcp relief location map.png) can be displayed by using the relief or AlternativeMap parameters in {{Location map}} and {{Location map+}}. The use of these two parameters is shown in the examples below.
