Template:Location map 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":

Map definition

  • name = United States
    Name used in the default map caption
  • 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}}, {{Location map many}} and {{Location map+}}. The use of these two parameters is shown in the examples below. Additional examples can be found at:

Examples using location map templates

Location map, using default map (image)

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

Location map many, using relief map (image1)

Template:Location map many

{{Location map many | USA
| relief   = yes
| width    = 250
| caption  = Two locations in the USA
| 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/doc is located in United States{{#invoke:Location map|mark}} {{#invoke:Location map|mark}}
Two locations in the USA
