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":

## Map definition

• `name = the 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, which can be displayed via the relief or AlternativeMap parameters
• `x = 50.0 + 124.03149777329222 * ((1.9694462586094064-(\$1 * pi / 180)) * sin(0.6010514667026994 * (\$2 + 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 - (\$1 * pi / 180)) * cos(0.6010514667026994 * (\$2 + 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 {{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:

## 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]]
}}
```

### Creating new map definitions

```return {
name = 'the United States',
x = '50.0 + 124.03149777329222 * ((1.9694462586094064-(\$1 * pi / 180)) * sin(0.6010514667026994 * (\$2 + 96) * pi / 180))',
y = '50.0 + 1.6155950752393982 * 124.03149777329222 * ( 0.02613325650382181 - (1.3236744353715044 - (1.9694462586094064 - (\$1 * pi / 180)) * cos(0.6010514667026994 * (\$2 + 96) * pi / 180)))',
image = 'Usa edcp location map.svg',
image1 = 'Usa edcp relief location map.png'
}
```
