Module:Location map/data/Africa is a location map definition used to overlay markers and labels on a Lambert azimuthal equal-area projection map of Africa. 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 "Africa":

• `{{Location map|Africa |...}}`
• `{{Location map many|Africa |...}}`
• `{{Location map+|Africa |...}}`
• `{{Location map~|Africa |...}}`

## Map definition

• `name = Africa`
Name used in the default map caption
• `image = Africa location map.svg`
The default map image, without "Image:" or "File:"
• `image1 = Africa relief location map.jpg`
An alternative map image, usually a relief map, which can be displayed via the relief or AlternativeMap parameters
• `x = 48.852459016393 + 71.1 * cos(\$1 * pi / 180) * sin((\$2 - 15) * pi / 180) * (((1 + cos(\$1 * pi / 180) * cos((\$2 - 15) * pi / 180)) * 0.5) ^ - 0.5 )`
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 = 51.180555555556 - 75.3 * sin(\$1 * pi / 180) * (((1 + cos(\$1 * pi / 180) * cos((\$2 - 15) * pi / 180)) * 0.5) ^ -0.5)`
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)

Cairo
Cairo (Africa)
```{{Location map | Africa
| width   = 200
| label   = Cairo
| lat_deg = 30.06
| lon_deg = 31.23
}}
```

### Location map many, using relief map (image1)

Cairo
Lagos
Two locations in Africa
```{{Location map many | Africa
| relief   = yes
| width    = 200
| caption  = Two locations in Africa
| label1   = Cairo
| lat1_deg = 30.06
| lon1_deg = 31.23
| label2   = Lagos
| lat2_deg = 6.45
| lon2_deg = 3.40
}}
```

### Location map+, using AlternativeMap

Cairo
Lagos
Two locations in Africa
```{{Location map+ | Africa
| AlternativeMap = Africa relief location map.jpg
| width   = 200
| caption = Two locations in Africa
| places  =
{{Location map~ | Africa
| label   = Cairo
| lat_deg = 30.06
| lon_deg = 31.23
}}
{{Location map~ | Africa
| label   = Lagos
| lat_deg = 6.45
| lon_deg = 3.40
}}
}}
```

### Creating new map definitions

```return {
name = 'Africa',
x = '48.852459016393 + 71.1 * cos(\$1 * pi / 180) * sin((\$2 - 15) * pi / 180) * (((1 + cos(\$1 * pi / 180) * cos((\$2 - 15) * pi / 180)) * 0.5) ^ - 0.5 )',
y = '51.180555555556 - 75.3 * sin(\$1 * pi / 180) * (((1 + cos(\$1 * pi / 180) * cos((\$2 - 15) * pi / 180)) * 0.5) ^ -0.5)',
image = 'Africa location map.svg',
image1 = 'Africa relief location map.jpg'
}
```
