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, 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 map defined as image1 (`Africa relief location map.jpg`) 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)

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
}}
}}
```
