Template:Location map China is a location map definition used to overlay markers and labels on an equidistant conic projection map of China. 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 "China":

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

## Map definition

• name = China
Name used in the default map caption
• x = 50.0 + 116.80932603407057 * ((1.9996655301850468-(latitude* pi / 180)) * sin(0.5867115434267053 * (longitude - 104) * 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 + 1.256383 * 116.80932603407057 * 0.02641006622571962 - 1.256383 * 116.80932603407057 * (1.3713469994670882 - (1.9996655301850468 -(latitude * pi / 180)) * cos(0.5867115434267053 * (longitude - 104) * 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 (China edcp 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)

Lua error in ಮಾಡ್ಯೂಲ್:Location_map at line 501: Unable to find the specified location map definition: "Module:Location map/data/China" does not exist.

```{{Location map | China
| width   = 250
| lat_deg = 37
| lon_deg = 100
| label   = Qinghai Lake
}}
```

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

Lua error in ಮಾಡ್ಯೂಲ್:Location_map/multi at line 143: Unable to find the specified location map definition: "Module:Location map/data/China" does not exist.

```{{Location map many | China
| relief   = yes
| width    = 250
| caption  = People's Republic of China
| lat1_deg = 39.91
| lon1_deg = 116.39
| label1   = Beijing
| lat2_deg = 31.2
| lon2_deg = 121.5
| label2   = Shanghai
}}
```

### Location map+, using AlternativeMap

Lua error in ಮಾಡ್ಯೂಲ್:Location_map/multi at line 27: Unable to find the specified location map definition: "Module:Location map/data/China" does not exist.

```{{Location map+ | China
| AlternativeMap = China edcp relief location map.jpg
| width   = 250
| caption = People's Republic of China
| places  =
{{Location map~ | China
| lat_deg = 39.91
| lon_deg = 116.39
| label   = Beijing
}}
{{Location map~ | China
| lat_deg = 31.2
| lon_deg = 121.5
| label   = Shanghai
}}
}}
