Templat:Location map Chad/doc

Map of Chad

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

• {{Location map | Chad | ...}}
• {{Location map many | Chad | ...}}
• {{Location map+ | Chad | ...}}
• {{Location map~ | Chad | ...}}

Map definition

• name = Chad

  Name used in the default map caption

• image = Chad location map.svg

  The default map image, without "Image:" or "File:"

• image1 = Chad relief location map.jpg

  An alternative map image, usually a relief map, can be displayed via the relief or AlternativeMap parameters

• top = 23.95

  Latitude at top edge of map, in decimal degrees

• bottom = 6.95

  Latitude at bottom edge of map, in decimal degrees

• left = 12.85

  Longitude at left edge of map, in decimal degrees

• right = 24.6

  Longitude at right edge of map, in decimal degrees

• x = ({{{3}}}-12.85)*8.5106382978723

  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 = ({{{2}}}-23.95)*-5.8823529411765

  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 (Chad 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:

Template:Location map#Relief parameter Template:Location map#AlternativeMap parameter

Template:Location map+/relief Template:Location map+/AlternativeMap
