Module:Location map/data/Canada Alberta is a location map definition used to overlay markers and labels on an equirectangular projection map of Alberta. 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 "Canada Alberta":
{{Location map|Canada Alberta |...}}{{Location map many|Canada Alberta |...}}{{Location map+|Canada Alberta |...}}{{Location map~|Canada Alberta |...}}
Map definition
name = Alberta- Name used in the default map caption
image = Alberta County Point Locator.svg- The default map image, without "Image:" or "File:"
image1 = Canada Alberta relief location map - transverse mercator proj.svg- An alternative map image, usually a relief map, which can be displayed via the relief or AlternativeMap parameters
x = 50 + 796 * 0.5 * ln( ( 1 + cos($1*(pi/180))*sin(($2+115)*(pi/180)) ) / ( 1 - cos($1*(pi/180))*sin(($2+115)*(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 = 516.2 - 489*(atan(tan($1*(pi/180))/cos(($2+115)*(pi/180)))+0)- 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:
- Template:Location map#Relief parameter
- Template:Location map+/relief
- Template:Location map#AlternativeMap parameter
- Template:Location map+/AlternativeMap
