Location map of Alberta

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)) ) )

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:"

• 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
