Module:Location map/data/CAN NT North Slave is a location map definition used to overlay markers and labels on an equirectangular projection map of North Slave Region. 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 "CAN NT North Slave":

## Map definition

• `name = North Slave, Northwest Territories`
Name used in the default map caption
• `image = NWT North Slave Region Map.svg`
The default map image, without "Image:" or "File:"
• `x = 46 + 645 * 0.5 * ln( ( 1 + cos(\$1*(pi/180))*sin((\$2+112)*(pi/180)) ) / ( 1 - cos(\$1*(pi/180))*sin((\$2+112)*(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 = 1261 - 1080*(atan(tan(\$1*(pi/180))/cos((\$2+112)*(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

```return {
name = 'North Slave, Northwest Territories',
x = '46 + 645 * 0.5 * ln( ( 1 + cos(\$1*(pi/180))*sin((\$2+112)*(pi/180)) ) / ( 1 - cos(\$1*(pi/180))*sin((\$2+112)*(pi/180)) ) )',
y = '1261 - 1080*(atan(tan(\$1*(pi/180))/cos((\$2+112)*(pi/180)))+0)',
image = 'NWT North Slave Region Map.svg'
