This is the documentation page for Module:Location map/data/Hong Kong MTR

Lua error: expandTemplate: template "coord" does not exist.


Module:Location map/data/Hong Kong MTR is a location map definition used to overlay markers and labels on an equirectangular projection map of MTR. 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 "Hong Kong MTR":

Map definition

  • name = MTR
    Name used in the default map caption
  • bottom = 22.226206973395
    Latitude at bottom edge of map, in decimal degrees
  • left = 113.89717393747
    Longitude at left edge of map, in decimal degrees
  • right = 114.282
    Longitude at right edge of map, in decimal degrees
  • mark = Station icon MTR.svg (8px)
    The default mark image to display with this map. This can be overridden by the mark parameter in Template:Location map, which would otherwise default to Red pog.svg (8px).
  • marksize = 12
    The default mark size (in pixels) for the mark image displayed with this map (should not include px, for example marksize=12, not marksize=12px). This can be overridden by the marksize parameter in Template:Location map, which would otherwise default to 8.

Precision

Longitude: from West to East this map definition covers 0.3848 degrees.

  • At an image width of 200 pixels, that is 0.0019 degrees per pixel.
  • At an image width of 1000 pixels, that is 0.0004 degrees per pixel.

Latitude: from North to South this map definition covers 0.3259 degrees.

  • At an image height of 200 pixels, that is 0.0016 degrees per pixel.
  • At an image height of 1000 pixels, that is 0.0003 degrees per pixel.
