This template overlays a dark polygonal mask on a dynamic map so that the subject area is more clearly delineated. Mask display can be turned on or off by toggling the "GPX tracks / Map mask" layer control.


See Wikivoyage:How to use dynamic maps#Custom districts and tracks for instructions on creating GPX tracks for use with this template.

The points of the mask polygon are marked with {{Mapmask|lat,long|lat,long| ... |lat,long}}

  • Required parameters:
|lat,long pairs of geographical co-ordinates for each corner of the masking polygon.
  • Example:
  • A working example:
View full screen dynamic map for Brooklyn/Downtown
