Template:Geobox locator Illinois is a map definition which can be used to overlay a locator dot on an equirectangular projection map of the U.S. state of Illinois. The markers are placed by latitude and longitude coordinates on a map image which matches the borders defined by this template.

Usage[usba ang wikitext]

This template is used by Template:Geobox map and Template:Geobox2 map, supportive templates for infoboxes in the Category:Geobox series.

The {{Geobox}} template uses this map definition when it includes:

map_locator = Illinois

For the locator dot to be correctly placed, {{Geobox}} must also include:

map = Illinois Locator Map.PNG (or one of the other images shown below)

Calibrated map[usba ang wikitext]

The map definition is calibrated to the first image shown below. It will only work with other map images which share the same border coordinates. Plantilya:Stack Plantilya:Stack
