Plantilya:Geobox locator Illinois2/doc

Template:Geobox locator Illinois2 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

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 = Illinois - outline map.svg

| map_background = Illinois - background map.png

| map_locator = Illinois2

Calibrated map

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