Plantilya:Geobox locator Alabama/doc

Template:Geobox locator Alabama is a map definition which can be used to overlay a locator dot on an equirectangular projection map of the U.S. state of Alabama. 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_locator = Alabama

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

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

Calibrated map

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
