== Alternative map ==

The map defined as '''image1''' (<tt>{{{{BASEPAGENAME}}#invoke:Data|main|Location map/data/USA Alabama|image1}}</tt>) can be displayed by using the ''relief'' or ''AlternativeMap'' parameters in {{tl|Location map}}, {{tl|Location map many}} and {{tl|Location map+}}. {{#if:{{{{BASEPAGENAME}}#invoke:Data|main|Location map/data/USA Alabama|image2}}| The map defined as '''image2''' (<tt>{{{{BASEPAGENAME}}#invoke:Data|main|Location map/data/USA Alabama|image2}}</tt>) can only be displayed by using the ''AlternativeMap'' parameter.}} The use of these two parameters is shown in the examples below. Additional examples can be found at:
