AdvancedScaleOverlay - geosolutions-it/MapStore GitHub Wiki

This widget creates a panel for showing an advanced ScaleLine control with:

1. ComboBox for selecting the map scale.
2. Mouse Position (using the OpenLayers Control)
3. Scale Bar (using the OpenLayers Control)
4. ComboBox for selecting scale bar units

Likewise the default ScaleOverlay widget in MapStore you can enable multiple units for the scale bar using the configuration below in your configuration file:

"scaleOverlayUnits":{
    "bottomOutUnits":"nmi",    
    "bottomInUnits":"nmi",    
    "topInUnits":"m",    
    "topOutUnits":"km"
}

By default the standard ScaleOverlay tool in MapStore is used, so in order to enable the 'AdvancedScaleOverlay' you have simply to add the following configuration property to the configuration file:

"scaleOverlayMode": "advanced",
