Layers provide a simpler means for overlaying data onto the map in a format that is viewable to the user. The ALK Maps plugin for OpenLayers uses these layers to integrate the data returned from ALK's services with OpenLayers's existing source code in way that allows the developer to seamlessly incorporate ALK Maps into any OpenLayers script.
Layers provided by the ALK Maps plugin are handled in the same way as any other OpenLayers layers.
