Order of layers
All system elements of each type are on the same layer
The geographic background on a smart map, a custom overlay, or a system element, for example a camera. Layers are all the graphic elements that exist on the smart map.. For example, all cameras are on the same layer. If you hide the camera layer, all cameras are hidden. From top to bottom, layers for system elements are arranged in the following order: locations, cameras, links, and geographic background. You cannot change this order.
The geographic background is always the lowest layer on a smart map. You can switch between geographic backgrounds, but you can select only one geographic background at a time.
Custom overlays are added as separate layers, and are stacked in the order in which they were added to the smart map. You rearrange the order by configuring default settings for the map.
Example
A city planner has a shapefile that shows the city boundaries, and a shapefile that includes all major roads within the city. The planner can arrange the order of layers so that the roads display on top of the city boundaries. This gives a general view of where cameras are in the city, and the ability to zoom in to see the name of the street that a particular camera is on.
