The Map Layer Window is used to control which map layers are visible on the map. The layers shown in this window can be edited from the Mapping > Map Layers menu, or from the Maps subsection of the Start page.

The icons on this window operate on the selected layer. The order of the layers in the view represents the order of the layers on the map; layers at the top of the list are drawn on top of layers lower down. In the screen shot above, the site markers layer will be drawn on top of everything else.

Entries in light-grey are not currently visible on the map. Entries in black are visible.

The button bar in this window provides the following functions:

• This displays the properties for the selected layer in the Properties Window.
• This displays the legend for the selected layer. See Map Legends for more information.
• This adjusts the map view so that you can see the entire layer on the map.
• This toggles the visibility of the layer. If the layer is to be shown, any data source for the layer will be refreshed if necessary (e.g., it represents signal strength or similar). You can also toggle visibility by double-clicking the layer in the list.
• This moves the layer upwards in the hierarchy.
• This moves the layer downwards in the hierarchy.
• This adjusts the layer's transparency.

Double-clicking a layer, or clicking the icon will force any underlying data source to be refreshed if it needs it. A map layer that is waiting for underlying data to become available is marked with a flashing icon.
