The i-delve mapping system allows real-time navigation of Western Australia. The frame on the left is the layer selector. It can specify which 'layers' to turn off and on. For instance, it is possible to turn the roads layer off if it is not neccesary to display it. Some layers can be expanded (denoted by a plus sign) so that only certain parts of that layer will be turned off/on.
The coloured square to the left of the Layer name is the selectability layer. If the selectability is turned off, that is the square is no longer coloured, then the layer will be displayed but cannot be selected.
Certain layers will only be displayed if the map is zoomed to the correct size. These layers will be greyed out in the layer selector frame. If this happens, zoom in or out until the layer becomes active.
The icons at bottom of the map are tools that can be used in the i-delve system.
