The Legend tab explains the meaning of the symbols used to represent the geographical elements on the map.
Base Maps are usually combined with other map layers to provide detail and background information to visualize and enhance operational information managed by different organizations.
A selection of Esri World and Microsoft Bing maps are available for use as the base map layer.
Define a set of layers as a “Quick Map” for convenient recall by users. For example, quickly switch between the initial displayed layers to a Parks quick map (which includes all Park layers plus Streets, Parcels, and Hydrography layers for reference).
All map layers and their symbology are listed in the main panel of the Legend.
