Spectrum Spatial Analyst allows you to apply themes on maps. Thematic mapping allows you to analyze your data and display it in a variety of ways on a map.
A map that contains one or more Thematic Layers is termed a thematic map. A Layer on the map that has had its visual style altered to represent data associated with that map layer. For example, a Layer might contain suburb boundaries and have associated information about the total population of each suburb. A Thematic can be applied to this Layer so that each suburb is displayed in a different color depending on how large the population of the suburb is?
Note: The Thematic Map feature is available on the basis of settings done in Admin
Console.
