Thematic Map Software such as Maptitude can assemble information about map features to create a map that illustrates the patterns in the data. This is called a thematic map. Thematic maps use distinctive colors, symbols, and fill styles to portray data such as population, transit ridership, mode split, or income. The different styles highlight the similarities and differences among map features.
In some kinds of thematic maps, Maptitude changes the appearance of each feature based on its characteristics. In other types of thematic maps, Maptitude displays charts or symbols on each feature to illustrate comparative information. When data are portrayed in a thematic map, the information becomes easier to see, understand, and interpret.

Thematic maps illustrate the characteristics of map features, so that the characteristics are easy to see and understand. A map theme is a styling of map features according to the values of one or more data fields. Choosing the correct theme can be tricky. The table below helps you choose the correct tool for the data you are using.
