What is a Thematic Map?
A map that contains one or more Thematic Layers is termed as thematic map.
What is a Thematic Layer?
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.
What is a Range Thematic Map?
A Range thematic map groups all records into ranges and assigns different colors, symbols, patterns or
line style. For example, if you want to visualize the population of the world by growth rate, you would
shade countries according to their reported growth rate amounts.
Creating a Thematic Map
The Thematic Map tab allows you to apply themes on a map. To create a thematic map, follow the steps
given below:
1. Open the Thematics Map tab.
