What is a thematic map?
Thematic maps are single-topic maps that focus on specific themes or phenomena
I.e. population density, rainfall and precipitation levels, vegetation distribution, and poverty.
what do thematic maps have that are different than regular maps
have attributes that make spatial patterns more clear, shedding new light on the theme in questions and allowing for further insights.
Why use a thematic map?
Very useful when you want to analyze the spatial distribution of your information, or look for any geographic patterns and trends contained within your data sets.
There are likely a number of important insights contained in your data that may not be evident when viewing it in a spreadsheet. Thematic maps let you visualize your location-based information and bring it to life, making those insights much easier to spot.
