What does a darker color on a thematic map typically represent?
Higher population or density
Which type of thematic map uses continuous lines to delineate data of the same value, such as elevation and weather maps?
Isoline maps
What is a limitation of choropleth maps?
They assume that the areas shaded have the same value
What is the advantage of graduated symbol maps?
They effectively classify symbols to represent data
Which type of thematic map distorts geographical areas to represent data, for example, by making countries with higher populations appear larger on the map?

Study Notes
Thematic Maps: Types and Definitions
- Thematic maps can be used to understand correlations and patterns in data, including world population distribution.
- Choropleth maps, one of the most common types of thematic maps, use colors to highlight patterns and can display two variables at once.
- Isoline maps use continuous lines to delineate data of the same value, such as elevation and weather maps.
- Cartogram maps distort geographical areas to represent data, for example, by making countries with higher populations appear larger on the map.
- Graduated symbol maps use size and shape to indicate the amount of data at a specific location, making it easier to understand the map.
- Thematic maps have different purposes and pros and cons, and they include isoline maps, cartogram maps, choropleth maps, graduated symbol maps, heat maps, dot-density maps, and flow-line definition maps.
- Isoline maps are beneficial for interpreting gradual changes in data but can be challenging to make and read.
- Choropleth maps are visually effective and easy to read but assume that the areas shaded have the same value, limiting specificity.
- Cartogram maps effectively exhibit numbers but distort geographical areas.
- A graduated symbol map's advantage lies in its effective classification of symbols to represent data.
- Thematic maps can be used to visualize various data, such as world population, atmospheric pressure, gas prices, and hospital locations.
- Thematic maps serve different purposes and are useful for understanding spatial data and patterns in a visually effective way.
