Maps are an essential tool for geographers, as they allow them to visualize and analyze spatial data. In AP Human Geography, students are expected to be able to identify and interpret different types of maps. This guide will provide an overview of the most common types of maps used in AP Human Geography, as well as some tips for interpreting them.

Reference Maps
Reference maps are the most basic type of map. They show the physical features of an area, such as mountains, rivers, and cities. Reference maps can be used for a variety of purposes, such as planning a trip or understanding the layout of a region.
- Topographic maps show the elevation of landforms, typically using contour lines. They are useful for understanding the terrain of an area and planning outdoor activities.
- Hydrographic maps show the location of water bodies, such as rivers, lakes, and oceans. They are useful for studying water resources and transportation routes.
- Political maps show the boundaries of countries, states, and other political units. They are useful for understanding political geography and the distribution of power.
Thematic Maps
Thematic maps are used to show the distribution of a particular phenomenon, such as population density, ethnic diversity, or economic activity. Thematic maps can be divided into two main types: choropleth maps and dot maps.
- Choropleth maps use different colors or shades to represent the values of a particular variable across different geographic units, such as counties or states. They are useful for showing the spatial distribution of a phenomenon and identifying patterns.
- Dot maps use dots to represent the location of individual data points. They are useful for showing the distribution of a phenomenon at a more detailed level.
Other Types of Maps
In addition to reference maps and thematic maps, there are a number of other types of maps that are used in AP Human Geography. These include:
- Flow maps show the movement of people, goods, or ideas. They are useful for understanding migration patterns, trade routes, and the spread of ideas.
- Isoline maps show lines of equal value, such as temperature or elevation. They are useful for interpolating data and understanding the spatial distribution of a phenomenon.
- Mental maps are cognitive representations of space that people create in their minds. They are useful for understanding how people perceive and interact with their environment.
Tips for Interpreting Maps
When interpreting maps, it is important to consider the following:
- The scale of the map. The scale of a map tells you the relationship between the distance on the map and the distance on the ground. A small-scale map covers a large area, while a large-scale map covers a small area.
- The projection of the map. The projection of a map is the way that the curved surface of the Earth is represented on a flat surface. There are many different projections, each with its own advantages and disadvantages.
- The legend of the map. The legend of a map explains the symbols and colors used on the map. It is important to consult the legend before interpreting the map.
- Your own knowledge and experience. Your own knowledge and experience can help you to interpret maps. For example, if you know about the history of an area, you can use that knowledge to help you understand the distribution of population or economic activity.
Maps are a valuable tool for geographers, and they can be used to gain a variety of insights into the world around us. By understanding the different types of maps and how to interpret them, you can become a more informed and engaged citizen.
How to Use Maps in AP Human Geography
Maps are an essential tool for AP Human Geography students. They can be used to:
- Understand the spatial distribution of population, economic activity, and other phenomena.
- Identify patterns and trends in human geography.
- Make inferences about the relationships between different factors.
- Develop and test hypotheses about the causes of human behavior.
Here are some specific examples of how maps can be used in AP Human Geography:
- To understand the distribution of population, students can use choropleth maps to show the population density of different regions. They can also use dot maps to show the location of individual cities and towns.
- To identify patterns and trends in economic activity, students can use choropleth maps to show the distribution of different industries. They can also use flow maps to show the movement of goods and services.
- To make inferences about the relationships between different factors, students can use maps to compare the distribution of different phenomena. For example, they can use a map of population density to compare the distribution of poverty.
- To develop and test hypotheses about the causes of human behavior, students can use maps to identify patterns and trends. For example, they can use a map of population density to hypothesize about the factors that affect the distribution of population.
Maps are a powerful tool for understanding the world around us. By learning how to use maps effectively, AP Human Geography students can gain a deeper understanding of the human condition.
Table of Map Types
| Map Type | Description | Example |
|---|---|---|
| Reference map | Shows the physical features of an area | Topographic map, hydrographic map, political map |
| Thematic map | Shows the distribution of a particular phenomenon | Choropleth map, dot map |
| Flow map | Shows the movement of people, goods, or ideas | Migration map, trade route map, diffusion map |
| Isoline map | Shows lines of equal value | Temperature map, elevation map, precipitation map |
| Mental map | A cognitive representation of space that people create in their minds | Map of a person’s neighborhood, map of a person’s school |
Table of Map Projections
| Projection | Advantages | Disadvantages |
|---|---|---|
| Mercator | Preserves the shape of landmasses | Distorts the size of landmasses, especially near the poles |
| Robinson | A compromise projection that balances shape and size distortion | Does not preserve the shape or size of landmasses perfectly |
| Peters | Preserves the size of landmasses | Distorts the shape of landmasses |
| Sinusoidal | Preserves the area of landmasses | Distorts the shape of landmasses |
Table of Map Scales
| Scale | Description | Example |
|---|---|---|
| Small-scale | Covers a large area | World map, continent map |
| Medium-scale | Covers a smaller area | Country map, state map |
| Large-scale | Covers a small area | City map, neighborhood map |
Table of Map Legends
| Symbol | Meaning |
|---|---|
| Blue line | River |
| Red dot | City |
| Green area | Forest |
Conclusion
Maps are an essential tool for understanding the world around us. By understanding the different types of maps and how to interpret them, you can become a more informed and engaged citizen.
