Understanding Different Types of Maps: Scales, Themes, and Spatial Thinking

This guide delves into various types of maps, their scales, and the purpose behind each style. Explore how map scale represents distance, from representative fractions to verbal and bar scales. Discover the differences between large-scale and small-scale maps, along with reference maps that highlight both political and physical features. Learn about thematic maps, such as choropleth and dot maps, which convey specific data and patterns. Finally, engage in spatial thinking with examples of population density and resource distribution, enhancing your understanding of geographical contexts.

Presentation Transcript

  1. Types of Maps

  2. Map scale • distance on a map relative to the distance on Earth

  3. Representative fraction & Ratio scale 1/50,000 or 1:50,000

  4. Verbal scale – 1in. = 1 mile

  5. Bar scale – black and white line

  6. Large Scale vs. Small Scale

  7. Large scale shows small areas in greater detail

  8. Small scale maps show large areas in less detail

  9. Which map has a larger scale?

  10. Time Zone Maps

  11. Time Zone Maps

  12. Reference Maps Reference Maps shows locations of places, as well as human and natural geographic features. Reference Maps shows locations of places, as well as human and natural geographic features.

  13. Physical maps highlight naturally occurring features

  14. Political maps highlight man made features

  15. Thematic maps – show one theme

  16. Choropleth Choropleth map – uses shading to show different levels of data

  17. Spatial thinking: Why are there higher levels of Latinos in southern Florida?

  18. Spatial thinking: Why are the five red states using the most water?

  19. Dot/Pin Dot Map Dot/Pin Dot Map– each dot represents a number of occurrences

  20. Spatial thinking: Why is most of China’s population near the coast and NE area? • Population density map of China

  21. Spatial thinking: Why do these areas grow corn?

  22. Graduated Symbol Graduated Symbol – uses a symbol to show frequency or intensity of variable

  23. Isoline Isoline map – connects points of equal value to make lines on a map

  24. Ex: Topographic Map

  25. Ex: Weather Map

  26. Cartograms Cartograms show size using data other than area

  27. What statistic was used to draw this cartogram???

  28. Flow Line: shows movement with arrows of different size

  29. Mental / Perceptual Maps • Images of places we form based on our experiences and perceptions • What would your mental map be of: • Austin • Buddhism • Mars
