Map Projections and Thematic Maps

The lecture introduces maps, focusing on reference and thematic maps. Reference maps provide specific information like political boundaries, while thematic maps tell stories through data comparison. The lecture also covers spatial patterns, emphasizing clustering and dispersal, and discusses map limitations and distortions, such as those found in Mercator projections.

What is the primary purpose of a reference map?

• To show political boundaries

• To display economic data

• To tell a story

• To compare different areas

Which of the following is NOT a type of reference map?

• Political map

• Subway map

• Choropleth map

• Road map

What distinguishes a thematic map from a reference map?

• It shows the physical location of something

• It uses symbols to represent data

• It tells a story by comparing areas

• It focuses on political boundaries

Which type of thematic map uses color to represent data?

• Dot map

• Choropleth map

• Graduated symbol map

• Cartogram

What does clustering on a map indicate?

• The elevation of an area

• The direction of movement

• The density of something

• How far apart things are

How is absolute distance different from relative distance?

• Absolute distance is a literal measure

• Relative distance is unchanging

• Absolute distance is about economic connections

• Relative distance is a straight line

Why do maps inevitably have distortions?

• They are selective in the information they show

• They are two-dimensional representations of three-dimensional spaces

• They focus on political boundaries

• They use symbols to represent data

What is a common distortion found in the Mercator map?

• Color

• Shape

• Symbols

• Elevation

Which of the following is NOT a type of spatial pattern on maps?

• Clustering

• Dispersal

• Navigation

• Elevation

What is a key takeaway about map projections?

• They are always accurate

• They are three-dimensional

• They never distort spatial relationships

• They selectively show information
