Maps, Lies, MUAP
Overview of Cartography
Study of cartography encompasses:
History of cartography
Science of cartography
Artistic aspects of cartography
Use of both digital and traditional hand technologies for map-making
Importance of Mapping
Mapping is crucial for understanding:
Spatial relationships
Our place in the world
Interpersonal relationships
Cartography integrates art, science, technology, and the societal influence of maps.
Maps can project specific world organizations as natural but inherently involve distortions.
Distortion in Mapping
Example of familiar maps:
Traditional north-up orientation (Arctic at the top and Antarctic at the bottom) creates a false sense of normalcy.
The Earth as a sphere allows for various mapping orientations.
An understanding of geography is essential to grasp how maps facilitate storytelling and personal relationship dynamics with the environment.
Guide Question on Maps and Inequality
Key question posed to engage students:
"What do maps have to do with inequality?"
Importance of engaging with book and video materials to analyze themes of mapping and societal power.
Nationalism and Historical Role of Maps
Maps emphasize and reinforce:
National borders and identities (e.g., logo maps)
Distorted perceptions of size and influence based on geographic positioning in maps (e.g., Mercator map).
The Mercator projection, originally designed for navigation, is often criticized for significantly distorting landmass sizes:
Example: Greenland appears larger than Africa despite being much smaller.
Perception Influenced by Mapping
Maps can distort perceptions regarding:
Importance and power; larger entities perceived as more powerful.
Example of projection limitations influencing real-world decisions (e.g., knowledge of North Korea affecting policy preferences).
Note: Changing map projections will not alone rectify inequalities.
Common Projections and Their Limitations
Mercator Projection
Criticized for:
Distorting sizes of land masses significantly (e.g., Russia and Canada appear larger).
Conceived for navigation; remains useful for immediate navigation purposes, impacting modern applications like Google Maps.
Highlights the organizational biases of map-making choices and their practical applications.
Peters Projection
Benefits of Peters Projection:
Maintains area representation accurately but alters shape.
Critiques of Peters Projection:
Despite its effectiveness, it distorts shapes of landmasses significant enough to create inaccuracy in geographic understanding.
Other Projections (Winkel Tripel)
Offers a balanced compromise between size and shape distortion.
Distortions vary based on distance from equator; smaller circles in terms of geographical implications for northern latitudes.
Concept of Mapping Distortions
All maps contain a form of distortion:
Categories of lies in mapping as presented by Marc von Monnier:
White Lies: Accepted distortions necessary for creating understandable maps (e.g., symbolization, aggregation).
Real Lies: Intentional misrepresentation for deception (e.g., propaganda).
Critical consumption is necessary when interpreting maps, considering the intent of the map and the decisions made by cartographers.
Artistic Decisions in Map-Making
Types of Maps and Their Applications
Choropleth Maps
Uses color shading to represent aggregated data (e.g., GDP, population density); demonstrates aggregated trends but limits intra-unit data interpretation.
Risks misinterpreting close values due to arbitrary categorization.
Proportional Symbol Maps
Visualizes data with varying circle sizes to represent values; beneficial for intuitive understanding but can obscure comparisons across regions.
Cartograms
Intentionally distorts sizes to represent quantity (e.g., population); engages viewers in creative ways but presents challenges for understanding true landmass sizes.
Example: Dynamic cartograms can illustrate trends over time effectively.
Isoline Maps
Connects equal value points, ideal for continuous data representation; useful in physical geography (e.g., elevation, pollution levels).
Lacks effectiveness for data varying by territorial units (e.g., divided by states).
Conclusion and Takeaway
Clarification that maps are not purely accurate; they reflect interpretations and narratives about the world.
Emphasis on the critical assessment of maps as representations of information rather than objective truths.

Maps and White lies (MUAP)
Course Progress Overview
Current week is a transition week towards final content of Unit One.
Topic of discussion this week: Development and Wealth.
Reading Assignments
Main Reading: "Development and Wealth"
Textbook reading; described as drier and more technical.
Purpose: Provides a preview of the trade models discussed in the following week.
Additional Material: "Planet Money Makes a T-Shirt"
Described as engaging and a favorite among students.
Content: Explores the process of making a T-shirt, discussing themes of trade and inequality.
Emphasizes real-world implications of global trade.
Weekly Structure and Expectations
Two reading materials this week: one technical and one engaging.
Guide Number 2 is due Friday; follows format of Guide Number 1.
Encourage students to diligently note questions and answers during lectures as it aids exam preparation.
Upcoming Deadlines and Assessments
Important dates:
Guide Number 2: Due Friday, format mirrors previous guide.
Week Five: First exam scheduled for Friday, February 13.
Exam format includes short answer, multiple choice, matching, and one essay.
Students will have a week to complete the exam; drop-in session on the Tuesday before for questions.
Exam is a stop start type, allowing multiple sessions to complete it, but students must save progress regularly.
Instructor Feedback
Instructors commend efforts on Guide Number 1.
Emphasis on patience with grading; aims for fairness across the board.
Potential improvements will be provided in feedback via Blackboard.
Lecture Content Review
MENAPS Recap
Overview of five types of "white lies" in mapmaking.
Discussion of the Modifiable Aerial Unit Problem (MAUP).
Importance of Map Reading and Interpretation
All maps contain some form of distortion, either intentionally or otherwise.
White Lies: Necessary simplifications to present complex 3-dimensional data in 2D formats.
Real Lies: Intentional deceptions aimed at manipulating the viewer's perception.
Example Discussion: Voting Data Map
Analyzed a map depicting Czechoslovakia's perceived threat to Germany.
Investigation of language used ("small state threatens Germany") indicates propaganda.
Conclusion drawn that maps can both use white lies for real lies, complicating proper interpretation.
Five White Lies in Mapping
Projection - Different types of map projections can distort perceptions. Examples include Mercator projection which inflates certain land masses.
Style - Different map styles influence the data representation. Examples include choropleth, proportional symbol, cartogram, and isoline maps.
Symbolization - The choice of symbols can influence interpretation; symbols must simplify reality without distorting too significantly.
Aggregation - The scale at which data is presented can affect the viewer's understanding, illustrated by the MAUP and voting data outcomes.
Context - Providing necessary surrounding information can enhance or hinder a map's effectiveness. An example includes a complex map void of context that confuses viewers vs. a simplified contextual map that is clear and informative.
Development Discussion
Complexity of defining development and inequality; issues of measurement scale and methods.
Introduction of significant lines like the Brandt line, splitting the global North and South.
Discussion around development metrics: GDP, GNI, Purchasing Power Parity, and Gini Index.
Common Metrics for Development
GDP (Gross Domestic Product) - Total goods and services produced; flawed as it includes negative impacts like environmental disasters.
GNI (Gross National Income) - Considers income from investments abroad.
Gini Index - Measures income distribution and inequality within a population.
Human Development Index (HDI) - Measures quality of life via factors such as income, education, and life expectancy.
Case study example: Argentina showing discrepancies between income and HDI.
Takeaway from Development Studies
No single metric can adequately capture development.
Importance of broadening metrics to encompass inequality, quality of life, and social outcomes alongside economic growth.
Acknowledge that definitions of development vary widely and shape the policies and practices we advocate for.
Class Closure
Reminder that conversations on development and trade will continue next week.
Engage critically with materials, reflect on personal definitions of development, and collect insights from today's discussions.
Thankfulness expressed for participation and engagement.
