Making Great Maps
• Cartography is the art and science of making maps
• Maps are always simplifications of reality
– Simplification is what makes maps helpful when we need to make a decision, explain patterns, or find a bucket of fried chicken
• Maps are designed by people (who have intentions)
so we have to map responsibly

Three Key Questions • Who wants a map?
– Is it 10 experts, or 20,000+ in a MOOC?
• Where will it be seen?
– On a small piece of paper, or in a web map?
• What is its purpose?
– To explain how my town has changed over time, or to help
someone plan a pub crawl?
• Each of these questions deserves a well-thought answer before mapmaking begins

Layout Design
• One of the first steps in mapmaking is to develop a balanced layout
• Map(s), title, legend, scale bar, source text, etc… all need to be positioned and sized relative to one another
• Goal is to shape this general layout design to match the answers to three design questions

Symbolization
• Simplifying reality requires Cartographers to use symbols to represent features
• Points, lines, and polygons can be graphically manipulated to explain data
• Symbolization can emphasize a visual connection to a real feature, or can be very abstract
