• How much of the map making process can we automate?
• How much about your data can we infer at author-time?
• What cartographic rules can be rewritten?
• Offload tedium and expertise to the software

The Simplest User Experience Wins • What are the core controls that ALL authors need
• What are the controls only ADVANCED authors need
• What can we just do for the author – fewer buttons, not more

#1 Why This Matters
Web Mapping - Finding the Balance (Offering 1362)
There is no single best way to represent data AND, changing the map type, changes the story you tell

Problem #3
Web Mapping - Finding the Balance (Offering 1362)
Color makes or breaks a map… ..and most data sits on tiles, making it even more difficult.

#3 Going beyond ColorBrewer in a tile-based world
Web Mapping - Finding the Balance (Offering 1362)
New Schemes Needed • Reduced Transparency • Not Clash with Tiles • Remain Legible

Problem #4
Web Mapping - Finding the Balance (Offering 1362)
Classification is a product of limited technology, and hard to explain, and hard to defend (but it still has a useful role!)
Let the data speak for itself!
