Maps mean different things to different people. So what is a map?

John Calkins: A map is an answer to a question.

There are three basic kinds of maps that answer three basic types of questions:

• The Location map answers the question, “Where am I?”
• The Navigation map answers the question, “How do I get there?”
• The Spatial Relationships map answers the question “How are these things related?”
