Document Summary
Maps are highly efficient at conveying a sense of patterns/distributions. They serve as storehouses of information about patterns of things across the earth! And they can open our eyes to unsuspected relationships Maps give us a visual image of reality. In transforming the world (reality) into a map, three major factors come into play . What to put on the map (what to select) and what to leave out is ultimately a matter of judgment! They must avoid the trap of communicating too little and communicating too much . Henry beck"s map of the london underground: pruning and selecting. Conclusion: the map is a selective image of reality: Information on a map can be shown by pictographs or by symbols.
