THE LAW OF MAPS • You cannot unfold a GLOBE equally!!! • There will always be some degree of distortion!!! • Types of Distortion: Shape , Size (Area), Distance, or Direction
For each of the following Map Projections consider… 1. What does this map look like? 2. Why is this Map type useful or valuable? 3. Why is this Map distorted or flawed?
