  1. 1. USING THE SPATIAL PERSPECTIVEMaps and geography are practically synonymous, and cartography is as old asgeography itself. Maps are used to wage war, to monitor environmental issues, tomake political propaganda, to solve medical problems, for regional planning – inshort, for countless purposes.One of the ways geographers can gain a better understanding of places and issues isby comparing spatial data – maps are the best way to do this.

  12. 12. …. from a functional region. Regions can be seen in a vertical order of hierarchy. Regions, therefore, are ways of organizing humans geographically.
  13. 13. MAPS in the MINDMental maps are a fundamental part of our general knowledge. They develop over years oflooking at wall maps, magazines, and newspapers. They are shaped by our culturalenvironment, which may distort our objectivity. Thus, environmental perception, shapesour mental maps. This is exhibited in studying different living preferences. Considerwhere California students would prefer to live. How would you explain theirpreferences versus ….
