How can you explain the differences? Does it have something to do with the reason for making each map? Which map is better for communicating? Patterns and Processes One of the most interesting things about maps is that because the paper and drawing won’t change by itself after you make it, you have to show things, such as a house or store, in the same way as you show processes—for example, the way you walk to a bus stop or drive a car to work. If you use multiple colors you can separate things and events, but remember the map doesn’t show the process, it only shows an event that corresponds to the process.
5. Is every map reliable enough for every use? No, maps are abstractions that focus on a selection of things and events from the endless complexity of the world. 6. How do representation and communication relate to each other? Representation is the basis for communication. It is impossible to have a cartographic representation of what is missing from a geographic representation. 7. Why can’t GI or a map show everything in any chosen area without distortion? Maps must abstract, which leads to distortions.
