Cartography is the study and practice of making geographical maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively. Cartography addresses the following issues: 1) Setting the map's agenda and selecting traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. 2) Representing the terrain of the mapped object on flat media. This is the concern of map projections. 3) Eliminating characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization. 4) Reducing the complexity of the characteristics that will be mapped. This is also the concern of generalization. 5) Orchestrating the elements of the map to best convey its message to its audience. This is the concern of map design. ... more
