What is cartography?


     Modern cartography is a design process which combines artistic and scientific elements with colour theory, graphic perception, and unique design elements. Altogether these create an aesthetically pleasing whole, which imparts knowledge to the percipient.


     Rapid changes in the field, both in analytical methods and visualization techniques, have pushed cartography past ‘drawing a map’ and into an era where the perception of data can be manipulated to convey a very specific intent, sometimes irregardless of what the data may actually imply.
