The Peters's projection is very similar to this Gall projection.
Things or Events
One of the most primary choices is whether to depict the phenomena of
interest as things or as events. Usually, the geographic representation of
things is easier. However, showing phenomena as things makes it necessary
to make more complicated cartographic representations later that show the
relationships among things. For example, showing a traffic jam with a sym-
bol generally suffices to show where the traffic is stopped or slowed down.
How the traffic jam develops, however, cannot be easily shown with this geo-
graphic representation. Modeled as an event, possibly at the level of individ-
ual cars and trucks, the development of the traffic jam can be represented as
a dynamic process.
Patterns or Processes
The choice between patterns or processes is inseparable from the geo-
graphic representation choice of things or events. Still, while it is impossible
to represent a process solely relying on things, it is possible to represent
events as patterns, or to add additional geographic information to the things
to show more of the process. The addition of geographic information to a
geographic representation to support cartographic communication objec-
tives—for example, how a detour for additional traffic decreased the size of
the traffic jam—is a possibility for addressing some of these issues.
