The “Problem” of Map Dimension

Appalachian Trail (ME) Contour View

Pseudo-three dimensional

Same Place – Elevation View

This is still a two dimensional view, but (x,y) has been replaced by (t,z) where t represents

progress on the trail.

Same Place Pictoral Progress

• Pseudo-one-dimensional

• Progress is only linear, but the line meanders and there is stuff adjacent to it

• Note the attribute data on the side

Same PlaceText View

• One dimensional view of the same place

• Note that you can move forward and back

• Debatable as to whether or not it is a map

• Personal Note: It is as good as a map for all but elevation

Final Answer

• If it’s on paper, it’s two-dimensional in at least one sense of the term

• If you keep an open mind, however, you can produce “maps” that convey one, two, or three dimensions
