The creators of this map overlooked the human impulse to want to physically touch their abstract location – perhaps for comfort, perhaps for emphasis, perhaps for certainty (or perhaps all three factors). The lack of planning for that impulse happens to yield interesting data on the most common route, as well as the most common destination. There is the resulting consequence of a “gap” in spatial knowledge, with the relevant information having slipped away on so many eager fingertips. The sacrifice of functionality clearly imparts lessons about the process of public map design, however. In every mistake, a potential lesson.
