“Recalculating” is a term that many of us are far too familiar with. We hear it when the GPS navigation system on our phone is telling us how to get from Point A to Point B, but we somehow managed to miss the turn. It is hard to imagine a time when maps were unable to give accurate directions in real time. Modern maps are expected to be flawless and up-to-date. So, what happens when maps are wrong?
Maps drawn centuries ago often contain inaccuracies that seem painfully obvious to viewers in the present day. For example, let us consider A New Map of the North Parts of America Claimed by France Under Ye Names of Louisiana, Mississippi, Canada, and New France with Ye Adjoyning Territories of England and Spain. (What a mouthful!) Produced in 1720 by Herman Moll, this map was a direct response to an earlier French map entitled Carte de la Louisiane du Cours du Mississippi that claimed French ownership over portions of the Southwest and the Carolinas. Moll’s map, by contrast, attempted to assert British ownership over the Carolinas. However, Moll’s map contains numerous mistakes:
- California is portrayed as an island
- Florida is much too small
- the Great Lakes are far too large
- all the rivers in Texas flow north and south
- non-existent mountain ranges are depicted in western Texas
