Maps of Standards

Listening to a report about the Trans Siberian Railroad on the radio this morning, my mind drifted to rail gauges, and maps of standards in general.  Here are two that have been of personal interest to me for very different reasons. The first one because I am a rail enthusiast, the second because I used to travel quite a bit within Europe where, in spite of all the European Unionism, there are a lot of AC plug standards.

Some variegated questions for the audience:

  • Is there any correlation between these two standards distributions?
  • Should this type of information be mapped in OpenStreetMap?
  • What’s your favorite map of standards?
