Throughout this blog we’ve been using the acronym PIA for Pole of InAccessibility, instead of POI, which seems to have originated from the first academic paper on poles of inaccessibility by Garcia-Castellanos and Lombardo in the Scottish Geographical Journal.

Alternative PIAs

The same acronym of PIA is used for numerous other meanings.  Here’s a few I’ve come across…
