No, I stated a hypothetical 'What <br></div><div>if' scenario: "
If everyone on Earth joined OSM ...",</div><div>so the 'locations' are based on the entire <br></div><div>global population derived from:<b>"</b>Center

( maybe not so mad, there is a vast literature</div><div>around this: <a href="http://meipokwan.org/Gallery/STPaths.htm">http://meipokwan.org/Gallery/STPaths.htm</a> <br></div><div>... and some folks have even extended the model into</div><div>'virtual spaces' like WoW ).</div><div><br></div><div>I then sampled some area like the middle of the <br></div><div>Sahara, Siberia, Yukon Territory to get a lower</div><div>bound ( nobody lives here ) and did a blunt</div><div>overly simplified binary classification, and used</div><div>this as a mask to punch out the OSM world map.</div><div><br></div><div>The projection used is psychological, not</div><div>geographical ( <a href="https://en.wikipedia.org/wiki/Psychological_projection">https://en.wikipedia.org/wiki/Psychological_projection</a> ).</div><div><br></div>> ... also a bit surprised that Australia & NZ have <br></div><div dir="ltr">dropped back into the Ocean - I thought there <br></div><div dir="ltr">were a few more of us than that? ..</div><div dir="ltr"><br></div><div>See <a href="http://worldpopulationreview.com/countries/countries-by-density/">http://worldpopulationreview.com/countries/countries-by-density/</a> <br></div><div>Australia is 225 ( out of 230 ) and NZ is 198.</div><div>It's actually even more dramatic than this,</div><div>the Australian Census even has a special</div><div>distinction for remote areas. It's also an</div><div>artifact of the population dataset in</div><div>relation to the resolution of the final</div><div>graphic.

Hägerstrand( et. al. ) is that</div><div>notion of what is 'near' and 'far' for an</div><div>individual and their experiences.
