The OpenStreetMap contributions in Japan from 2007 to 2014 show a fascinating pattern. Why do you think they look this way?

I think it is because they mapped all the roads and then moved to the details of the country.

They made a lot of imports, too. Before 2011, they imported forests. In 2011, after the tsunami and fukushima desaster, Yahoo Japan gave OSM the ability to import a streets in Japan. But the japanese OSM Community is very active, too.

Like a lot of things the visualized data of Japan may look beautiful – but a close look makes you shiver. I am thinking of the imports I had a look at and for which I assume the most errors still won’t be fixed.

Because of population density? This is what Japan looks like at night, a good proxy for population density within a country (actually population density * prosperity * measures to decrease light polution). Striking similarity, no. It could be interesting to overlay both images and look for outliers. A bit like I believe members of your team did some time back, but using image complexity in stead of population density as a predictor of expected data density.

When did you ship Eric off to North Korea? ;)
