Photo of the Day: 3D Taiwan Population Density Map | Taiwan News

TAIPEI (Taiwan News) – A British professor on Monday (May 4th) created this fascinating three-dimensional map of Taiwan showing its population density.

Map creator Alasdair Rae, 43, told Taiwan News he used a software tool called Aerialod to generate the topographic population density map based on published global human settlements (GHS) demographic data. by the EU. Rae said he created the relief map of the population on Monday and posted it on Twitter on Tuesday, May 5.

Rae, professor of urban studies and planning at the University of Sheffield, originally from Scotland, said the large squares in the grid are 100 square kilometers, while the small raised boxes are around one square kilometer. When asked what his inspiration was for designing the map, Rae said, “Understanding, analyzing and visualizing population density is part of what I do as a professor of urban studies and planning”.

Many internet users have observed that the graph is the reverse of an ordinary relief map, as the mountains are the flattest areas due to the small population, while the plains of Taiwan have grown into towering peaks. To give an extra sense of realism and three dimensions, Rae added shadows to the back of the population mountains to produce a sort of “sunset effect.”

The highest peak is clearly the Taipei-Keelung metropolitan area in the north, followed by Taichung in the center, Chiayi and Tainan in the southwest, and Kaohsiung in the south. In contrast, cities such as Yilan, Hualien and Taitung appear as small molehills in the sparsely populated northeast and east of Taiwan.

Rae said the highest peaks on the map include the areas of Keelung, Taipei City, New Taipei City, Chiayi City and Taichung City, as the neighborhoods in these cities have the most densely populated kilometer cells, including the more inhabited contain at least 20,000 people in a single cell.
