Hao Projection: Chinese-Drawn World Map

Maps are political by nature of defining boundaries. Whoever has that authority to classify territory, gains a lot of power.

More interesting than just drawing the lines, however, is the graphical representation of 3D spaces in 2D. Many probably are familiar with the impact of the Gall-Peters map (by Arno Peters based on a 1885 James Gall paper) since the 1980s.

UNESCO promotes the use of the Gall-Peters projection, and this option is widely used in British schools. Boston became the first public school district in the United States to adopt this map as its standard in 2017.

Lately it seems like the Gall-Peters projection opened the door to dynamic maps that try re-frame our understanding of reality in terms of coastline length.

Speaking of coastlines, a report in 2010 by Linda Jakobson at the Stockholm International Peace Research Institute called “China Prepares for an Ice-Free Arctic” shows China’s perspective on sailing through the Arctic.

Then on 11 December 2013 the Chinese Academy of Sciences announced that the researcher (geophysicist) Hao Xiaoguang had drawn another new map of the world.

…with the authorization of National Administration of Surveying, Mapping and Geoinformation. Traditional word map is suitable for expressing the relationship of east and west hemisphere, it uses meridian to cut the global and should be called as merdian-wise world map. As contrary, the new version of world map uses prime vertical to cut the global and should be called as prime vertical-wise world map, consequently, it is suitable for expressing the relationship of north and south hemisphere. In order to express the geography relationship properly, the workshop had proposed the design scheme of series of word map since 2000 to 2002. In recent years, the new version of world map had been applied by many agencies for different scientific purpose, and the draft has been collected by State Museum, From now on, the new word map will be available in our daily life and will give us brand new geography idea.

Saying prime vertical-wise world map is a mouthful (maybe sounds better in Chinese?) and so the Hao Projection might be easier and make more sense.
