Mercator Map Projection
The Mercator map projection is the
basic map projection, where there is minimal distortion at and around the
equator but countries like Greenland and Antarctica look very large. This
invention may seem obvious, but in fact it is not. It is specifically
centered on the equator, so the Chinese would have had to know the exact
location of the equator and their location relative to it. This is an
extremely difficult task, given that their instruments for measuring were far
less accurate than those we have today.

The projection demonstrated advanced geographical knowledge. The maps that it was used to produce helped oceanic travelers plot and follow courses to wherever they wanted to go. This helped increase trade and encourage exploration.
Was used to produce maps that helped other civilizations in the same way they helped the Chinese.
