今年是偉大的地圖繪製師麥卡托（Gerardus Mercator）500週年生日紀念，3月4日比利時
舉行了紀念儀式。麥卡托發明了以他為名的投影法，該投影法以數學方式調整緯線比例，
使地圖上的方向與地球的真實方向一致。依靠這種地圖，航海人員可以在茫茫大海中使用
羅盤到達正確位置，對大航海時代的發展起了重大作用。至到今日，海圖仍必然使用該投
影法，市面上的世界全圖，也還很常使用該種投影。

On March 4, 2012, Their Royal Highnesses Prince Philippe and Princess
Mathilde of Belgium were in the town of Rupelmonde to celebrate the 500th
anniversary of the birth of Gerard De Kremer (Gerardus Mercator).During today
’s celebrations the prince and princess placed flowers at the statue of
Gerard De Kremer (Gerardus Mercator), who is best known for Mercator
Projection World Map, in the town square as well as met with dozens of
well-wishers.
Gerardus Mercator was a cartographer. In 1542, he opened a cartographic
workshop. He took the word "atlas" to describe a collection of maps, and
produced the first modern world atlas in 1570.
Mercator is remembered for the Mercator projection world map, which is named
after him. This proved very useful to many later navigators who could sail
across the entire
ocean on approximately straight paths. It became the standard map projection
for nautical purposes because of its ability to represent lines of constant
course, known as rhumb lines, as straight segments.
