Before the panama canal people from East coast of America who wanted to go to Asia had to either sail around south America which took months or sail towards Asia and go around Africa which took even longer. The panama canal was a short cut right in the middle of central America which cut navigation time in half. Hope I helped. :)
A Cartographer is the person that uses science, technology and art to produce maps.
Prince Henry (Infant D. Henrique of Portugal, Duke of Viseu) known as Prince Henry the Navigator was a pioneer during the Age of Discovery. As navigator he employed cartographers to chart the voyages and encourage this activity by using the skill inviting cartographers to go to Portugal to make maps for the infant that helped him during navigation.
