Oceanography By Andrew Rosenberger and Seth Johnson

Maps have been around for several thousand years since 6,200 B.C. Maps have often helped sailors navigate across the oceans. The history of maps has expanded for thousands of years.

How maps have changed over time:
The shapes of maps have changed over time for example: The heart shaped world maps of Apian 1530, the oval shape world map of Rosellie 1508 actually shows the full world and the eye shaped Genoese nautical chart of the world. In our century we use oval shaped maps because it its easier to show the full world. Now thanks to technology like satellites and computers we can have more accurate maps. Sonar technology and submarines help us to discover what the world really is.

History of maps:
People used to think that the world was flat and that the ocean would abruptly end and drop off the edge like a waterfall but instead of more water at the bottom you'd find your doom. If people said that the world was round they would simply hang them. People started the make maps in the early days of 6,200 B.C.Ever since we've been making maps for every thing: cities, states, country's, oceans and the whole world!

Transportation:
Humans have used ships to transport people, cargo and goods for centuries. Without maps sailor wouldn't be able to navigate the oceans. Because when your in the middle of the ocean you can't see land you cant see land marks, only ocean. Without maps in the middle of the ocean would be bad. You would be lost.

Map making:
People called map makers would go and explore unknown lands and oceans and record it on paper to make map sketches. Once they had the maps on paper they would carve it on to wood.Then to copy that map they put bronze on top of it and hit it in to place with a hammer. This was called Cartography. The ancient art of map making. Now days we use satellites to take pictures of the world and send them to our computers to copy it. We then print it on a copy machine.

Conclusion:
Maps have been very important throughout the centuries for sailors. Without maps people wouldn't be able to navigate the circumference of the globe.
