History of Maps of North America in 16th and 17th Century

Maps of North America were made after Christopher Columbus' journey to North america in 1492.  His pilot Juan de las Cosa made four journeys to the Americas where he was able to draw a chart of the world and put in North america in 1508.  Mercator published the first map of the world which included North America in 1538.  This is what it looked like.

Mercator's friend, Abraham Orelis made the first geographical atlas in 1570.  This is what his view of Americas was in his Atlas.


Gutierrez made more detailed map of the New World in 1562.


Henry Biggs, an Oxford Mathematician, explored the west to have California in it.  This is what the map of North America looked like in 1625 by Briggs.
 
This is North America about 1699.

As North America got more explored and discovered the maps got more detailed as you can see in these maps from the 1500 and 1600's.  The maps also took on a better looking shape as time went on too.
