__21st Century Maps__

Maps have changed drastically since the 18th and 19th Century. The world was still being discovered. In todays world, practically every spot of the globe has been discovered or explored. Maps were vague and did not hold a lot of information. Today we have satellites, which are big telescopes that orbit the earth in outer space. They can take pictures of any spot on the globe, thus giving us an exact picture of how the world looks. Here are some examples of maps from your century and mine.
 * __Overview__**



As you can see the older map has less description of the world as a whole. Also, notice how The Northwest part of North America is not completely finished because the world had not been completely explored yet. On the left is a map from the 18th Century, and on the right is a satellite image of the world as of 2009.

Here we can see how drastically different the map from the 18th century is compared to the map from the 21st century. As you can see again, in the map on the left, the northwest part of America has not yet been explored. The map on the right shows the 50 states of present day America__. __

The map on the left is a map of geological features of America from the 18th century. The one on the right is present day America. Once again you can see how advancements in technology have made it much easier and more accurate to create maps.

**__Historical Importance__**
====Overall, maps have changed drastically since the 18th and 19th century, and we have advancments in technology to thank for that. But, lets also thanks the many explorers that went out in search of new lands and drew the first maps of the world and America. Its amazing how even though they did not have satellites during your time, they still were fairly accurate in drawing there maps.====
