The Piri Reis Map of 1513 is the first surviving map that shows the Americas (the Vinland map may be older but only shows a part of North America). The Piri Reis map shows North America, South America, Greenland and Antarctica which had not yet been discovered. The map was made by a Turkish Admiral Piri Ibn Haji Mehmed. Reis means admiral. Piri Reis did not long bath in the light of this famous work but was beheaded in 1554 for an unsuccessful foray into the Persian Gulf. The map became lost and was only rediscovered in 1929 by a group of historians working in the harem section of the Topkapi Palace in Istanbul (Constatinople) found the map in a pile of rubble.\n\nBecause of the details on this map, many claims have been made for this map. Some even believe that it is so perfect that it could only have been made from very high altitude photographs. Some of this claims can be found at the following web sites:

The first measurement of the equator was done by Eratosthenes of Samos--centuries ago.  He computed it as being roughly 25,000 miles, which is really quite accurate.\n\nEratosthenes was a hotshot at geometry.  He knew that on the spring equinox, the sun cast no shadow at noon in (as I recall it) Syene, Egypt (? on the spelling); in Samos, the shadow at the same time cast a shadow that made an angle of about 6 degrees with the top of the stick.  Using the known distance between the two places, the already accepted fact that the earth was spherical, and a little geometry, he figured out the equitoral diameter, and did a very fine job of it as well.\n\nHe later recomputed the figure, by the way, getting 18,000 miles.  Columbus repeated the calculation, long afterward, and got 19,400.  The Portuguese (the premier mapmakers of Columbus' day) had computed it as about 24,800 or so... They knew the world was round--and bigger than ol' Christopher Columbus thought...  An aside, but a fun one...

Some early navigation maps were used by Pacific islanders. They tend to be very abstract and can be made of sticks and twigs. Apparently they represent ocean swells around islands. These mapping techniques probably go back to the early human travels to the pacific islands, so maps were used 5,000 years ago or so.

The Ancient Greeks knew the world was round.  Their work in mathematics and geography allowed them to calculate the approximate curvature and circumference of the Earth.  The Romans also knew the world was round.  So much of the information from the Classical world was destroyed either during the burning of the library at Alexandria or during the many purges and book-burnings of the Dark Ages.  Much more information was hidden by the Church and forbidden.  Both the Renaissance and the Age of Exploration were about a return to the enlightened times of Classical Europe.  Christopher Columbus theorized that the Earth was not flat, and attempted to sail to Asia in 1492.  He thought he had reached Asia, but it turns out that the Earth was much larger than expected.  He simply re-discovered the Western Hemisphere.

eratosthenes of cyrene (in what is now libya) was an ancient philosopher in the 3rd century BC.  he was able to measure the circumference of the earth and published his details in a treatise called 'on the measurement of the earth'.  the measurement was based on a geometrical argument and a measurement of shadows cast in different places, that assumed a round earth.\n\ni don't know if he was the -first-, but it's the earliest that i'm aware of and is often cited as the 'first'.  it is possible some other scientist had done the measurement earlier, and the results are simply lost in the dusts of time.

He was a map maker before he went out sailing.  For sure it was he who realized that what had been discovered was a new continent, not East Asia, and it was his writings that flew across Europe and made people aware of this new continent.\n\nHe claimed that he knew a new land had been discovered by determining the longitude of the eastern South American continent, but it turns out this claim of his was a lie.  He was something of a rogue...\n\nSo probably, he realized a new land had been discovered because he had been into map making so long that it just came to him.

Mapping.  More directly mapping the world in way computers can use.\n\nMapquest and population displays are two examples

If you are global or visual learner concpet mapping is great for getting the big picture of history. For most global learners, they cannot remember the detail effectively until they have the big picture. It is like building a system of shelves in the mind so you can more easily store and retrive information. \n\nMy kids are using it for their studies with great success, but they are not facing SATs and a tight deadline like you are. But, in the off chance it may help, here are two links that may help you to get started:\n\nsee some examples of history concept maps:\n\nhttp://cmapspublic2.ihmc.us:80/servlet/SBReadResourceServlet?rid=1160861839109_1206028384_10916&partName=htmltext\n\nwhere you can get free concept map software (this is what we are using):\n\nhttp://cmap.ihmc.us/download/index.php\n\nI hope it is of some help.

Well, first of all, back then there were no satellites or airplanes.  There was no way to know what the world "looked like" unless someone mapped it out...specific coastlines, etc.  No one person could do it all...and each of those men were important for learning new things about different parts of the world.  So...the maps were "changed" each time something new was learned.  And, the maps could be changed if someone found something new about an already existing piece of map.  It's sort of like science.  What was known about science and technology 50 years ago is very different than what we know today.  So, as a result, the science books have changed.  If you're 11, chances are the science book you have today is totally different than the one I used a million years ago.  It's the same idea with the maps back in 1492...\n\nThe following link has a listing of all the great historical explorers.  Their biographies and routes, where applicable, are included.  Each link provides even more links...so you should have enough information that it would take you all day to read everything.  Good luck!\n\nhttp://edtech.kennesaw.edu/web/explorer.html

Australia: Meaning, "the South." The first indication of Australia on any map is in a small map of the world which forms the vignette to a Dutch work, Journael vande Nassauche Vloot, under Admiral v'Hermitte, in 1623-4-5-6.

The Nazca lines? I just saw an awesome show on them, and I can't remember what station it was on. National Geographic? TLC? sorry.  I just looked quick on both web sites and couldn't find it.  \nThe conclusion one person interviewed had come up with was that they are maps of underground water sources (the straight lines) and the animals and people figures are the names of these rivers.

The use of grid lines on maps (latitude and longitude) was first suggested by the Greek astronomer Hipparcus about 300 years before Christ. He was the first who devised a method for fixing the location of places on earth by observation of the the sun, moon and stars. He worked out the mathematics of spherical trigonometry, which allowed the results of these observations to be plotted on an earth which he knew already to be a sphere.\n\nLatitude can be found easily by measuring the height of the sun at noon. The measurement of longitude is not so simple as you need an accurate clock.
