Presentation Transcript

  1. Maps

  2. 3-D Sphere to 2-D Sheet

  3. Many different ways to project the spherical Earth onto a flat sheet of paper…

  4. Cylindrical Mercator Projection This projection stretches out the areas near the poles to make the lines of longitude parallel to each other from equator to poles - this makes Greenland appear much larger than it really is. The map has to be cut somewhere in order to lay flat – in this case right through Eurasia!

  5. Circa 1490 – World Mapdrawn by German cartographer Martellus

  6. Circa 1539 – Scandanavia:a populated area yet sea monsters are drawn in the North Sea

  7. Circa 1580drawn by Ortelius – part of what is considered the 1st modern atlas
