1.2 The Geographer’s Tools Globes and Maps Globes and Maps Globe—a round ball like the Earth. Mapmakers could show the continents and oceans of the Earth as they really are. Globe—a round ball like the Earth. Mapmakers could show the continents and oceans of the Earth as they really are. What is the problem with the globe? Can you put it in your pocket and take it with you on your way to Walmart? What is the problem with the globe? Can you put it in your pocket and take it with you on your way to Walmart?

1.2 The Geographer’s Tools Geographers invented flat maps Geographers invented flat maps The problem? The Earth is round, but the map is flat. The problem? The Earth is round, but the map is flat. You cannot show a round earth on a flat map without distortion, a change in accuracy of shapes and distances.

1.2 The Geographer’s Tools Getting it all on the Map Getting it all on the Map Mercator Projection—a method of putting a map of the Earth on a flat piece of paper. Mercator Projection—a method of putting a map of the Earth on a flat piece of paper. This map is used by sailors This map is used by sailors On the Mercator Projection Greenland looks bigger than South America. Greenland is actually only one-eighth as large as South America. On the Mercator Projection Greenland looks bigger than South America. Greenland is actually only one-eighth as large as South America. Is known as a conformal map. Shows correct shpaes but not true distances or sizes. Is known as a conformal map. Shows correct shpaes but not true distances or sizes.

1.2 The Geographer’s Tools Interrupted Projection—like a ripped orange peel. Interrupted Projection—like a ripped orange peel. By creating gaps in the picture of the world, mapmakers showed the size and shape of land accurately. By creating gaps in the picture of the world, mapmakers showed the size and shape of land accurately. The gaps make it impossible to figure distances correctly. The gaps make it impossible to figure distances correctly.

1.2 The Geographer’s Tools Robinson’s Projection—shows the size and shape of most of the land quite accurately. Robinson’s Projection—shows the size and shape of most of the land quite accurately. Sizes of the oceans and distances are also fairly accurate Sizes of the oceans and distances are also fairly accurate Robinson’s distortions are around the edge of the map. Robinson’s distortions are around the edge of the map.
