  1. 1. Chapter 1 Section 2 The Geographer’s Tools Main Ideas & Place and Terms
  2. 2. Main Ideas  Geographers use two and three- dimensional tools to learn about the earth.  Geographers use computer assisted technology to study the use of the earth’s surface.
  3. 3.  Globe- a three dimensional representation of the earth. Problem- Only one half of the world can be seen at any time.
  4. 4.  Map- two-dimensional graphic representations of selected parts of the earth’s surface.  Advantages- Easily portable drawn to scale  Disadvantages- distortion can occur
  5. 5.  Cartographer- A person who makes maps.  Can reduce distortion but using different types of map projections.
  6. 6.  Map Projection- A way of drawing the earth’s surface that reduces distortion caused by presenting a round earth on flat paper.
  7. 7.  Topographic Map- a type of map that represents natural and man-made features on the earth.  Thematic maps emphasize specific kinds of information, such as climate or population density.
  8. 8.  Landsat- A series of satellites that orbit more than 100 miles above the Earth. Each time a satellite makes an orbit, it picks up data in an 115 miles wide. The Landsat can scan the entire Earth in 16 days.
  9. 9.  Geographic Information Systems (GIS)- A digital database that has the ability to combine information from a variety of sources and display it in ways that allow the user to visualize the use of space in different ways.  This could include maps, aerial photographs, satellite images, or other data.
