1 Chapter 2 Sections 2-3 Pages Essential Question: How were the regions of Texas identified?

2 Objectives Compare and contrast the different methods of showing scale. Analyze map characteristics to determine the type of map projections. Interpret information from different types of map projections. Compare/contrast general-purpose and special- purpose maps. Categorize maps as being either general- purpose or special-purpose. Infer information about maps.

3 Making the Earth Fit on a Page Maps are models of actual areas Maps are drawn to scale –Scale: relationship between a distance on a map and the actual distance it represents Example: 1 inch = 100 miles Ways to show scale –Bar graph, written scale, fractional scale (see page 34)

4 Cartographers Cartographer: a person who makes maps –Read Then and Now on page 35 –Geradus Mercator (page 33) How do cartographers fit a round surface onto a flat map? –By using map projections to eliminate distortions See picture on page 35 Projection: the transfer of an image of a curved surface onto a flat surface –Plane (used for polar areas) –Cylinder (below the equator areas) –Cone (between polar and low-latitude areas) »Texas is best displayed using a cone projection

7 Common Map Features Map title Scale Location Symbols Legend (Key) –Legend: an explanation of a map’s symbols and scale

8 Types of Maps General-Purpose Maps –Physical Maps: map that shows the natural features of an area They show the topography: features of the earth’s surface and relationship to each other in terms of location and elevation –Example: mountains, valleys, rivers, lakes –Also called elevation maps –Use different colors to represent differences –Political Maps: map that shows boundaries in an area Shows boundaries between counties, states, countries, etc Also identify towns, cities, national parks, state capitals, etc –Physical-Political Maps: shows both topography and boundaries Most classroom maps

9 Special- Purpose Maps –Show info about a specific topic Example: military maps, historical maps, city street maps, natural resource maps, etc
