Projections Cartographers use projections to make maps. A map projection is made by transferring points and lines on a globe’s surface onto a sheet of paper. Copyright © McGraw-Hill Education Types of Maps
Projections A Mercator projection is a map that has parallel lines of latitude and longitude. It clearly indicates direction in straight lines. It is used for the navigation of ships and planes. Types of Maps Copyright © McGraw-Hill Education
Projections A conic projection is made by projecting points and lines from a globe onto a cone. It has a high degree of accuracy for limited areas. It is used to make road maps and weather maps. Types of Maps Copyright © McGraw-Hill Education
Topographic Maps Topographic maps are detailed maps that use contour lines, symbols, and colors to represent changes in elevation and features on Earth’s surface. Types of Maps Copyright © McGraw-Hill Education
Topographic Maps A contour line connects points of equal elevation on a topographic map. The difference in elevation between two side-by-side contour lines is called the contour interval. Types of Maps Copyright © McGraw-Hill Education
Topographic Maps Index contours are contour lines labeled with a number that indicates the elevation. Depression contour lines have hachures, or short lines at right angles to the contour line, to indicate the direction of elevation change. Types of Maps Copyright © McGraw-Hill Education
Geologic Maps A geologic map is used to show the distribution, arrangement, and type of rocks located below the soil. It may also show geologic features such as fault lines. Types of Maps Copyright © McGraw-Hill Education
Geologic Maps Three-dimensional mapsWhen scientists need to visualize Earth three-dimensionally, they often rely on computers to digitize features such as rivers, mountains, valleys, and hills. Types of Maps Copyright © McGraw-Hill Education
Map Legends A map legend explains what the symbols on a map represent.Types of Maps Copyright © McGraw-Hill Education
Map Scales Verbal ScalesA map scale is the ratio between distances on a map and actual distances on the surface of Earth. Verbal Scales When referring to maps, verbal scales are statements used to express distance. Types of Maps Copyright © McGraw-Hill Education
Map Scales Graphic scales Fractional scalesGraphic scales consist of a line that represents a certain distance. These are the most common types of map scale. Fractional scales Fractional scales express distance as a ratio between two units of the same type. Types of Maps Copyright © McGraw-Hill Education

Maps are flat models of 3-D objects. All flat maps distort the shapes and areas of land masses to some extent. We will talk about 4 types of maps: Mercator.
