Chapter 2 Maps

Topographic map

• Is the map that shows surface features or the topography of the earth.

• It shows both natural features such as rivers lakes and mountains.

• It is also made by human features such cities roads an bridges.

• It also shows the elevation.

Contour lines

• They are lines that connect points of equal elevation.

• One contour lines can connect points on a map that have an elevation of 100ft another one will connect of 200ft.

Page 4: By: Tj Hires

Contour interval

• It is the difference in elevation between one contour line an the next.

• For an example a map with a contour interval of 20ft would have contour lines every 20ft, of elevation change every 20ft.

Index contour

• It is a dark heavy contour line that is usually every fifth line and that is labeled by elevation.

• It is on many topographic maps, the mapmaker uses it to make reading the map easier.

Latitude and longitude

• Latitude lines are imaginary drawn around the earth parallel to the equator.

• Latitude is the distance north to south measured in degrees from the equator.

• Longitude lines are imaginary that pass through the poles.

• They also is the distance east and west measured in degrees from the prime meridian.

Map projections

• They are used to transfer the image of earths curve surface on to the flat surface.

• No Map projections of the earth can represent the surface of the sphere exactly.

• All flat maps have some amount of distortion .
