Chapter 3 Topographic Maps Topography Means: “Shape of the land”
Contour Lines Indicate areas of equal elevation Will never cross or divide
Hill top – Circles within circles Specific points are called Benchmarks
Contour interval Distance between contour lines 500’
Contour Interval Contour Interval = 500’
Indicating all contour lines make it look cluttered – Index Contour Lines To get C.I. : Take the Change in Elevation between two contour index lines and divide that by the number of lines between them.C.I. = 250’
You Try!!! Map A – C.I. = Map B – C.I. =
Benchmark: Exact elevation Marker
Close lines = steep slope
What do you think it looks like from the side? ?
Closed depressions on the land are shown by contour lines with “hachure lines” that point down slope. (indicate holes or craters)
6. A contour line forms a “V” shape pointing upstream when crossing a river or stream. Downhill!!! “V” Shaped Contour Lines
Steep vs Gentle River Direction
Gradient = Average rate of slope Determined by change in elevation divided by distance. Rise over Run! A B Scale (km) 1km Elevation Change (rise)= Distance (run)=
Topographic Profiling A line that shows the changes in elevation across a section of a topographic map.
Contouring: Elevation points have been determined using ground surveying techniques or GPS but contour lines need to be drawn in.

Topographic Maps. What they show… Changes in elevation of Earth’s surface Natural features (mountains, lakes, etc.) Man made features (cities, roads,
Topographic maps are useful because they represent the three-dimensional image of the land by using lines and symbols. 3D image to a 2D map Topographic.
TOPOGRAPHICAL MAPS. Map Scales A map scale is the ratio of the distance on the map to the distance on the earth Eg.1 : map on land This ratio.
What is a topographic map? A topographic map is a map that shows changes and shape in the elevation of land.
TOPOGRAPHIC MAP A MAP WHICH SHOWS ELEVATION OF THE LAND WITH THE USE OF CONTOUR LINES, SHAPES, AND SYMBOLS CONTOUR LINES LINES DRAWN TO CONNECT POINTS.
Where is this?. How would you represent these, or any other landform, on a map? In other words, is it possible to show a three dimensional.
specialized maps which show the highs and lows (relief) of the Earth’s surface.
Topographic Maps. 1.This is what you call the vertical distance between the contour lines. 2.These connect points of equal elevation. 3.Gently sloping.

Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain.
The study of the shapes and features of the Earth’s surface. Map showing 3-dimensional shape and elevation of land in 2- dimensions Height above sea level.
Introduction to Topographic Maps. Topographic Maps Two dimensional model of the Earth’s surface (represents 3-D world) Topographic maps are also known.

Book Definition In your own words… Picture Scale Feature that relates distances on a map to distances on Earth.
Isolines Isolines = lines that connect points of equal values. (iso = equal) The “values” can be anything… temp, pressure, elevation, etc.
