Chapter 3 Topographic MapsTopography Means: “Shape of the land”
Contour Lines Indicate areas of equal elevationWill 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 LinesTo 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
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! Elevation Change (rise)= Distance (run)= B A Scale (km) 1km
A line that shows the changes in elevation Topographic Profiling A line that shows the changes in elevation across a section of a topographic map.
Contouring: Elevation points have been determined using groundsurveying techniques or GPS but contour lines need to be drawn in.

Interpreting a Topographic Map
Do Now: When would knowing your altitude be important? Today’s Objective: Interpreting a Topographic Map Notes Packet.
Where is this? The cell.
Topographic Maps 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.
Topographic Maps. Lesson Objectives Define a topographic map and state its uses. Define a topographic map and state its uses. Describe how contour lines.
Topographic Maps Topographic Maps: ____________
What are topographic maps?. Topographic maps are also called contour maps A topographic map is a field map where the field value is elevation. Elevation-

Topographic Maps. A.4 B.3 C.2 D.1 What is a Topographic Map? Topographic maps show elevation by using contour lines –These maps would be important.
Topographic Map Vocabulary
Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain.
RULES of Contour Mapping.
Introduction to Topographic Maps
Visualizing Earth’s Surface
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.
Topographic Maps Day 2. Topographic Maps Objective – “I will be able to compare and contrast latitude with longitude.” Essential Question – “Besides the.
Thursday Update SN (Journal Check Next Week!)
Aim: How do we read Topographic Maps? Do Now: In your notes, list all the different types of landforms/features of Earth that you can think of. Example:
Mapping Earth Midterm Review
*these notes go on pages 19 AND 21 of your Plate Tectonics INB!!*
Essential Questions - Topography 1. What information do topographic maps and satellite views provide? 2. How do they predict how land will be reshaped.
The Art of Topographic Mapping Chapter 2: Maps as Models of the Earth.
TOPOGRAPHIC MAPS AND TOPOGRAPHIC PROFILES. CLOSER CONTOUR LINES = STEEPER GRADIENT TOPOGRAPHIC MAPS WOULD BE VERY CLUTTERED IF ALL CONTOUR LINES WERE.
Measuring Earth / Topographic Mapping. Mapping Basics Vocabulary: Contour Interval: the difference in elevation represented by each contour line on a.
Topographic Map Tricks. Trick #1 Contour Lines can never cross or intersect.

TOPOGRAPHIC MAPS Topographic maps show changes in elevation of Earth’s surface. These maps use lines, symbols, and colors to represent changes in elevation.
