PRESENTATION OBJECTIVES:
Provide participants with an overview of
the 2014 Road Scholars Event

Identify the basic features of
topographic maps
Describe how contour lines are created
and used in USGS topographic maps
Use contour lines to create basic and
advanced map profiles

WHAT IS A
TOPOGRAPHIC MAP?


Slide 5

ACTIVITY 1:
Basic Map Features

In this activity, you will create a map of a cookie


Slide 6

ACTIVITY 1:
Creating a Topographic Profile of a Cookie

In so doing, you will do the following:
Identify the basic features of a
map

Create and use a coordinate
system to locate objects on the
map
Determine the map scale
Create a simple
topographic profile


Slide 7

BASIC MAP FEATURES
Place your cookie in the center of the grid shown on the ‘Creating a
Cookie Profile’ Worksheet.


Slide 8

BASIC MAP FEATURES
Trace the outline of your cookie on the profile sheet. When you finish
tracing the outline, remove your cookie and place it on a napkin
directly above the Worksheet.


Slide 9

BASIC MAP FEATURES
Determine the cardinal directions for your map (North/East/South/West)
and fill in the Compass Rose (four arrows) at the bottom right of the
Worksheet.

Slide 10

BASIC MAP FEATURES
Your compass rose should look something like this.

S


Slide 11

BASIC MAP FEATURES
Identify the height and width of your cookie in squares. How many
squares tall is your cookie from North to South? How many squares of
the grid does it cover at its widest point from West to East?

H= 12.75 Squares
W= 12.75 Squares

N
W

S


Slide 12

BASIC MAP FEATURES
Identify places on the cookie where the surface material is different
(chocolate chips). Use the squares on the map to help you place
objects into your map-find the approximate square on the grid and draw
in the chocolate chip. Shade or color in the chips.


Slide 13

BASIC MAP FEATURES
Create a legend for your map indicating what the chocolate chips
represent (lakes, ponds, ore deposits, etc.)


Slide 14

BASIC MAP FEATURES
Determine the map scale (number of miles/kilometers, etc. one square
is equal to)

BASIC MAP FEATURES
Title your map using a name that indicates the location and type of
features shown in the map.

CONTOUR LINES


Slide 19

CONTOUR LINES
Control points are positions on Earth’s surface and
represented on a map from which measurements
are made.


Slide 20

CONTOUR LINES
Benchmarks (BM) are locations where horizontal
position and elevation have been accurately
surveyed.


Slide 21

CONTOUR LINES
Horizontal control benchmarks on USGS
topographic maps are locations where the
geographic coordinates are certain.

Hotchkiss, CO
Sector 7


Slide 22

CONTOUR LINES
Vertical control benchmarks on USGS topographic
maps indicate the elevation of that control point with
respect to sea level.

Hotchkiss, CO
Sector 5


Slide 23

CONTOUR LINES
Spot elevations- the height of identifiable features
such as mountain summits, road intersections and
surfaces of lakes may also be shown on maps.
Hotchkiss, CO
Sector 3


Slide 24

CONTOUR LINES
On topographic maps, a contour line is a line
representing constant elevation

Hotchkiss, CO
Sector 5


Slide 25

CONTOUR LINES
Contour lines never intersect

Hotchkiss, CO
Sector 6


Slide 26

CONTOUR LINES
Thick contour lines are called Index contours.
Index contours are labeled with a number
revealing the elevation of points along the
line.
Hotchkiss, CO
Sector 6


Slide 27

CONTOUR LINES
Thinner, unmarked contour lines are interval
lines.

Interval lines are used to calculate changes in
elevation using the map’s contour interval
Hotchkiss, CO
Sector 6


Slide 28

CONTOUR LINES
Contour lines are separated by a constant
specified distance- the contour interval


Slide 29

CONTOUR LINES
Points lying between contour lines are interpolated
to determine elevation

Hotchkiss, CO
Sector 6


Slide 30

CONTOUR LINES
Evenly spaced contours form a uniform slope

Hotchkiss, CO
Sector 4


Slide 31

CONTOUR LINES
Widely spaced contours indicate a gentle slope

Hotchkiss, CO
Sector 5


Slide 32

CONTOUR LINES
Contour lines that are close together indicate
a steep slope, a wall or cliff.

Hotchkiss, CO
Sector 2


Slide 33

CONTOUR LINES
Jagged, rough contour lines indicate large
outcrops of rock, cliffs and areas of fracture

Hotchkiss, CO
Sector 1


Slide 34

CONTOUR LINES
V-shaped contours indicate stream beds and
narrow valleys.
The point of the ‘V’ points uphill or
downstream
Hotchkiss, CO
Sector 1


Slide 35

CONTOUR LINES
U-shaped contours indicate ridges
The bottom of the ‘V’ points down the ridge

Hotchkiss, CO
Sector 2


Slide 36

CONTOUR LINES
A ‘saddle’ is a ridge between two hills or summits

Hotchkiss, CO
Sector 1


Slide 37

CONTOUR LINES
‘M’ or ‘W’ shaped contours indicate a location
upstream from stream junctions.

Hotchkiss, CO
Sector 2


Slide 38

ACTIVITY 2:
Creating a Topographic Profile of a Cookie

In this activity, you will create a topographic profile
of a cookie


Slide 39

CREATING A TOPOGRAPHIC PROFILE OF A COOKIE
Return to your Cookie Map


Slide 40

CREATING A TOPOGRAPHIC PROFILE OF A COOKIE
Examine your cookie and
identify ‘changes’ in elevation on
its surface.
Take some time to really look at
it and get the lay of the land


Slide 41

CREATING A TOPOGRAPHIC PROFILE OF A COOKIE
Place tiny dots on the cookie map that indicate
a constant elevation and draw lines to connect
these points of constant elevation.
