Orienteering

Page 4: NS1 Orienteering

Orienteering

The object of orienteering is to run, ski,

walk, or mountain bike to a series of

points shown on a map. These points

are called control points.

Page 5: NS1 Orienteering

Course lengths range from less than 1

mile for beginners to 4 or more miles

for experienced orienteers.

Orienteering

Page 6: NS1 Orienteering

Map Reading

Orienteering usually requires the use of

a topographic map depicting the area in

which the course is laid out.

A topographic map is a graphic

representation of manmade and natural

features of a part of the Earth's surface.

Page 7: NS1 Orienteering

Topographic Map

Orienteering maps usually are drawn to

a scale of 1:15,000 or 1:10,000, and have

5-meter contour lines or intervals.

They also show large boulders, cliffs,

ditches, and many other features.

Some of the other features that may be

shown are listed on the next screen.

• Elevations

Page 9: NS1 Orienteering

The most useful

scale for an

orienteering map is:

1:15,000 or 1:10,000

(1 inch on the map

represents 1 mile,

which converts to

15,000 or 10,000

inches on the

ground)

Page 10: NS1 Orienteering

Direction

On most maps, north is at the top, south

to the bottom, east to the right, and west

to the left.

There is a slight difference between the

location of the north pole and that of

magnetic north. This is the variation

angle or declination angle.

Legend

Relief features

of the Earth are

shown in the

margins of

orienteering

maps.

Page 14: NS1 Orienteering

When lines are

close together, they

show a steep slope.

Similarly, when they

are far apart, they

show a gentle slope.

Contour interval is

the distance (feet or

meters) between

lines.

Page 15: NS1 Orienteering

If the map contour interval is 10 feet,

this hill is approximately 130 feet high.

Page 16: NS1 Orienteering

Contour Lines

Brown contour

lines represent

valleys, hills, and

plains.

Spacing between

lines represents a

constant vertical

distance; the closer

the intervals, the

greater the slope.

Page 17: NS1 Orienteering

Contour lines indicate

elevation, in feet or

meters, above sea

level.

Contour lines tell

you the ups and

downs of the land.

Page 18: NS1 Orienteering

Typical

Magnetic

Compass

• A must for orienteering

• Contains protractor in base for reading

magnetic azimuth angles on a map

• Most widely used

Silva Type 3

Page 19: NS1 Orienteering

The orienteering

compass has a

protractor base

and a cord to hang

around the neck

(optional).

Page 20: NS1 Orienteering

During orienteering, first obtain the

magnetic azimuth or bearing.

• Place edge of protractor base along

desired line of travel.

• Turn compass housing until

orienteering arrow aligns with

magnetic north reference lines.

• Turn your body until the red end of

magnetic needle aligns with the

orienteering arrow.

Page 21: NS1 Orienteering

• Determine distances between control

points.

• Determine distances actually traveled.

Distance is Important

in Orienteering to:

Page 22: NS1 Orienteering

Distance on a Map

2cm x 250m/cm = 500m on the ground

If a map has a scale of 1:25000, and a

distance of 2 cm were measured on the

map between two locations, then the

actual distance along the ground would

be:

Page 23: NS1 Orienteering

Distance on a Map

Another method is to lay off the

measured distance on the map along

the graphic linear distance scale on

the map. This can then give you the

desired distance along the ground in

feet, meters, miles, or kilometers.

Page 24: NS1 Orienteering

Distance on a Map

A third method is to use the map scales

printed along the sides of the compass

protractor base. These are often

standardized to read distances along

the ground directly in feet or meters.

Page 25: NS1 Orienteering

In the field, your pace is used to

measure distance. Your pace is the

average length, in meters, of a double

step.

Page 26: NS1 Orienteering

To determine your pace, count the

number of double strides you make on

a 600-meter course. This should be

done while both running and walking.

Page 27: NS1 Orienteering

Several methods of land navigation

techniques may be used. Depending on

the terrain, one of the following methods

may be used:

• The beeline

• The steering mark

• The contour route

Land Navigation Techniques

Page 28: NS1 Orienteering

Beeline

A straight line is followed to the desired

location, by observing terrain features,

without the use of a compass.

Page 29: NS1 Orienteering

Steering Mark

Once the bearing (direction of travel) is

determined, travel to easily identifiable

way-points (steering marks), such as

trees, rocks, or houses along the way.

Page 30: NS1 Orienteering

If you use a contour line as a trail, you

would be traveling parallel to mean sea

level.

This method is

less tiring and

more accurate

than the beeline

method because

up and down hill

travel is minimized.

Contour Route

Page 31: NS1 Orienteering

Aiming Off

In this example, the

orienteer follows an

azimuth slightly to

the right of control

point 3, proceeds to

the stream (the

catch feature), turns

left, and follows the

stream to the

control point.

Page 32: NS1 Orienteering

A Catching Feature

• A linear feature that lies beyond the

control (example: a road or fence)

• Passes by, through, or near a control

• "Saves" you if you should miss the

control and go past it

Page 33: NS1 Orienteering

Attack Point

• A prominent feature near a control

(100 - 150 meters)

• Used to get you close to a control as

quickly as possible

• Numerous attack points on beginner

courses

• Few attack points on advanced

courses

Page 34: NS1 Orienteering

Before You Start

First, stop and look around; then look

closely at your map.

Observe the lay of the land. Find some

fairly distinct feature, or better yet, a

group of features, within view and on

the map.

Can you see any collecting features,

catching features, or handrails that

will help you get to the first control?

Page 35: NS1 Orienteering

• Any linear feature you can follow to

where you want to go

• Examples: a stream, trail, road, fence,

brick or stone wall

Handrail

Page 36: NS1 Orienteering

Slope is the steepness of a hill, usually

expressed as a ratio, e.g., 1 to 15 or

1:15, meaning 1 meter of rise for every

15 meters of horizontal distance.

Slope

Page 37: NS1 Orienteering

Profile

Profile refers to the shape of a hill.

Three general profiles are:

Concave - steeper as it get higher

Convex - steeper at the bottom

Uniform - constant slope from bottom

to top

Page 38: NS1 Orienteering

Weather

An important factor in flat country

Page 39: NS1 Orienteering

The effect of ground cover can be

converted to equivalent amounts

of level ground travel by using a

conversion formula.

The formula involves multiplying

the distance by the appropriate

factor in the following list.

Ground Cover Factors

Page 40: NS1 Orienteering

Types of Cover Factor

Open trail

Waist-high grass

Open forest

Thick brush

Creek-bottom tangles

1

1.5

2-3

5

7-10

This indicates it would take 7-10 times

longer to cover creek-bottom tangles

than it would to jog along an open trail.

Page 41: NS1 Orienteering

Rough Orienteering

• Use map to get general idea of objective

(how far it is and where you want to go).

• Proceed at top speed to collecting

features and continue to the control.

Page 42: NS1 Orienteering

Fine Orienteering

• Requires slower movement and

continually checking map

• Smaller features used as landmarks

• Slow and inefficient for use for entire

leg of course

the finish.

Page 49: NS1 Orienteering

Control Marker

• Usually attached is a

distinctive punch used

as 'proof' you were at

that control marker

• Should be visible from

at least 10 meters away

but not more than 50

Orienteering Activities

Recently, a new orienteering activity has

been added to the list of "O" activities.

This is:

Trail-O – an orienteering course laid out

specifically for handicapped individuals.

Trails are either on firm ground or paved

paths. Once a control point is reached,

the individual must observe specific land-

scape features and make the most

accurate estimates of distance, time of

travel, height and other required items.

Page 100: NS1 Orienteering

Q.17. Why is navigating across flat

forested country more difficult

than in more hilly territory?

Page 101: NS1 Orienteering

A.17. Navigating in flat country is

difficult because there are

usually no prominent features

to use as steering marks or

attack points. Also there are

often marshes, swamps, and

briar patches in the low places.
