Why Learn Land Navigation?
Tracking present location
Determining Distance
Sense of direction
How to read a topographic map
Terrain and map association
Spatial skills
Planning safe, practical routes
And more Navigational skills
The best way to learn LAND NAVIGATION is to get "dirt time", that is, get out there with a map and compass!
Navigation is not about finding yourself after you are lost (although that’s what happens sometimes); it’s about keeping track of your position as you move away from a known point. As you move you have to remain cognizant of the terrain you are leaving, of the terrain you are passing, and of the terrain that is ahead.
Navigation in the wilderness means knowing your starting point, your destination, and your route to get there.
These skills will allow you to venture farther off the beaten path than you ever thought before.
Training and practicing land navigation on foot provides the following everyday navigation (how not to get lost) benefits;
(Where am I ?)
(How far is it and am I there yet ?)
(Where do I want to go and where am I actually going ?)
(Do I understand the map ?)
(What hill or river am I looking at ?)
(Can I mentally visualize the landscape in 3D ?)
(Take a long safe route or a short risky route ?)

11. THESE ARE THE TRAINING MODULES
PART 1 Basic Land Navigation
Module 5 Terrain Relief
THESE ARE THE TRAINING MODULES
Module 1 Lensatic Compass – parts and features, and how to sight the compass by two different methods.
Module 2 Topo Map Margin – what map margin data represents, map care, and how to properly fold a map.
Module 3 Topo Map Scale – map sizes and how it affects amount of detail that will be shown.
Module 4 Topo Map Symbols – you must understand them; to read and speak map language to others.
Module 5 Terrain Relief – shows elevation, indicates terrain features and heights of natural features.
Module 6 Map Information – what a protractor is for and how a map provides four kinds of information.
Module 7 Sense of Direction – lateral drift, current bearing, obstacles, back azimuth, deliberate offset.
Module 8 Resection – locate position with map only. Modified resection is with a map or compass.
Module 9 Intersection & Triangulation – two methods to locate position by compass.
Module 10 Map Speaks Compass Language - there is no need to orient the map to find your position.
Module 11 Plotting Position Coordinates – exact positioning, used to communicate to others with a map.
Module 12 Route Measure – mapping straight-line distance, curvature distance, and slope distance.
Module 13 Pace Count – using ranger pacing beads and estimating hiking speed.
Module 14 Travel Distance Estimation – estimating by 100 meter rule, rule-of-thumb, and by time.
Module 15 Plan to Navigate – in a group or alone, equipment, safety, responsibilities, route selection.
Module 16 Stay on Course – advance reference points and advance baselines.
Module 17 Additional Land Navigation Skills – estimate daylight, conserve energy, blisters, weather insight.
Module 18 Navigating Different Terrain – special environments, featureless terrain, visibility, dense foilage.
Module 19 Night Navigation – night adaptation, protecting night vision, navigate with lensatic compass.
Module 20 Sustainment – maintaining skills, training others, setting up a land navigation course.

THE TOPOGRPHIC MAP
Without ever having been to a particular place, and with out talking to someone who has been there, you can already know quite a lot about it with a map. A map is a graphic representation of the earth’s surface drawn to scale, as seen from above. It uses colors, lines, symbols, and labels to represent features found on the ground.
However, the finest maps available are worthless unless the map user knows how to read them.

15. TOPOGRAPHIC MAP DESCRIPTION
PART 1 Basic Land Navigation
Module 5 Terrain Relief
TOPOGRAPHIC MAP DESCRIPTION
Reading a map is a language composed of lines, colors, and symbols.
Five basic colors are used for Topographic Maps.
Brown (Contour Lines)
Black (Man Made Features, Roads, Trails)
Blue (Water Features)
Green (Vegetation)
Red (Highway and Land Grids)
Two minor colors
Pink (Built up area, civilization)
Purple (Updated Map Information)
Symbols are used to represent the natural and man-made features of the earth.
Lines show relief and elevation; it indicates variations in terrain features and heights of natural features.
Every map has Margin Information about the map.
Maps come in three scale sizes; SMALL, MEDIUM, and LARGE. Which affects the amount of area covered and detail that will be shown.
A map is read for four basic kinds of information.
Direction
Distance
Position
Identification
Maps must be taken care of and properly folded for field use.

17. CONTOUR LINES Example: contour is 20 feet interval A=700 ft B=740 ft
PART 1 Basic Land Navigation
Module 5 Terrain Relief
CONTOUR LINES
A=700 ft
B=740 ft
C=770 ft
D=820 ft
Contour Interval ~ The contour interval is the distance between each contour line. The contour interval is found along the bottom edge, center of the map.
Intermediate Contour ~ a brown line on a topographic map and represents a line of equal elevation.
Index Contour ~ a bolder/wider brown line that has the elevation value marked at various intervals as a part of the line.
Example: contour is 20 feet interval

18. PART 1 Basic Land Navigation
Module 5 Terrain Relief
CONTOUR LINES
There is a dimension to establishing position which does depend on map reading skills.
This is the vertical dimension. On a map it is referred to as “relief”.
Knowledge of the relief of an area is extremely important to a wilderness navigator.
The most graphic technique ever devised to show relief information is the contour line.
If you were to walk a contour line you would never go down hill and never up hill, and eventually you would arrive back where you started.

SUPPLEMENTARY TERRAIN FEATURES:
Cut. A cut is a man-made feature resulting from cutting through raised ground, usually to form a level bed for a road or railroad track. Cuts are shown on a map when they are at least 10 feet high, and they are drawn with a contour line along the cut line.
Fill. A fill is a man-made feature resulting from filling a low area, usually to form a level bed for a road or railroad track. Fills are shown on a map when they are at least 10 feet high, and they are drawn with a contour line along the fill line. This contour line extends the length of the filled area and has tick marks that point toward lower ground. If the map scale permits, the length of the fill tick marks are drawn to scale and extend from the base line of the fill symbol.
