Land Navigation Flashcards
SAMC Chapter 4
What must be done before you can plot an azimuth on a map?
You must orient the map using a compass to ensure it is aligned correctly with the ground features.
What is the fastest and most accurate way to orient the map?
The fastest and most accurate way is to use the terrain association method, which involves matching map features to those visible in the landscape.
Give two rules to always use when using a compass.
Always hold the compass level to ensure accurate readings.
Avoid proximity to metal objects or electrical sources, which can affect the compass reading.
Can the lensatic compass be used at night?
Yes, the lensatic compass can be used at night, utilizing the luminous sighting slots for navigation.
Where does the arrow on a compass always point?
The arrow on a compass always points to magnetic north.
How many sights does a compass have?
the front sight and the rear sight.
How many degrees are there in a circle?
There are 360 degrees in a circle.
What kind of dial does a compass have?
floating dial
What is meant by the UTM grid system?
The UTM (Universal Transverse Mercator) grid system. A systematic way to identify locations on a map
What is elevation?
Elevation refers to the height above sea level of a specific point on the Earth’s surface.
What is a topographic map?
A topographic map represents the terrain of an area, showing physical features such as elevation, landforms, and vegetation.
Define relief?
Relief is the variation in elevation and slope in a specific area, representing the landscape’s ups and downs.
What are military symbols?
Military symbols are standardized graphical representations used on maps to convey information about units, equipment, and operations.
What is meant by declination?
Declination is the angular difference between magnetic north and true north, which can affect navigation accuracy.
What is vertical distance?
Vertical distance refers to the height difference between two points on the ground, typically measured in feet or meters.
