Methods of identifying directions in the field, 8 methods of identifying directions in the field

The following methods are commonly used to identify directions in the field:

1. Always refer to the map and compass, and actively observe the surrounding terrain and the plants around you to determine the correct location.

2. Take advantage of the sun.

In winter, the sunrise position is south-east and the sunset position is south-west; In summer, the sunrise position is north-east and the sunset position is north-west; Around the spring and autumn equinoxes, sunrise is due east and sunset is due west.

As long as there is the sun, you can use the watch to discern the direction. Read the moment in 24-hour format and divide the number of hours by two to get one hour. Place the watch horizontally on your hand or on the ground, so that the watch is aligned with the direction of the sun at this moment, and the direction of the watch at 12 o'clock is north, and the direction at 6 o'clock is south.

Immediately, a pole is erected vertically on the ground, the shadow points northwest in the morning, and the shadow points northeast in the afternoon, and the shadow is shortest at noon, when the shadow points due north.

3. Use the stars.

Aim for the North Star. First of all, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by 5 times, and then you can find the North Star in this straight line, and the direction of the North Star is due north.

4. Use the ground features to judge the direction.

Large, free-standing trees usually have dense foliage and smooth bark on the south side, and sparse branches and rough bark on the north side. The south side is usually grassy, and the north side is moist and mossy.

For buildings and mounds, snow melts slowly in the north, while in depressions such as earth pits, the opposite is true.

The doors and windows of the larger temples in northern China, the main entrance of the pagoda and the independent houses in the countryside are mostly open to the south.

The northern edge of the forest glade is more grassy. The annual rings of the stump section are generally spaced at a large interval in the south and a small interval in the north.

In the grasslands of northern China, there are many northwest winds in desert areas, and many snow dragons and salons are often formed near the grass, with large heads and small tails, and the direction of the head is northwest.

The doors of the yurts on the steppe are mostly open to the south. The sparse foliage side is south and the dense side is north.

The stump has a dense growth ring, and the side is north.

Put the pin in a puddle with grease and point to the north.

1.The sunny side (i.e., south-facing) of a single tree is dense, while the shady side (i.e., north-facing) is sparse.

2.In dense forests, the south side of the rock is drier, while the north side of the rock is wetter and mossy.

3.Peach and pine trees secrete gum in the south.

4.The rings of the stump are sparse in the south-facing half and denser in the north-facing half.

5.The parts that are difficult for the volume of snow to melt, such as ravines or rocks, are always in the north-facing direction.

6.The ant's burrow is mostly south of the tree, and the hole mouth faces south.

7.Some natural villages are generally concentrated on the south side of the mountain, and most of the gates open to the south. Generally, ancient temples, ancient pagodas, ancestral halls and other buildings are located in the north and facing south.

8.If you can see the stars in the night sky, as long as you find the Big Dipper, you can find the bright North Star along the extension line of the "spoon handle", and the direction of the North Star is due north.

Look at the sun, the sun is in the east in the morning and the sun is in the west in the afternoon. Looking at the canopy, the place where the canopy is generally lush faces south.

There is a compass, and if it doesn't work, there is a compass.

The 8 methods of identifying directions in the field are as follows:

Method 1: You can find a tree stump to observe, and the width of the growth rings is south.

Method 2: Find a tree with lush foliage on the south side and sparse on the north side; In general, plants have more dense foliage on the sunny side, and moss often grows on the trunks on the sunny side.

Method 3: Observe the ant's burrow, most of which are facing south.

Method 4: After winter snow in the middle and high latitudes, the melting rate of the snow is different in different directions. In the northern hemisphere, the snow melts at a slower rate than on the south-facing side, and we can distinguish the north-south direction according to the degree of snow melt on the north and south sides of the feature.

Method 5: In a place with many rocks, you can also find an eye-catching rock to observe, the mossy side of the rock is the north side, and the dry and bare side is the south side.

Method 6: Identify the direction according to the direction of the doors and windows of the house.

Houses built in the northern hemisphere are designed to sit north and face south to get plenty of sunlight. Therefore, we can roughly distinguish the north-south general direction according to the direction of most houses and the orientation of doors and windows.

Identify the direction of the defense according to the direction of the doors and windows of the house.

Method 7: Use the stars to find the direction.

1) Orient according to the sun:

During the day, when you are in the field, if you don't have a compass or other instrument with you, you can directly use the sun to determine the direction. Since ancient times, people have known to distinguish directions based on the direction of the sun rising in the east and setting in the west. However, the sun really rises in the east and sets in the west during the year, and there are only the spring and autumn equinoxes.

For the mid- and high-latitude regions of the Northern Hemisphere, the Sun is in the southern sky for most of the day, and the shadow of the object is always oriented north (including northwest, due north, and northeast), and at noon the shadow of the object is due north, so the direction can be discerned based on the shadow of the object.

Orient the sun according to its rise and setting (latitude 40).

Look for the North Star according to the constellation Ursa Major.

On a clear night, use the North Star to find your way. Polaris is located in the sky due north, and if you can find Polaris, you will find the direction of true north, and the other directions will be easy to determine.

The famous constellation Ursa Major has 7 major bright stars, which are spoon-shaped, often called the Big Dipper, also known as the spoon star. First find the two bright stars of the Big Dipper, Tianxuan and Tianshu, connect them with imaginary lines, and extend the connection segment in the direction of Tianshu by about 5 times, and you can see a bright star, which is the North Star.

Look for the North Star according to the constellation Ursa Major.

Look for the North Star according to the constellation Cassiopeia.

Cassiopeia is a famous constellation consisting mainly of 5 bright stars in the shape of the letter W. Three of the stars are brighter, and along the middle of the three bright stars, there is an imaginary line with a fainter star in front of it, and on the extension of the line, there is a bright star, which is the North Star.

Method 8: You can also use the watch to identify the direction: in the northern hemisphere, the watch is horizontal, the hour hand points to the direction of the sun, before 12 noon, press clockwise, along the angle between the hour hand and the 12 o'clock scale line to the direction of the angle bisector is south; After 12 noon, counterclockwise, the bisector of the angle between the hour hand and the 12 o'clock scale is south.

Pro, the method is as follows: 1. The watch direction finding "hours fold half to the sun, 12 refers to the north", generally between 9 a.m. and 4 p.m. can quickly identify the direction, with half of the time pointing to the direction of the sun, 12 hours is the north, such as the time of 14:40 in the afternoon, half of which is 7:

20, the hour is pointed towards the sun, then 12 refers to the north, or the watch is flat, and the hour hand points to the sun. 2. Use the sun The skills to find the right distance must be accumulated through the usual field activities. For example:

It is a habit to refer to a map and compass at all times, and to actively observe the surrounding terrain and plants to determine the correct location. The sun rises in the east and sets in the west, which is the most basic way to identify the direction. 3. Use the compass (referring to the north needle of the sail) to open the compass or place the north needle horizontally to center the bubble, and after the magnetic needle is stationary, the black end marked with "n" refers to the north.

You can prepare a small compass with a clear degree of engraving, some of the mini compasses sold on the market are very easy to confuse, and the better one is a liquid fill-in-the-blank type for the best match, and you must be sure that there is no leakage when buying, and there are no bubbles in the surface.

In the field, there are ways to identify the direction from the stump, the hail on the stump, the annual rings, the compass, and the clock.

1. Looking at the annual rings from the stump, the interval in the north is small and dense, and the interval in the south is large and sparse.

2. Use the compass to identify. Put the compass flat and see which letter is rotten in the direction of the magnetic needle n pole to directly determine that the north is **.

3. In the weather with the sun, it is a good way to point the bisector between the hour hand and the twelve o'clock in the direction of the sun, as long as you have a watch.

Judging by features:

1. Large trees can be used, independent large trees usually have lush branches and smooth bark facing south, and sparse branches and rough bark facing north. The south side is usually grassy, and the north side is humid and mossy.

2. Using hungry wheels such as buildings and mounds, the snow in the north melts slowly, while the opposite is true in depressions such as soil pits.

3. Taking advantage of the topography, in China, if there is snow in the valley, the side of the mountain that melts the snow first is the sunny slope (south-facing slope), and the other side is the opposite.

1. Use the watch to see the direction.

Direction finding of the watch: Facing the sun in the direction of half of the time, the 12th hour is north, such as the time of 14:40 in the afternoon, half of which is 7:00

20, the hour is directed to the sun, then 12 refers to the north, or the watch is flat, the hour hand points to the sun, and the reverse extension of the hour hand and the 12-hour bisector is the north;

Note: This method should not be used around noon in areas between 20°30 north and south latitudes, that is, based on the meridian of standard time, add 1 hour for every 15° to the east and subtract 1 hour from 15° to the west.

2. Take advantage of the sun.

The sun rises in the east and sets in the west, which is the most basic way to identify the direction.

It can also be measured by the shadow formation method of the wooden stick, when the sun is enough to form a shadow, a straight stick (more than 1 meter) is erected on the flat ground, and a stone is placed on the top of the shadow of the wooden stick (or other marker), and the shadow of the wooden stick will move with the movement of the sun.

After 30 to 60 minutes, place another stone on top of the shadow of the stick again. Then draw a straight line between the two stones, and in the middle of this line a straight line that intersects perpendicular to it. Then step on the first marker point with your left foot and the second marker with your right foot.

At this time, the front of the person standing is due north, the back is due south, the right hand is east, and the left hand is west.

3. Use the stars.

At night, the North Star appears in the northern sky, it is above the North Pole of the Earth, almost facing the Earth's axis, and its position is almost unchanged from the Earth, so seafarers and travelers often rely on it to find their way on a sunny night.

4. Use plants.

Due to sunlight, the foliage on the south side of the tree is usually more dense than the foliage on the north side. The bark of trees is generally smoother in the south and coarser in the north, and some trees have many cracks and bumps on the bark on the north side, so as long as you carefully observe which side of the tree's branches and leaves are more lush and which side of the bark is rougher, you can distinguish the north and south.

5. Snow melting. A snowdrift where the snow on the south side melts more easily. Even on a cloudy day and you can't see the sun, the snow in the south still melts first, so you can judge that if you get lost in a snowy place, you can see the snowdrifts melt to judge that ** is south.

If you get lost in the cave and get late, you can see which side of the mountain has more snow at the top of the mountain.

Nowadays, there are many friends who like to travel in the wild, so what if you get lost? Here are 6 ways to identify directions in the wild. Take a look below.

In the early morning hours, remember that the direction of sunrise is east. Now you are facing east, which is the direction of the sunrise. It's easy to know that the direction of the left hand is north, the direction of the right hand is south, and behind you is naturally the west!

The most convenient way to identify directions with a compass is a compass, but sometimes a compass of poor quality is unreliable. To purchase a quality*** compass, lay it flat when using the compass.

Using a tree, you can find a stump in the forest and orient it according to its rings, as its rings are always wide in the south and narrow in the north. The rainy season can be determined by the coarse branching of the branches. The green side of the socks is more exposed to sunlight, so it's on the south side; The northern half of the canopy is naturally affected by the sunshine, as it is shaded by the southern half, so the leaves become thinner.

watch, you can also use the watch to identify the direction: your time is divided by 2, then the quotient is the quotient with the sun, and the 12 directions on the dial 12 are north.

Buildings are direction-sensitive, and there are very few buildings in the wild, but if there are any, they can help us orient ourselves. Usually, the building faces south and the façade faces south.

Rocks, where there are many rocks, you can also look for striking rocks. The rocky side of the rock side is on the north side, and the dry bald side is on the south side.

Observe the direction of the sun, the sun rises in the east and sets in the west.
