Main and intermediate sides of the horizon
The sides of the horizon are necessary for orientation on the ground. Four of them are basic: north, south, west, east. The first two point in the direction of the poles through which the Earth's axis passes. The globe revolves around it. The east arrow points in the direction of rotation, and the west arrow points in the opposite direction.
Intermediate sides of the horizon are written in two words separated by a dash (hyphen): northwest, northeast, southwest, southeast. In some cases, this may not be enough to indicate the location of an object.
In this case, its direction will be called a three-word system. The first of them reflects the main side of the horizon, and the other 2 reflect the intermediate side. For example: north-northeast.
What does it mean to navigate?
Studying geography locally is a fun, interesting and useful activity.
To carry out work on the ground, you need to know a lot. For example, it’s good to navigate and measure distances, and take photographs of the area. The ability to navigate plays an important role in a person’s life. There are cases when entire expeditions died due to loss of orientation. And vice versa, this skill has more than once helped people in difficult times. Orientation is determining your location relative to the sides of the horizon, as well as the direction of the path. You can navigate by the stars, the Sun, and local signs.
An invariable assistant in working on the ground is a compass (in the professional speech of sailors, a compass). It serves for orientation relative to the sides of the horizon.
To avoid getting lost in an unfamiliar area (for example, while skiing, hiking, etc.), you must first use a compass to determine in which direction you are going to go. Only in this case will you know which way to return. If you are planning to go to the northeast, then you will need to return back to the southwest.
To correctly determine the sides of the horizon, the compass must be turned so that the blue end of its arrow aligns with the letter “C” (north). If you stand facing north, then behind you will be south, to the right - east, to the left - west. These are the main sides of the horizon. There are also intermediate ones: northeast, southeast, northwest, southwest.
Using a compass, you can easily determine directions to local objects, which can serve as a reliable guide along the way. To do this, determine the azimuths of these objects.
Methods of orientation
Knowing how many ways there are to navigate the terrain, an experienced person will never get lost even in the forest.
Depending on the environment, you need to decide which one to choose. The task is to determine north. In relation to it, you need to choose the desired direction of movement.
You can determine it using different options:
- Compass. Having this device in your hands, you need to position it in a horizontal direction. The arrow will point north.
- Sun. We have to wait until noon. At this hour, all objects cast a shadow to the north.
- Polar Star. This method can be used at night with a clear sky. The North Star always shows the north direction in the sky.
- Trees. There is no need to despair even in the forest. There must always be ways to navigate the terrain. First of all, the location of moss on trees. It grows only on their northern side. An important factor is the density of the branches. On the side where they begin to partake is the south.
- Anthills. They are located only on the north side.
To make it easier to navigate the terrain, you should understand the concept of azimuth . This term refers to an angle formed by lines, one of which points towards the north and the other towards the selected object. The azimuth is found using a compass.
To do this, apply any stick to the body, one end of which is connected to the center of the compass, and the other is directed in the desired direction. The angle between the stick direction and north is called azimuth.

D/z § 61, Questions and tasks /written/
What new things did you learn in the lesson and what did you learn?
Using maps
It is convenient to navigate the area using a map.
This is the name given to the reduced area applied to paper in the form of a picture. For this purpose, a concept called scale is used.
It means how many times the printed image is smaller than the real one.
This can be expressed in two ways:
- A fraction where the numerator is one, and the denominator shows how many times the real distance is reduced.
- After the indicated scale, an explanation is given of how many kilometers are contained in 1 cm of distance on the map.
The second method is convenient for measuring distances without calculations. For this you will need a compass and a ruler.
The disadvantage of maps is the presence of distortions of the real surface. This is due to the spherical shape of the Earth. If you apply its real appearance to paper, you will get tears.
Lesson 2 Orientation
The ability to navigate the terrain is the first condition for a person’s safe stay in natural conditions. Navigating the terrain means being able to:
☛ determine the sides of the horizon and imagine where the south, north, east and west are; ☛ determine your location on the ground relative to local objects, as well as relief forms (hill, ravine, river bank, etc.); ☛ choose the desired direction of movement to get to the intended place; ☛ maintain the chosen direction while moving so as not to stray from the intended path.
When orienting in natural conditions, you must first of all have a good knowledge of the most characteristic local objects along the route (fork in the road, a characteristic bend in the river, a single tree, a forest clearing, etc.), which must be used as beacons indicating your location and the desired direction of movement.
To determine the sides of the horizon, you must be able to use a compass, the sun and a clock, and determine the sides of the horizon by the North Star.
To navigate the area, if the show takes place along a route unknown to you, you must be able to navigate using a compass and map.
Methods for determining the sides of the horizon
The sides of the horizon on the ground can be determined by a compass, by celestial bodies (the sun and stars) and by some signs of local objects.
Note that to determine the sides of the horizon, it is enough to know the direction to the north. If it is known and you stand facing north, then there will be east on the right, west on the left, and south on the back.
The simplest and most reliable device for determining the sides of the horizon is a compass. The most common type of compass is the Andrianov system compass.
In tourist practice, the Sport-3 liquid compass has found the widest use.
To determine the sides of the horizon, you need to place the compass horizontally, release the brake of the magnetic needle and turn the compass box so that the northern end of the magnetic needle coincides with the zero division of the scale. In this position, the compass needle shows the direction north - south and the letters S, S, B, 3 on the compass scale will respectively face north, south, east and west.
Determining the sides of the horizon on the ground can be done by the sun and the clock. This method is less accurate than the first (since our watches do not show local time, but zone time), but for the practice of orienteering on the ground it is quite acceptable. In addition, it is necessary to remember that in Russia the clock hands are moved 1 hour forward and noon (the time when the sun is in the south) for residents of the Northern Hemisphere occurs not at 12 o'clock, but at 1 o'clock in the afternoon (13 o'clock).
Taking this into account, the sides of the horizon based on the sun and the clock are determined in the following sequence: the clock is held horizontally so that the hour hand is directed towards the sun; mentally divide the angle formed between the hour hand and the direction from the center of the dial to the number 1 in half, i.e., draw the bisector of this angle. The line dividing this angle in half will indicate the direction to the south.
The sides of the horizon can be approximately determined by the sun and the clock in another way.
From your geography course, you know that the Earth makes a full revolution of 360° in 24 hours. This means that the sun moves along the horizon from east to west by 15° in 1 hour. Thus, if the sun at noon in the Northern Hemisphere is in the south, what corresponds to 180° on the compass scale, then at 17:00 it will be in the southwest: (17:00 - 14:00) x 15° = 45°; 180° + 45° = 225° - on a compass this corresponds to the southwest direction. At 20 o'clock the sun will move by 90° and will be in the west (180° + 90° = 270°). Thus, by looking at the sun and the clock, you can approximately determine the sides of the horizon.
The sides of the horizon can also be determined by some local objects, including the direction of the clearings and digitization on quarter posts. Clearings in the forest are usually cut almost strictly along the lines north-south and east-west. At the ends of the pillars installed at the intersections of the clearings, the blocks are numbered from west to east (from left to right). Thus, the smallest number is located on the northwest section of the pillar, and the next in order is on the northeast. These two numbers indicate the north direction.
When orienting by local objects, you can use the following characteristics: on the northern side, the bark of single trees is rougher than on the southern side; the trunks of the pine trees turn black from the north after the rain; mosses and lichens cover the northern side of trees, stones, and stumps more abundantly; resin on coniferous trees protrudes more strongly on the south side; The northern part of the anthill is located on the southern side of the trees.
Determining the sides of the horizon at night Determining the sides of the horizon by quarter posts
The easiest way to determine the sides of the horizon at night is to determine by the North Star, which indicates the direction north. To navigate by the North Star, you first need to find the constellation Ursa Major in the sky - these are seven bright stars located in the sky in the form of a large bucket. Mentally draw a straight line through the two outermost stars of the bucket of the Ursa Major constellation, on which mentally set aside from the end of the bucket a segment equal to five distances between these stars. At the end of the segment you will see a bright star, which is located in the constellation (also a bucket) Ursa Minor. This is the North Star. If you stand facing it, then in front there will be a direction to the north, behind - to the south, on the right - to the east, on the left - to the west.
However, even at night, the most reliable way to determine the sides of the horizon is with the help of a compass. When determining the sides of the horizon, it is better to use several methods to avoid mistakes.
Test yourself
☛ Why is it necessary to be able to navigate the terrain? ☛ What are the main elements of terrain orientation? ☛ What is the procedure for determining the sides of the horizon using a compass? ☛ What signs of local objects will help determine the sides of the horizon? ☛ How can you determine the sides of the horizon by the sun and the clock?
Use a compass to determine which direction of the horizon the windows of your apartment (house) face.
In the schoolyard or on a walk, determine the sides of the horizon based on signs of local objects, the sun and the clock, and then compare the results obtained with compass readings and determine the errors of the first two methods
Globe application
Globe is the name of a reduced model of the Earth. It is made in the shape of a ball. Continents, water bodies and the relief of the territory are depicted on it in an undistorted form. The scale is always constant and is 1:50000000. This means that 1 cm contains 500 km.
The entire surface of the globe is covered with meridians and parallels . They are necessary to find the coordinates of any point on the globe. To do this, concepts such as latitude and longitude are used.
Latitude is the angle formed by two lines. One represents the radius of the equator, and the second connects the center of the Earth to a defined point. Depending on the hemisphere, it is northern and southern.
Longitude is the angle formed by two planes. Both pass through the entire axis of the Earth. One of them cuts the planet through the prime meridian, and the second - the one on which the desired point is located. The location of the Greenwich Observatory is conventionally accepted under the prime meridian. It is located near London. Longitude can also be north or south.
The same degree grid is used on maps.
Site plan
Unlike a map, a plan is drawn up for a small area of the area. It may highlight a small object with its surrounding area. Externally, it represents a diagram of a village, collective farm or state farm. Due to the small area, the curvature of the earth's surface is not taken into account.
On the plans, all existing objects are drawn to a given scale. No passes are allowed. Plans can be created manually or using aerial photographs.
There is no degree grid on the plans . The north direction is at the top of the picture.
Possessing such knowledge, you can always get out of a difficult situation if you find yourself in an unfamiliar area. Moreover, it does not matter where she is and what time of day it is at the moment.
