# Advice 1: How to determine the latitude and longitude location

Each point on the surface of the earth has a longitude and latitude. If you find these values, you can determine the geographical coordinates of the object. Once in the unfamiliar terrain and lost landmarks in the form of a high hill, or a noticeable tree, calculate the latitude and longitudeto locate them on the map. A map and compass will help you find your way back.
You will need
• watch;
• - protractor.
Instruction
1
First you have to determine geographical longitude. This value shows the deviation of the object from the zero Meridian, from 0° to 180°. If desired point East of Greenwich, the value is called East longitude, if West – West longitude. One degree is 1/360 of a full part of the equator.
2
Pay attention to the fact that in one hour the Earth turns 15 degrees of longitude, and the four minutes goes by 1°. Your watch should show accurate local time. To know the geographical longitude, you need to set the time of local noon.
3
Find a straight stick the length of 1-1. 5 meters. Stick it vertically in the ground. As soon as the shadow from the stick will fall from South to North, and the sundial will "show" 12 o'clock, note the time. This is local noon. Translate the received data to Greenwich mean time.
4
From the result subtract 12. This difference in degree measure. This method is not 100% accurate, and longitude of your calculations may differ from the true geographical longitude of your location at 0°- 4°.
5
Remember, if local noon occurred before noon GMT – this is the East longitude, if later, the West. Now you need to set the geographic latitude. This value shows the deviation of the object from the equator into Northern (North latitude) or South (South latitude) direction, from 0° to 90°.
6
Please note that the average length of one degree of latitude is approximately equal 111,12 km To determine the latitude we need to wait for the night. Prepare the protractor and move the bottom part (the base) on the North star.
7
Place the protractor upside down so that zero degrees was opposite the North star. View, on the contrary what degree is the hole in the middle of the protractor. This will be the latitude.

# Advice 2 : How to determine latitude and longitude on the map

The globes and maps has its own coordinate system. Because of this they can be used to find any object on our planet. Geographic coordinates are longitude and latitude, these angular values are measured in degrees. They can be used to determine the position of the object on the surface of our planet relative of the Prime Meridian and the equator.
Instruction
1
Find parallel, which is the selected object, and determine his latitude. This coordinate defines the angle between the equator and the vertical line at the selected point. Latitude Parallels are marked on the frame geographical maps and is measured from 0 to 90 degrees. In the southern hemisphere latitudes are South and North - North. For example, Cairo (capital of Egypt) is located North of the equator and is located on the parallel of 30°. Consequently, one of its coordinates - 30° North latitude.
2
Learn to determine the latitude of the object if it is located between the Parallels. To do this, define the latitude Parallels are closest to the selected object, and then add to it the number of degrees of the Meridian arc from the object to the parallel. For example, the capital of Russia is located to the North of the parallel of 50°. Between it and the parallel of 6°. It turns out that Moscow is situated at 56° North latitude.
3
Find Meridian, which is the selected object, and determine its longitude. Longitude is the angle between the Meridian on which your property is located, and the initial Meridian. Its value can be between 0 to 180°. Usually the map longitude indicated at the intersections of the equator with the Meridian. Longitude, which is East of the Prime Meridian is called the Eastern, West - West. For example, St. Petersburg is located 30 degrees East of the zero Meridian, so its coordinate 30° East longitude.
4
Try to determine the longitude of the object, located between the meridians. To locate the nearest longitude Meridian with respect to the zero and add the number of degrees of arc Parallels between your object and the Meridian. For example, the Russian capital is 8° East of the Meridian of 30°, then its coordinate is 38° Eastern longitude.

# Advice 3 : How to determine longitude and latitude

If you find yourself away from civilization and were in an emergency situation, first of all you need to navigate the terrain. In some cases it is necessary to determine the geographic coordinates of its location, for example, to transmit their rescue service. There are several relatively simple ways to determine longitude and latitude.
You will need
• Clock, wooden stick, two strips (a protractor), plumb
Instruction
1
For the determination of longitude use the watch, which must be put in place with known longitude. You then detect that the clock at local noon and translate the time difference into degrees. Consider how this works in practice.
2
Set your watch for the time corresponding to the time at the zero Meridian (GMT). Define noon in the area. For this you may need the gnomon – an ancient sundial. Prepare a stick with a length of 1-1,5 m and its vertical stick in the ground. As the movement of the sun do on the earth level corresponding to the length of the drop shadow. At the approach of the sun to the Zenith, the shadow will become shorter. The shortest shadow of the stick will be during the time of true noon. The shadow of the stick at this time will be sent exactly from South to North.
3
Determining local noon, note the clock. Then make the difference the amendment. The fact that the angular speed is not constant and depends on the time of year. So to the result add (or subtract) correction.
4
Let's consider an example. Suppose today is may 2. The clock is set in Moscow. Summer Moscow summer time is different from the world for 4 hours. At local noon, mounted on the sundial, the clock showed 18:36. Thus, the world the time now is 14:35. Subtract from this time 12 hours and get 02:36. Amendment 2 may is 3 minutes (this time should be added). Translating the result in angular measure, will receive 39 degrees West longitude.The described method allows to determine longitude with an accuracy up to three degrees. Given that in an emergency you will not table of the equation of time for the amendment of the calculations, the result may vary from true.
5
To determine the latitude you will need a protractor and a plumb line. Homemade protractor fabricated from two rectangular strips, cementing them in the form of a compass.
6
In the center of the protractor, attach the thread with a load (it will play the role of a plumb). Place the base of the protractor on the North star.
7
From the corner between the base of the protractor and a plumb subtract 90 degrees. We obtained the angle between the North star and the horizon. Since the North star is a deviation from the axis of the pole by just one degree, the angle between the direction of the star and the horizon will be the required latitude of the locality in which you are.

# Advice 4 : How to find latitude and longitude on the map

Any point on the terrain has its own geographic coordinates. With the advent of gps accurate positioning ceased to be a problem, but the ability to understand the map – in particular, to establish the latitude and longitudeis still quite relevant.
You will need
• - A globe or world map.
Instruction
1
If you have a globe, to understand the concepts of latitude and longitude is very simple. But, in its absence, sufficient and normal maps. To start, locate on the globe or the map , the equator and the poles, North (top) and South (bottom).
2
The equator divides the globe (the globe) into two halves: the top, she is North and bottom – South. Note the Parallels – the circle line, encircling the globe along the equator. These lines set the latitude. At the equator it is equal to zero, as you move towards the poles increases to 90°.
3
Locate on a globe or map of your locality – for example, Moscow. Let's see what Parallels it is, you should have 55°. This means that Moscow is at 55° North latitude. North, because it lies to the North of the equator. If you, for example, searched for the coordinates of Sydney, he would have been 33° South latitude, because it lies South of the equator.
4
Now look at the map of England and its capital London. Please note that it is through this town passes one of the Meridian – lines extending between the poles. Near London Greenwich Observatory is, places made to count longitude. Therefore, the longitude of which is the Observatory is 0°. Everything that is West of Greenwich to 180°, refers to the West longitude. That to the East and up to 180° - East longitude.
5
Based on the above, you can determine the longitude of Moscow – it is equal to 37°. In practice, to pinpoint the location of the settlement is determined not only degrees, but also minutes, and sometimes seconds. Therefore, the exact geographical coordinates are: 55 degrees 45 minutes North latitude (55°45?) and 37 degrees 37 minutes East longitude (37°38?). The geographical coordinates mentioned above of Sydney, lying in the southern hemisphere, is equal to 33° 52' South latitude and 151° 12' East longitude.
