The situation is almost impossible, in which we do not know, where are we. Even the survivors of the plane crash know at least what country or neighborhood they were flying over. Thus, determining the location consists in a gradual narrowing of the probable area of stay, until you find a specific point on the map and eliminate the others. If you can pass, for example by radio, coordinates of the place, in which you are, this will make it easier for the rescue team to search. if you know, on what map to look for a place, where you are, you shouldn't be careful, that you are lost. Referring characteristic points of the landscape, which you see, to those marked on the map, you will locate your location quickly. In this case, the method of gradual narrowing of the alleged whereabouts is very effective. Sometimes you have to make your own map, for example if you do not have a map of the area or this one, you have, it is too detailed.
FINDING YOUR POSITION ON THE MAP
When arranging a place, where you are, you have to relate your position to the landmarks and find their symbols on the map. Use the compass to establish the azimuth, that is, the angle between the north and the direction, in which the characteristic point of the landscape is located. After locating and determining their azimuths, two lines can be drawn on the map, which, by intersecting each other, determine the position of the observer.
1 Point the compass towards some landmark in the landscape, for example a mountain pass. Rotate the compass dial until, when the arrow pointing north on the dial points in the same direction, what a magnetic needle. This way you will find the azimuth.
2 Put the compass on the map, on the symbol for the mountain pass, and move it until it stops, when the arrow on the dial points to North on the map. Draw a line connecting the pass to the site, to which you moved the compass. Its direction is determined by the previously measured azimuth.
3 Point the compass to another, a clearly visible point of the landscape. It should be at an angle of approximately 90 ° to the previous one and at least one kilometer from the observer. The tops of the hills are excellent landmarks.
4 Draw a line on the map from the symbol that marks the top of the hill, according to the method described above. Your position is determined by the intersection of the two lines. You can draw another third line, the measurement will be more accurate.
