There are many methods to determine the direction and position in the field. The following are several common methods.
(1) Compass: This is the easiest way. Place the compass or compass horizontally to center the bubbles. After the magnetic needle is stationary, the end marked with "N" refers to the north. 
· Try to keep it level. ?
· Do not get too close to the magnetic substance. ?
· Do not mistake the S end of the magnetic needle as north, causing a 180 degree direction error. ?
· Master the magnetic declination of the active area and correct it.
(2) Sun: When there are few clouds during the day, the sun can be used to determine the direction. The shadow of an object under the sun moves from west to east, making it easy to judge north and south. On a clear day, you can easily know the East and West according to the sunrise and sunset.
(3) Shadow clock method: In the sun, put a wooden stick vertically on the flat ground. When the position of the sun changes, the shadow of the stick moves with the change of the position of the sun. These shadows are the shortest at noon, and the line at the end is a straight line. The vertical line of the straight line is the north-south direction.
(4) Watch method: If you have an old-fashioned watch on your hand (referring to the hour and minute hands), we can use it to determine the direction. Two methods:
â‘ Place the watch horizontally, the hour hand points to the sun, and the bisector between the hour hand and the 12 o'clock scale indicates the north-south direction.
â‘¡ Divide your time by 2, and then align the obtained quotient to the sun. The direction indicated by 12 on the dial is north. For example, at 10 o'clock in the morning, dividing by 2 quotient is 5, align 5 on the dial with the sun, and the direction 12 points to is north. ?
note?
· When judging the direction, the watch should be placed flat. ?
· It is not suitable to use around noon in the area between 20 ° 30 ′ south and north latitude. That is, according to the longitude of the standard time, every hour 15 ° eastward will add 1 hour, and westward 15 ° minus 1 hour. ?
· The time should be calculated according to the 24-hour timing method.
(5) Plant features: If you get lost on a cloudy day, you can get the orientation by plant features. Trees The direction in which the leaves grow lush is south. tree stump The side with the wider annual ring is the south. rock The mossy side of the rock is the north side, and the dry and bare side is the south side. hillside The low ferns and vines on the north side are more lush than the sun. houses Generally the door opens south, especially in northern China. temple It usually opens the door to the south, especially the main building in the temple complex. Highlight features The north base is humid and may grow low bryophytes. Ant cave Most of the ant's holes face south.
