What letters are used in geography to represent east, west, north and south?

South-South

West-West (West)

North by north

1, east, west, north, south and middle directions:

Southeast, northwest and middle represent five directions of east, west, south, north and middle, corresponding to five elements, five colors and five seasons. It also refers to four branches and centers in China or a certain country. In China:

(1) easternmost point: the intersection of the main channel of Heilongjiang and the main channel of Wusuli River (about 135 degrees east longitude);

(2) The westernmost point: Pamirs (73.5 degrees east longitude);

(3) The northernmost point: the center line of Heilongjiang main channel north of Mohe River in Heilongjiang Province (about 53 degrees north latitude);

(4) The southernmost point: Zengmu shoal in Hainan Province (about 4 degrees north latitude);

(5) The middle, that is, the place of origin, is in the middle of Shaanxi Province.

2, the way to distinguish the direction of the southeast and northwest:

(1) southeast northwest formula: upper north, lower south, left west, right east.

(2) Use a compass to identify the direction, and the initial direction of the compass is set to point north.

(3) use the map to identify the direction. Look at the map on weekdays and get to know the general direction of the subway.

(4) Use the direction of the sun to identify the direction. China is in the northern hemisphere. For most cities in China, it is north of the Tropic of Cancer. The sun rises in the southeast in the morning, sets in the southwest at dusk, and is due south at noon.

(5) Use trees to identify the direction. On sunny hillside, please pay attention to sunny hillside. Observe whether there are any trees that have been cut down and see its annual rings. One side of the sparse arrangement of annual rings is the south, while the other side is the north.

Extended data:

Application of geography: geography uses various methods and techniques, and direct geodesy mapping is particularly important. Aerial photography and artificial earth satellite electronic remote sensing technology have improved the measurement method. Statistical methods are helpful for regional analysis of quantitative data, mainly demographic and measurement data. But cartography has always been a unique means for geographers.

Geography has many uses. It enables people to understand the basic characteristics of the world they live in, the diversity of regions and residents, the complex relationship between people and resources and nature, and the problems faced by people in other countries and regions. Geographical research can explain the distribution characteristics of nature, biology and human beings on the earth and their complex chains.

Practical geographical analysis is very helpful for managing resources, understanding environmental problems, analyzing natural disasters (such as drought and flood) and measuring the distribution of environmental pollution (pollution caused by urban, agricultural and industrial waste discharge). It is particularly important to analyze the adverse effects of dam and reservoir construction on the environment.

Geographers are involved in land use and housing planning. They are also an important force in national and international institutions responsible for research, investigation, development or management of natural resources.
