First, the map direction:

1, n: North

North; north

south

South; south

3. Female: West

West; West; West; Western countries

4. N: North

North; north

Second, the map direction representation method:

1. Maps with beacons should be identified according to the direction marked by beacons (the arrow points to the north).

2. For maps that don't point to the target, the rule of "up north and down south, left west and right east" is usually adopted to determine the direction.

3. On a map with a latitude and longitude net, determine the direction according to the latitude and longitude net, with the longitude line representing the north-south direction and the latitude line representing the east-west direction.

Extended data

Three elements of a map:

1, geographical elements

Refers to the natural and social phenomena with geographical location and distribution characteristics represented on the map. Therefore, it can be divided into natural factors (such as hydrology, landform, soil quality and vegetation) and socio-economic factors (such as residential areas, traffic lines, administrative boundaries, etc.). ).

2. Mathematical elements

Refers to the mathematical basis of maps. Such as map projection, contour line, isotherm, scale, control points, coordinate network, height system, map framing, etc. These contents are the basis for determining the range and position of the map sheet and controlling other contents. It ensures the accuracy of the map, as a reliable basis for measuring points, elevations, lengths and areas on the map, and ensures the splicing and use of multiple maps in a large range.

3. Completion elements

Mainly refers to some content that is easy to read and use pictures. For example: map name, map number, legend and map information description, as well as various text and digital notes in the map.
