Expression of latitude and longitude-"Sixteen-character rule: latitude comes first, longitude comes second, numbers come first, symbols come last"

For example: Beijing (40 degrees north latitude and 1 16 degrees east longitude)

2. Law

In what direction, the value is getting bigger and bigger, which is the degree.

The value to the north is getting bigger and bigger, that is, the north latitude. The farther south, the bigger it is, that is, the south latitude.

The eastward value is getting bigger and bigger, that is, the east longitude. The west is getting bigger and bigger, which is the west longitude. .

3. dividing line

Latitude 2 boundary: the division of the northern and southern hemispheres; High schools and low latitudes. (Note: The equator does not belong to the northern and southern hemispheres)

Longitude dichotomy: east-west longitude division; The eastern hemisphere and the western hemisphere are separate.

Latitude and longitude representation and transformation

Latitude and longitude are expressed in degrees, which can be directly expressed in decimal points, but the decimal points of degrees can also be divided into angular minutes (1 angular minutes equals one sixtieth degree) and seconds (one second equals one sixtieth minute). There are many ways to express latitude and longitude. Here are some examples.

Degrees, minutes and seconds mean (degrees, minutes and seconds)-49 30' 00 "-49 d30m00s.

Minute means (degree: minute)-49 30.0'-49 d30.0m.

The average degree is-49.5000 -49.5000d (usually with four decimal places).
