Earth's track surface. Its value ranges from 0 to 90 degrees. The latitude of a point located north of the equator is north latitude, which is recorded as n. the latitude of a point located south of the equator is called south latitude, and it is recorded as S. The region with the

Mysql functions-distance calculation based on latitude and longitude coordinates in actual Web development, more and more professional algorithms are coming into use in some specific fields. For example, the distance calculation method based on two points of

center corresponding to the zip code, and then calculate the distance between each other based on these latitudes, to estimate the approximate distance between certain groups (for example, the distribution range of hotel passengers-the latitude and longitude corresponding t

can get the following formula to calculate the distance of two points:C = sin (mlata) *sin (MLATB) *cos (mlona-mlonb) + cos (mlata) *cos (MLATB)Distance = R*arccos (C) *pi/180Here, R and distance units are the same, if the use of 6371.004 km as a radius, then distance is th
