For example, Tokyo 50°, north latitude 30°, calculate the distance from this point 10-kilometer East, due west, south, south, four points of latitude and longitude Reply content: For example, Tokyo 50°, north latitude 30°,
2nd B is (LONB, LATB), according to the datum of 0 degrees longitude, the positive value of longitude (longitude), the longitude is negative (-longitude), north latitude takes 90-latitude
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
