calculate latitude and longitude from distance and bearing

In the MySQL database, how to obtain the distance between them according to two known latitude and longitude, can be realized by other methods, but if you add a stored procedure (built-in function) to MySQL, it is convenient to call MySQL's built-in function directly. The functions are as follows: CREATE definer= ' root ' @ ' 127.0.0.1 ' FUNCTION ' get_product_

PHP calculates the distance between two longitude and latitude Function getDistanceBetweenPointsNew ($ latitude1, $ longitude1, $ latitude2, $ longitude2 ){ $ Theta = $ longitude1-$ longitude2; $ Miles = (sin (deg 2rad ($ latitude1) * sin (deg 2rad ($ latitude2) + (cos (deg 2rad ($ latitude1 )) * cos (deg 2rad ($ latitude2) * cos (de

PHP calculates the distance between two coordinates (longitude, latitude) and returns the result as meters or kilometers function distance ($lat 1, $lng 1, $lat 2, $lng 2, $miles = True) { $pi = m_pi/180; $lat 1 *= $PI 80; $LNG 1 *= $PI 80; $lat 2 *= $PI 80; $LNG 2 *= $PI

From Google Map on the basis of latitude and longitude for the Earth's surface to achieve the distance between two points, slightly adapted for the domestic space distance calculation, the implementation has been sufficient to meters as a unit. net2.0,c# implementation. public static double distanceoftwopoints (double
