latitude 3550

Php uses the longitude and latitude of two locations to determine the distance /** * Calculate the distance between two known longitude and latitude, in meters. * @ Param lng1, lng2 longitude * @ Param lat1, lat2 latitude * @ Return float distance, in meters * @ Author yalong sun **/ Function getdistance ($ lng1, $ lat1, $ lng2, $ lat2 ){ // Convert

1. Assume that the Earth is a positive sphere. The longitude and latitude coordinates of point A and point B on the ground are (Aj, Aw) and (Bj, Bw) respectively, and the mean value of the earth's radius R is 6371 km. 2. Create a three-dimensional Cartesian coordinate system:The earth's ball center is the origin O, the ground axis is the Z axis, the Arctic direction is the positive direction of the Z axis, the Equator plane is the X axis and Y axis of

This article mainly introduces how PHP calculates the distance based on the longitude and latitude between two points. The code is very simple, but it is very practical. if you need it, you can refer to this as a good example and paste the code directly, first, you must know the latitude and longitude values. /*** @ Desc calculate the distance * @ param float $ lat

After graduation for several years, even the trigonometric function forgot to know the latitude and longitude of the two points of AC or BC. how can I use php to find the angle of α or beta? thank you! After graduation for several years, I forgot my trigonometric function. We know that the latitude and longitude of the two points of AC or BC are used to evaluate the angle of α or β. How to use php? thank

This example describes the PHP method for calculating the maximum minimum latitude and longitude of 4 corners in the current coordinates of 3 km. Share to everyone for your reference, as follows: $LNG, $lat latitude and longitude $half = 6371; $distance = 3; 3 km $DLNG = 2 * ASIN (SIN ($distance/(2 * $half))/cos (Deg2rad ($lat))); $DLNG = Rad2deg ($DLNG); $dlat = $distance/$half; $dla

Google and Baidu use different latitude and longitude projection methods. Therefore, it is very troublesome to use Google Maps to query standard longitude and latitude and then convert them to a hundred degrees. However, Baidu has launched a small tool to easily obtain the latitude and longitude of a Baidu map at a certain point on the map. That is, Baidu map
