distance between two gps coordinates

Php calculates the distance between two coordinates (longitude and latitude). The coordinate longitude is used. Php calculates the distance between two coordinates (longitude and latitude). This article describes how php calculates the distance between two

Search for nearby locations, for example, within 500 meters of coordinates (39.91, 116.37), first figure out the range of coordinates for the "500 meters near the given coordinates". Although it is a circle, we can first find out the circle's external square, and then take the square latitude and longitude range to search the database. The red part is the require

Keywords: space geometryUse: There will always be a place to use it.Article type: C + + function display@Author: V_shawn@Date: 2016-11-19@Lab: [Email protected]For two straight lines within a space A, I assume they must not be parallel or intersect. If it is known that a on two points A1, A2,b on the two points B1, B2, then it is easy to get two straight lines of the equation.The function can then be called to solve the result:The following is a class for solving this problem:#include How to use
