We can use the Haversine formula to calculate the distance between two points given their latitude and longitude coordinate. The Haversine formula is a mathematical formula that is used to calculate the great-circle distance between two points on a
} 调用 And here's an example of the function in action, using two coordinates in New York City: $point1=array('lat' => 40.770623, 'long' => -73.964367);$point2=array('lat' => 40.758224, 'long' => -73.917404);$distance= get_distance_between_points($point1['lat'],$point1['long...
(it bulges around the equator and is not perfectly symetric) There is an algorithm used in the aerospace industry to compute the distance between two points on the earths surface. Do a google search on "Sedonos Equations". It gets very complicated... Some aerospace companies have patented ...
Points: 38 More actions October 20, 2020 at 2:53 pm #3799300 Hi Robert, Depending on how you plan to use the lat-long calculator for miles, it works great for "as the crow flies" calculations. Unfortunately, not so great for distance calculations for auto or truck mileages. You probab...
This uses the ‘haversine’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the points (ignoring any hills they fly over, of course!).Haversineformula: a = sin...
