Golang and php calculate the distance between two latitude and longitude. golang latitude and longitude This article describes how golang and php calculate the distance between two latitudes. We will share this with you for your reference. The details are as follows: Golang version:Copy codeThe Code is as follows: package mainImport ("Fmt""Math")Func main (){Lat1: = 29.490295Lng1 := 106.486654Lat2: = 29.615

Preliminary research topic: give the latitude and longitude range (rectangular or circular) quickly from the large quantities of latitude and longitude in batches to remove information points. The method currently taken from the database can be resolved, but the amount of information is limited. A lot of data appears to be slower. If the generation of text files based on the index to find should be able t

According to the current location of the coordinate point is also latitude and longitude, find the database near 5 km or 10 km near the implementation of all information, after looking for information, it is my sophomore school, is to find the string length, math forgot, did not think math is so useful, math ah really use too much. Use what cosine, angle, radian all forget, but by looking for data, or realized, the error is relatively small, I impleme
