PHP obtains the data calculation range of the range coordinate based on the longitude and latitude, and can search users. // Computing range, which can be used for searching users 12345678910111213141516171819202122 Function GetRange ($ lat, $ lon, $ raidus) {// calculate the latitude $ degree = (24901 1609)/360.0; $ dpmLat = 1/$ degree; $ radiusLat = $ dpmLat $ raidus; $ minLat = $ lat $ radius

The random image mariadb inserts 0.1 million of the data, including the longitude and latitude, and calls Baidu mapAPI to obtain the data required for a province Project. here, we simulate inserting 10000 of the data. The data includes the longitude and latitude (uploaded by the app). here, you need to call Baidu API to obtain the identity of the latitude and lo

Google Maps(Traffic map) does not show the longitude and latitude of an address. In fact, we have come up with a way to find the longitude and latitude of any location on Google map. FirstOpen Google MapSearch for an address on the top, move the map up and down, and place the address in the center of the map. When you want to find the coordinates that are already in the center of the map, copy and paste th

There are two ways to split the current graph: latitude and longitude split and rectangular split. The domestic drawing standards adopt latitude and longitude split. For details, refer to the national standard "national basic scale Topographic Map split and No. GB/T 13989-92". The main feature of the latitude and longitude split is that the row and longitude nu

The current job is to analyze some of the user's data, each user has several records, each record has a user's location, is expressed in longitude and latitude.There is also a given database that stores some known locations and their latitude and longitude, with more than 43W of data in it.Now you need to take the user's latitude and longitude and known locations for distance matching, if the distance betwe
