The current work is to analyze some of the user's data, each user has a number of records, each record has a user position, is expressed in longitude and latitude.There is also a given database, which stores a number of known locations and their latitude and longitude, with more than 43W of data.Now need to take the user's la
Referring to the online part of the data, they rewrote a convenient access to latitude and longitude information of the class Geo, where latitude and longtitude respectively are latitude and longitude. One of the most important constructors is the incoming place name, which
Get the current phone address, and then convert from latitude and longitude to detailed address (including: Country name-Country code, province, city, street name, postal code, etc.).

In the actual map project will encounter the calculation of distance, here to write, later reference: /*** @author Author: Zhaoliang* @version: v1.0* Date of creation: June 26, 2018 3:32:30* Class Description: Calculate distance according to latitude and longitude*/public class Distanceutil {private static Double Earth_radius = 6378.137; Earth radius/*** Google Maps calculates the distance of two coordinat
This is a simple latitude and longitude conversion into specific address information, supporting international and domestic latitude and longitude conversion.
The effect is shown in the following illustration:

For programmers, there are times when you get latitude and longitude based on your address and location.
The first step: now Baidu search "Baidu latitude and longitude to obtain tools-pickup coordinate system", access to the Web site.
The second step: in the input box you need to find the
(RADLAT1) * cos (RADLAT2) * Power (sin (B/2), 2));
S: = S * Earth_padius;
S: = Round (S * 10000)/10000;
return s;
End
