Use NodeJS to implement the interface for batch query of geographical locations by longitude and latitude.
Steps
1. query interface
There are still many such types of interfaces on the website. I have directly called Baidu map's interface. The interface documentation calls the Geocoding API's geographic code service.
Request example: Perform geographic code query on Baidu building in Beijing

Baidu Map Mobile version of the API contains not only the basic construction map interface, but also integrated a number of search services, including: Location search, peripheral search, range Search, public transport search, ride search, walking search, address information inquiries.
Baidu Map Mobile API provides the search service is mainly through the initialization of the Mksearch class, register the search results of the listening object Mksearchlistener to implement the asynchr
JS to obtain a latitude and longitude implementation method
Above this JS to obtain the latitude and longitude of the implementation method is a small series to share all the content, hope to give you a reference, but also hope that we support the cloud habitat community.
Objective
Recently due to the need for work, need to extract some of the city's latitude and longitude coordinates, a little search, and found that Baidu map and the gold map have provided relevant functions and examples. Then the rest of the work is relatively simple, save the coordinates, and then converted to WGS coordinates, so as to match the existing GPS data and maps.

This is a good example, directly affixed to the code, first of all to know the latitude value, longitude value

This example describes how PHP calculates the distance between two coordinates (longitude, latitude). Share to everyone for your reference. Specifically as follows:
Here you use PHP to calculate the distance between two coordinates (longitude, latitude), and return the result to a meter or kilometer.
function distance ($lat 1, $lng 1, $lat 2, $lng 2, $miles = True)
{
$pi = m_pi/180;
$lat 1 *= $pi;
1. According to the address to obtain latitude and longitude:
Request Address: http://api.map.baidu.com/geocoder/v2/?address= China Chengdu Talent Market output=jsonak= your AK.
Return results: {"status": 0, "result": {"location": {"LNG": 104.06552381979525, "lat": 30.68093376455154}, "precise": 1, " Confidence ":", "Level": "UNKNOWN"}}2. Obtain the address according to the latitude and longitude degree:

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
