Google launched the mobile positioning service "Google aspect" (GoogleLatitude ). Although Google has made a lot of considerations in privacy protection, this service has caused many Internet users to worry about personal privacy. Here I will analyze and discuss some of my own tests.Latitude is mainly used for personal privacy protection.

This article describes how to use the Baidu map API to query the corresponding address information based on a latitude and longitude value (geographic coordinate) and the point of interest (POI) information around the address.The Baidu map mobile edition API not only contains the basic interface for creating a map, but also integrates many search services, including: location search, peripheral search, range search, bus search, Driver/Passenger search

Thinkphp realizes nearby inquiries, such as nearby people and group buying. First, to locate the latitude and longitude of the user. Client-side positioning methods can be located using the Map API or with HTML5 browsers (less stable and less accurate). Then, the current latitude and longitude, and need to search the range of distance, calculate a latitude and lo
As we all know, all kinds of online maps in the country according to the standards of National Bureau of Surveying and mapping to rectify the deviation through latitude, and Baidu map on this basis with their own algorithm to do a two times rectification.
Baidu Map Rectification interface is as follows:

PHP calculates the distance between two specified longitude and latitude locations, which are used to compute the latitude and longitude of a given location, calculate the business area near it, and the distance between a given location and a nearby business district. The following are the specific function codes and usage examples.

Write a PHP script today to starters the region name of the response from the database and then query the name of the kindergarten for accurate latitude and longitude. Each time the resulting latitude and longitude enters the changes in the database.Over 70,000 data takes one hours to complete. I have to say that curl results more quickly than file_getcoents. Not much to say directly on the codePhpdate_defa

1. Assume that the Earth is a positive sphere. The longitude and latitude coordinates of point A and point B on the ground are (Aj, Aw) and (Bj, Bw) respectively, and the mean value of the earth's radius R is 6371 km.
2. Create a three-dimensional Cartesian coordinate system:The earth's ball center is the origin O, the ground axis is the Z axis, the Arctic direction is the positive direction of the Z axis, the Equator plane is the X axis and Y axis of
