In development, you need to obtain the current city. I use AMAP, but some cities are located incorrectly. for example, if Chengdu is located in Shenzhen, is there any other way to locate the current city, for example, if you use html5 to obtain the longitude and latitude of a city, you need to obtain the current city in development. I use AMAP, but some cities are located incorrectly. for example, if you us

You can search for Google methods on the Internet. However, the Baidu method cannot be found. After querying the API, I finally found it. Let's go! The API in Google maps is Map. fromlatlngtodivpixel (pointer) Methods provided by Baidu API Coordinate Transformation Method Return Value Description Pixeltopoint (pixel: pixel)

Baked from somewhere else, you try it out, you can calculate it, but the correct is not quite understand.Use [Niaoren]GO/****** object:userdefinedfunction [dbo].

When you use the built-in LocationManager and Location of Android to obtain a location, the Location is often null, and the operation is not very convenient, in this Demo, I used the location SDK In the Baidu map API to get the longitude and latitude of the current location and detailed address information at one time,

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. Main problems and Solutions S

I did not know this for a long time. I forgot it. I saw it in a book before. But what I found on the Internet was actually a spherical distance algorithm. Lat is the latitude, and lung is the longitudeA = Lat1-Lat2 is the difference between two points of latitude B = Lung1-Lung2 is the difference between two points of longitude;6378.137 (KM) is the earth's radiu
