osm geocoding

The so-called geocoding refers to acquiring location information through place names, such as latitude and longitude, detailed addresses, and so on.The so-called anti-geo-coding, refers to the latitude and longitude, altitude and other information to obtain geographical location information.The use of geocoding and anti-geocoding on iOS, if the manual input latit

It is now often necessary to provide some information about location based on the location provided by the user. Sometimes you can directly determine the latitude and longitude of the user, sometimes not necessarily determine the user's latitude and longitude information, the user is through the input of some road name, landmark building or store name location, but our database may not be stored in the user may enter the latitude of these location information, At this point you can use some map-

Geocoding API is a service interface provided by Baidu. It is mainly used to provide translation services from address resolution to latitude and longitude coordinates or from latitude and longitude coordinates to addresses, you can send a request to receive returned data in JSON or XML format. Most of the code and solutions provided on the Internet are based on Google map. In fact, their solutions are similar. Here, I will send a link to show you how

Basically there is no big limit, using the top interface to get latitude and longitude is basically 100% successful, but this coordinate system is GCJ02 coordinates.The result information

Geocoding implementations

---restore content starts---Basic Android itself with the Geocoder this class can also be achieved for the latitude and longitude of the positive and negative Yi, but its own bugs exist a lot, especially in the stability of the resolution here, Google provides geocoding stability more good, although its usage is a little more complex, In fact, its general working principle is the HTTP protocol, Google has an open interface, we will be the latitude and
