Map-02. geocode,-02 geocodeMap-02. GeoCoding/ReverseGeoCoding) The previous section briefly introduces how to obtain user locations and use longitude and latitude to represent locations. This section describes geographical encoding. First, we need to know what is geocode Concept: Geographic code: it refers to the process of establishing the spatial coordinate relationship between statistical data or address

landmark, which encapsulates detailed geographic location information @ property (nonatomic, readonly) CLLocation * location; region @ property (nonatomic, readonly) CLRegion * region; detailed address information @ property (nonatomic, readonly) NSDictionary * addressDictionary; address name @ property (nonatomic, readonly) NSString * name; city @ property (nonatomic, readonly) NSString * locality; 2. Sample Code: Build the interface in storyboard as follows: implementation code: YYViewControl

. However, most of these services do not have a Python-specific library and are inconsistent with each other's JSON structure. As a geocoder, the disobedient python God made a special geocoding tool to unify the services of these different vendors.

, you can access it like using local resources. For example, when accessing the map service on the server, it is like storing map documents and data locally. Releasing GIS resource as a service is the key for people to access it. Generally, resources are created through ArcGIS Desktop and published as services for the client. The following table lists the services that can be published and the resources required for each service. Service Type Required GIS Resources

The function that returns promise is used to execute an asynchronous operation and solve the latency after completion. var geocode = function( address ) { var dfd = new $.Deferred(); GMaps.geocode({ address: address, callback: function( response, status ) { return dfd.resolve( response );

) (location. getLatitude * 1E6), (int) (location. getlong1_* 1E6); mMapController. setCenter (point ); In the same way, if you know the longitude and latitude of a city, you can set it as the current map center, which enables you to locate the city location. How can you get the longitude and latitude of a city?Baidu Map API provides MKSearch. geocode (String address, String city) is used to search for the location of the specific address of a city. If

of coarse grained software objects (or helper objects) that can be generated and executed on the server. In fact, these extensive objects are built into ArcGIS desktop applications based on the same ArcGIS Engine object, but they provide users with a simple access method to interact with them. Examples of such objects include map servers, geocode servers, and geographic data processing servers. Each type of these objects is displayed as a network ser
