For example, for the terminal of IOS operating system, when determining target location in China, the mesh is got
After the latitude and longitude information of cursor position, lost if carrying out anti-geographical parsing to the latitude and longitude information using the map software of China
It loses, then service parsing interface in IOS SDK can be used to call (the geographical parsing of other geographic areas of apple geography analysis service
Service) carry out anti-geographical parsing.
According to some embodiments, the target location is being determined not in the boundary polygon of the designated geographic area, it can be with
Anti- geographical parsing is carried out to the latitude and longitude information using the geographical analysis service of other geographic areas.
According to some embodiments, the geography in coordinate system used in the latitude and longitude information and the designated geographic area
When coordinate system used in analysis service is inconsistent, coordinate transformation used in the latitude and longitude information can be specified for this
Coordinate system used in geographical analysis service in geographic area.
For example, the WGS84 coordinate systems of international standard are used using the latitude and longitude information that GPS positioning system is got,
And certain map software uses GCJ02 coordinate systems or BD09 coordinate systems, if necessary to fixed to the GPS using the map software
The latitude and longitude information that position acquisition of information arrives carries out anti-geographical parsing, then needs WGS84 coordinates used in the latitude and longitude information
System is converted into GCJ02 coordinate systems or BD09 coordinate systems.
It is understood that above step S140 and S160 can be realized by an anti-geographical parsing interface, the interface
Better address can be parsed according to longitude and latitude, make the user do not need the geographic area for being concerned about target location and used understood
Analysis service.Judge that the geographic area of target location, coordinate system are converted and the calling of anti-geographical analysis service is all encapsulated in this and connects
The component internal of mouth.
