Reverse Geo-Coding You can now use latitude and longitude points to determine an address, city, province/state,

or country using new methods available from the

net.rim.device.api.lbs.Locator class. The class provides

Landmark[] reverseGeocode(Coordinates coord, int searchType) and

Landmark[] reverseGeocode(int latitude, int longitude, int searchType)

Location Picker API The Location Picker API, contained in the net.rim.device.api.lbs.picker package,

permits applications to invoke the LocationPicker to display a graphical list for a user to

select a location from. The list of facilities is configurable and might include the following:

• "My current location..." (GPS): If the BlackBerry device supports GPS, or if cell tower

triangulation is available, then the user's current location may be selected.

• "Find on a map..." (LBS): A user can search, pan, rotate and zoom the map to select a

location. Developers can mark predefined locations on the map. If GPS is supported then

the user’s current location may also be shown on the map. The user will have access to

their favorites and recent locations within the LBS application.

• "Recently selected..." (Previously selected locations): The LocationPicker stores 10

recent selections by a user, which may be used by all applications.

• "Application suggestions..." (predefined locations): You may provide predefined locations

in the list.

• "Using Google Maps™" (Registered location providers): Applications such as Google

Mapscan register as location providers to provide alternative resources for users to select

a location.

• "Enter a location..." (Manual entry): A user may enter an address / location via the

keyboard.
