    • A method for reverse geocoding location information obtained by a wireless communications device comprises determining the location information for a location, communicating the location information to a reverse geocoding server that reverse-geocodes the location information to generate location description data for a bounding region that geographically surrounds the location, receiving the location description data from the reverse geocoding server for the bounding region containing the location, and caching the location description data for the bounding region in a memory cache on the device. When the current location remains within one or more bounding regions cached on the device, location description data is fetched from the cache, thus improving application responsiveness. Only when the current location is no longer within the bounding region(s) does the device communicate a new request to the reverse geocoding server.
    • 用于对由无线通信设备获得的位置信息进行反向地理编码的方法包括确定位置的位置信息,将位置信息传送给逆向地理编码服务器,该反向地理编码服务器对位置信息进行反向地理编码,以生成地理环境的边界区域的位置描述数据 该位置,从用于包含该位置的边界区域的反向地理编码服务器接收位置描述数据,以及缓存该设备上的存储器高速缓存中的边界区域的位置描述数据。 当当前位置保持在设备上缓存的一个或多个边界区域内时,从高速缓存中取出位置描述数据,从而提高应用程序的响应能力。 只有当当前位置不再在边界区域内时,设备才会将新的请求传达给反向地理编码服务器。

    • A handheld electronic device, such as a GPS-enabled wireless communications device with an embedded camera, a GPS-enabled camera-phone or a GPS-enabled digital camera, determines whether ephemeris data needs to be obtained for geotagging digital photos taken with the device. By monitoring user activity with respect to the camera, such as activation of the camera, the device can begin pre-acquisition of a GPS position fix by obtaining needed ephemeris data before the photograph is actually taken. This GPS pre-acquisition improves the likelihood that a position fix (GPS lock) is achieved by the time the photo is taken (to enable immediate geotagging). Alternatively, the photo can be geotagged retroactively by appending the current location to the metadata tag associated with the digital photo. An optional acquisition status indicator can be displayed on a user interface of the device to indicate that a position fix is being obtained.
    • 诸如具有嵌入式相机的具有GPS功能的无线通信设备,支持GPS的相机电话或支持GPS的数码相机的手持电子设备确定是否需要获取星历数据以便将设备拍摄的数字照片进行地理标记 。 通过监视摄像机的用户活动,例如相机的启动,设备可以在实际拍摄照片之前获取所需的星历数据,开始预先获取GPS定位。 这种GPS预采集可以提高在拍摄照片时实现位置锁定(GPS锁定)(实现立即地理标记)的可能性。 或者,可以通过将当前位置附加到与数字照片相关联的元数据标签来追溯地进行地理标记。 可以在设备的用户界面上显示可选的采集状态指示符,以指示正在获得定位。
