Developers can power apps to generate location queries without the need for GPS.
Developers can avail the service of Blackberry’s newly launched ‘Locate Service’ feature that allows applications to ask location based queries without the need for a GPS connection. To put it in simple words: the ‘Locate Service’ can help users to get a quick location fix using information from a nearby cell tower.
“Users can be indoors with no GPS coverage, but your app will still be able to guide them to restaurants or points of interest (POI) around them. Although the accuracy of the fixes obtained from the Geolocation service may not always be as high as with GPS, it has use cases for apps that require highly accurate GPS fixes as well as apps that do not. Apps that require high accuracy can use this service to quickly show the user an approximate location while it waits for a more accurate location fix using GPS. This can offer a huge user experience improvement. For applications that do not require high accuracy, this service can be leveraged as a simple yet effective mechanism to provide location information.”
The ‘Locate Service’ can be used to enhance the phone’s built-in GPS or completely replace it when a GPS signal is unavailable. The service will include a set of a components that “integrate seamlessly” with the Blackberry Maps, Contacts and the GPS.
Currently, there are no applications that actually takes advantage of the new service, but the tools are free for developers, so we can expect a few of them to pop out pretty soon.
