Computers today are more mobile than ever. From small laptops to Tablet PCs, many computers can go wherever the user wants to go. Programs that take advantage of the computer's mobility can add significant value to people's lives. For example, a program that can find nearby restaurants and provide driving directions would seem to be a natural fit for a portable computer. But while the technology to determine the user's current location is common and affordable, building solutions on this technology can be a daunting task.
To create a location-aware program, you might need to overcome a variety of issues, including:
- Global positioning system (GPS) devices that use virtual COM ports, which provide access for only one program at a time.
- Understanding and programming for protocols, such as the National Marine Electronics Association (NMEA) specification, as well as proprietary vendor extensions.
- Being confined to programming for known, vertical hardware solutions.
- Implementing logic to handle transitions between various location providers, such as GPS receivers, connected networks, cellular telephone networks, the Internet, and user settings.
This documentation describes the Windows Location application programming interface (API). The Location API helps to simplify location-aware programming by providing a standard way to retrieve data about user location and standardizing formats for location data reports. The Location API automatically handles transitions between location data providers and always chooses the most accurate provider for the current situation.
Note Because information about a person's location can be sensitive data, Windows helps protect user privacy. For information about privacy protection, see Privacy and Security in the Sensor and Location Platform.
