Abstract:
A system and method for switching a positioning device between using a first positioning technology and using a second positioning technology includes determining a location of the positioning device based on the first positioning technology, determining environment information corresponding to the location of the positioning device, and determining a location of a boundary where switching from the first positioning technology to the second positioning technology should occur. The method also includes switching from the first positioning technology to the second positioning technology prior to the positioning device crossing the boundary.
