Information Update

MSP 2.0 also provides a reverse path for information low from client to server. This allows a mobile application to deliver updated information about the real world to the NSP. The basic principle of computing navigation services is to use a detailed model of the things in the real world, such as roads, towns, lakes, signs, hotels, and other elements in computations that answer questions about or provide guidance for mobile activities in the real world. The matching or coherence between the modeled and real world largely determines the perceived quality of the services. The capability to enhance coherence through feedback from the real world is extremely valuable.

Information update

One of the persistent difficulties in supplying meaningful and useful updates has been the lack of a common underlying conceptual model on which such communications could be based. The details of a common model are not very important as long as the meaning of the elements is well understood by clients and servers alike.
