METHODS AND SYSTEMS FOR UPDATING A DIGITAL MAP

摘要

A digital map update system includes a digital map update server in communication with each one of a plurality of remote client devices for providing data indicative of a set of one or more digital map incremental updates thereto for use by the client devices in incrementally updating respective existing digital maps of the devices. The system comprises two or more digital map update repositories, each update repository comprising data indicative of a plurality of digital map incremental updates for use in incrementally updating a client device, and each being in respect of a different digital map incremental update profile. In use, the digital map update server provides a set of one or more digital map incremental updates from a given one of the update repositories to a remote client device for use by the device in incrementally updating an existing digital map of the device in accordance with the update profile of the given update repository.
