Abstract

A method of operation of a navigation system includes: preconstructing a multi-layered index based on a plurality of a spatially-aware identification for identifying location data points; selecting a first intersection based on the multi-layered index of the spatially-aware identification; and generating a primary route based on the first intersection for displaying on a device.

Description

technical field [0001] The present invention relates generally to navigation systems, and more particularly to navigation systems with map compression. Background technique [0002] Modern portable consumer and industrial electronics offer increasing levels of functionality to support modern life, including location-based information services. This is especially true for client devices such as navigation systems, cell phones, portable digital assistants, and multifunction devices. [0003] As users adopt location-based service devices, new and old uses begin to take advantage of this new device space. There are many technical solutions to take advantage of this new device location opportunity. One existing approach is to use location information to provide navigation services, such as a Global Positioning Service (GPS) navigation system for mobile devices. The system can display map information, navigate and display a route between two points, and enable other services on...
