Patent ID: 7801904

Claim:
A method of operation for a navigation system comprising: on a server, using a repository for geographic data, wherein the repository contains a plurality of pre-computed parcels of geographic data, wherein the geographic data in each of the parcels represent geographic features contained in a separate one of a plurality of geographic sub-areas into which a geographic region is divided, wherein the each of the parcels contains a plurality of data records that represent the road segments records, node records, name records and points of interest records located within the geographic sub-area corresponding to the parcel; on the server, receiving a request for a route from an origin to a destination; on the server, calculating a route from said origin to said destination; on the server, after said step of calculating the route, using the calculated route to identify the geographic sub-areas that are crossed by the calculated route; on the server, identifying the parcels that contain all the data records that represent the geographic features encompassed in the geographic sub-areas that the route passes through; transmitting data that represents the calculated route to an end user computing platform; transmitting all of the data records contained in the parcels that represent the geographic features encompassed in the geographic sub-areas the route passes through to the end user computing platform, wherein the data contained in the parcels includes data that is searchable for identifying points of interest located in the geographic sub-areas the route passes through; on the end user computing platform, storing the transmitted parcels in a memory associated with the end user computing platform; on the end user computing platform, after said step of storing the transmitted parcels in the memory, receiving a request for a point of interest based upon specified criteria that is located proximate the route; and on the end user computing platform, using data from the transmitted parcels that represent the geographic features encompassed in the geographic sub-areas that the route passes through to find said point of interest based upon said specified criteria that is located proximate the route without making a request to the server.
