Geographic database with detailed local data
First Claim
1. A geographic database system comprising:
- a representation of a main road network in a geographic region, including representations of roads of which said main road network is comprised;
representations of access points, wherein each of said access points corresponds to a location at which the main road network is accessible from locations away from the main road network, and wherein each of said access points is associated with a corresponding location reference code that indicates the location of the represented access point; and
representations of facilities that are physically located away from the main road network and access to which requires travel on paths other than said main road network, wherein each of said representations of facilities is associated with a corresponding location reference code that indicates the location of the represented facility, and further wherein each of said representations of facilities is associated with an indication of a path to an associated access point.

Abstract
A method is disclosed for representing locations in a geographic database in a manner that facilitates navigation and routing. A core map database includes data that represents public roads in a geographic region. Each of a plurality of location map databases includes data that represent facilities, such as businesses, stores, offices, or other places, that are physically located away from the public network and access to which requires travel on paths away from the public road network. Each of the facilities represented in the location map databases is assigned a location reference code that is associated with data from which a path connecting the facility and the public road network can be determined.

1. A geographic database system comprising:
-
a representation of a main road network in a geographic region, including representations of roads of which said main road network is comprised; representations of access points, wherein each of said access points corresponds to a location at which the main road network is accessible from locations away from the main road network, and wherein each of said access points is associated with a corresponding location reference code that indicates the location of the represented access point; and representations of facilities that are physically located away from the main road network and access to which requires travel on paths other than said main road network, wherein each of said representations of facilities is associated with a corresponding location reference code that indicates the location of the represented facility, and further wherein each of said representations of facilities is associated with an indication of a path to an associated access point. - View Dependent Claims (2, 3, 4)

5. A geographic database system comprising:
-
a core database that includes data that represents a public road network in a geographic region; and a plurality of location databases, each of which represents features located physically away from the public road network, wherein each feature represented in one of the location databases is represented by a location reference code, and wherein each location reference code is associated with data that indicates a way to access the feature from the public road network. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A database for geographic data comprising:
-
(i) representations of public roads in a geographic region; (ii) street address information associated with said representations of public roads; (iii) representations of facilities having street addresses along said public roads, but which are physically accessible via non-public roads; (iv) representations of said non-public roads; (v) data indicating locations along said public roads at which said non-public roads are accessible; and (vi) data associating said facilities with the non-public roads via which said facilities are accessible. - View Dependent Claims (14, 15)

16. A method for representing facilities located off a public road network comprising:
-
identifying geographic positions of facilities located off the public road network; identifying geographic positions of one or more points that define a path connecting each of said facilities to the public road network; assigning location reference codes to said geographic positions; and associating with each of said location reference codes data that defines a path that connects each geographic position assigned a location reference code and the public road network via one or more geographic positions to which geographic reference codes have been assigned. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method for determining a route to a desired destination at a facility comprising:
-
using a database that includes representations of facilities that are physically located away from a main road network and access to which requires travel other-than-on said main road network, upon determining one of said facilities as the desired destination, accessing data associated with said representation of said facility that indicates a path to the facility from an associated access point, wherein said access point corresponds to a location at which a main road network is accessible from locations away from the main road network; using a data representation of the main road network to calculate a route to the access point associated with the one of said facilities determined to be the desired destination; and combining the calculated route with the indicated path from the associated access point data to the one of said facilities determined to be the desired destination. - View Dependent Claims (29)

30. A method for calculating a route to a destination comprising:
-
receiving a specification of a desired destination; using the specification to search a location database for a potential destination that matches the specification; using a core database to calculate a route between an origin and an access point on a road network; and using the location database to determine a path between the access point and the potential destination, wherein the path is determined by data stored in the location database that indicates paths connecting points to which location reference codes have been assigned back to the road network via one or more other points. - View Dependent Claims (31)
