Abstract

An improved method and system for specifying physical locations when using applications run on navigation systems or other computer platforms that provide navigation- or map-related functions. When requesting a navigation- or map-related function from such an application, a user specifies a physical location using a keyword instead of specifying the physical location conventionally, such as by street address. A keyword database relates keywords to physical locations. The application uses the keyword database, or a copy thereof, to find data indicating the physical location associated with the keyword specified by the user. Preferably, physical locations are defined in the keyword database in terms of data in a corresponding geographic database. The application then performs the requested navigation- or map-related function using the data indicating the physical location associated with the keyword. The keyword database is built using input from users. An on-line system is provided that users can access to associate keywords with physical locations. A user accessing the on-line system is presented with a map from which a physical location can be selected. A keyword, which may be selected by the user, is associated with the selected physical location. The keyword is stored in the keyword database along with data indicating the associated physical location.

Claims

1. A method whereby users can register keywords that are associated with physical locations comprising:

providing a server on a computer network wherein said server is accessible by a first user; and

providing a program on said server that allows the first user to register keywords wherein registering includes;

accepting an identification by the first user of a specific map location;

associating the specific map location identified by the first user with a unique keyword specified by the first user;

accepting a user-specified instruction to facilitate routing to the specific map location from the first user;

associating the instruction with the unique keyword; and

storing said unique keyword and said instruction in a keyword database along with data from which said specific map location associated therewith can be determined, wherein said unique keyword is thereafter used by a second user to indicate said specific map location and said instruction is provided to the second user.

2. The method of claim 1 wherein said registering further comprises:

accepting a street address from the first user; and

geo-coding the street address to said specific map location.

3. The method of claim 1 wherein said registering further comprises:

presenting the first user with a list of subject matter categories when allowing said first user to identify a specific map location;

accepting a response to the presentation of the list of categories; and

storing data with said keyword indicating the response.

4. The method of claim 3 wherein said list of subject matter categories includes a hierarchy of categories.

5. A method of facilitating specification of locations by end users for obtaining navigation-related or map-related features, the method comprising the steps of:

with an on-line keyword program accessible to a first end user in a geographic region, accepting keyword registration requests from the first end user to register keywords, wherein each keyword is an alphanumeric word, string, or phrase, and further wherein the on-line keyword registration program is also operable to allow the first end user registering a keyword to associate a physical location in the geographic region and a user-provided instruction to facilitate routing to the physical location with the keyword;

maintaining a keyword database that associates the keywords with data indicating the respective physical locations and instructions associated therewith by the first end user; and

making the keyword database accessible on-line so that a second end user in the geographic region can use keywords registered by the first end user to specify locations in the geographic region and to receive the associated instruction.

6. The method of claim 5 wherein said on-line keyword program allows the first end user to define a relationship between multiple keywords and wherein said keyword database includes data indicating said relationship.

7. The method of claim 5 wherein said physical location refers to a road segment represented by a data record in a geographic database.

8. The method of claim 5 wherein said physical location refers to a location along a road segment represented by a data record in a geographic database.

9. The method of claim 5 wherein said physical location refers to a location along a side of a road segment represented by a data record in a geographic database.

10. The method of claim 5 wherein at least some of said keywords have a subject matter category is associated therewith.

11. The method of claim 10 wherein said subject matter category includes a user-defined category.

12. The method of claim 5 wherein the user-provided instruction includes delivery instructions for the physical location.

13. The method of claim 5 wherein at least some of said keywords are associated with data indicating multiple locations defined with respect to a geographic database.

14. The method of claim 5 wherein at least some of said keywords are temporary keywords that expire after a period of time.

15. The method of claim 5 wherein said keyword database stores data indicating physical locations with respect to geographic databases from multiple map vendors.

16. The method of claim 5 wherein said keyword database stores said physical locations with respect to multiple releases of a geographic database.

17. The method of claim 5 wherein said on-line keyword program allows the first end user to password-protect a keyword whereby access to the data indicating the physical location defined with respect to a geographic database associated with the keyword which is password-protected is limited to a person presenting the password.

18. A method of facilitating specification of locations by end users for obtaining navigation-related or map-related features, the method comprising the steps of:

providing an on-line keyword registration program accessible to a first end user in a geographic region, wherein the on-line keyword registration program is operable to accept from the first end user a specification of a keyword and an association of the keyword with a physical location in the geographic region and a user-provided instruction to facilitate routing to the physical location, wherein each keyword comprises a user-defined alphanumeric word, string, or phrase;

maintaining an on-line database that relates the physical location and the instruction specified by the first end user with the keyword specified by the first end user; and

providing navigation-related or map-related features with an application on a computer platform, wherein the application is operable to accept a request for a navigation-related or map-related function from a second end user, wherein the navigation-related or map-related function is requested using a keyword for specifying a physical location, and wherein the instruction is provided to the second end user after accepting the keyword.

19. The method of claim 18 wherein the application uses the keyword for a destination to which a route is determined.

20. The method of claim 18 wherein the user-provided instruction includes delivery instructions for the physical location.
