Abstract

A system and method are disclosed for collecting data that relate addresses to map-referenced locations. A fleet of delivery trucks delivers items to locations throughout a geographic region. Each item to be delivered includes a tracking code. An electronic code reader device is used to record the tracking code of an item when the item is being delivered. A position determining device, such as a GPS unit, is used to determine a geographic position associated with the delivery of each item. Data indicating the tracking code of an item and the corresponding geographic position associated with the delivery are stored. Then, using data that indicate an address associated with each tracking code, each address is associated with a geographic position. This information is used to revise a geographic database, e.g., to relate addresses to map-referenced locations.

Claims

1. A method of collecting data for a geographic database comprising the steps of:

collecting data while making deliveries of items to locations of addresses in a geographic area, wherein said step of collecting data includes;

making deliveries of the items to the locations of addresses in the geographic area;

using positioning equipment to determine a geographic position associated with each delivery; and

storing data by which the geographic position associated with each delivery is related to an address associated with the item being delivered; and

revising the geographic database based on a relationship between the geographic positions associated with the deliveries and the addresses associated with the items being delivered.

2. The method of claim 1 further comprising:

using a portable code recording device to record a code associated with an item being delivered, wherein the code associated with an item is related to the address to which the item is to be delivered; and

using the code to relate the address to which an item is delivered to the geographic position associated with the delivery.

3. The method of claim 2 wherein the code is affixed to the item being delivered.

4. The method of claim 1 wherein the step of making deliveries is performed by a delivery company and the step of revising the geographic database is performed by a geographic database developer.

5. The method of claim 1 wherein the step of making deliveries is performed using delivery trucks.

6. The method of claim 1 wherein the step of revising includes updating address ranges associated with road segments represented in the geographic database.

7. The method of claim 1 wherein the step of revising includes associating geographic coordinates with addresses to provide improved estimates of address locations.

8. The method of claim 1 further comprising:

prior to the step of revising, performing statistical analysis on data representing multiple deliveries of items to the same address.

9. A method of collecting data for a geographic database comprising the steps of:

collecting data while making deliveries of items to locations in a geographic area, wherein the locations are associated with identifying information, wherein said step of collecting data includes;

making deliveries of the items to the locations in the geographic area;

using positioning equipment to determine a geographic position associated with each delivery; and

storing data by which the geographic position associated with each delivery is related to the identifying information associated with the location to which the item is being delivered; and

revising the geographic database based on a relationship between the geographic positions associated with the deliveries and the identifying information associated with the locations to which the items are delivered.

10. The method of claim 9 wherein the identifying information includes at least one of vanity addresses, building or location names, business names, individual person names, facility names, and administrative names.

11. The method of claim 9 further comprising:

using a portable code recording device to record a code associated with an item being delivered, wherein the code associated with an item is related to the identifying information associated with the location to which the item is delivered; and

using the code to relate the identifying information associated with the location to which an item is delivered to the geographic position associated with the delivery.

12. The method of claim 11 wherein the code is affixed to the item being delivered.

13. The method of claim 9 wherein the step of making deliveries is performed by a delivery company and the step of revising the geographic database is performed by a geographic database developer.

14. The method of claim 9 wherein the positioning equipment is associated with a delivery truck used to make the deliveries.

15. The method of claim 9 wherein the step of revising includes associating geographic coordinates with the identifying information.

16. The method of claim 9 further comprising:

prior to the step of revising, performing statistical analysis on data representing multiple deliveries of items to the same location.

17. A method of collecting data for a geographic database comprising the steps of:

collecting data while making deliveries of items to locations of addresses in a geographic area, wherein said step of collecting data includes;

making deliveries of items to the locations of addresses in the geographic area;

using positioning equipment to determine a geographic position associated with each delivery; and

storing data by which the geographic position associated with each delivery is related to an address associated with the item being delivered; and

providing the collected data to a geographic database developer for revising the geographic database based on a relationship between the geographic positions associated with the deliveries and the addresses associated with the items being delivered.

18. A method of revising a geographic database comprising the steps of:

obtaining data collected by a delivery company, wherein the delivery company collects the data while making deliveries of items to locations of addresses in a geographic area, wherein the delivery company uses positioning equipment to determine a geographic position associated with each delivery and stores data by which the geographic position associated with each delivery is related to an address associated with the item being delivered; and

revising the geographic database based on a relationship between the geographic positions associated with the deliveries and the addresses associated with the items being delivered.

19. A method of revising a geographic database comprising the steps of:

obtaining data collected by a delivery company, wherein the delivery company collects the data while making deliveries of items to locations in a geographic area, wherein the delivery company uses positioning equipment to determine a geographic position associated with each delivery and stores data by which the geographic position associated with each delivery is related to identifying information associated with the item being delivered; and

revising the geographic database based on a relationship between the geographic positions associated with the deliveries and the identifying information associated with the items being delivered.

20. The method of claim 19 wherein the identifying information includes at least one of vanity addresses, building or location names, business names, individual person names, facility names, and administrative names.
