Abstract

A reporting program and system for updating a master copy of a geographic database is disclosed. According to the method and system, reports are obtained that relate to data contained in a geographic database. Satellite images of the geographic locations represented by the data in the reports are obtained. The satellite images are analyzed to confirm a need to make changes to the master copy of the geographic database based on the reports. After confirming the need to make the changes, the master copy of the geographic database is updated.

Claims

1. A method for updating a master copy of a geographic database comprising:

obtaining a report indicating an error in data that represent a geographic feature;

based on said report, obtaining a satellite image containing said geographic feature indicated in said report;

displaying the satellite image at a workstation;

while displaying the satellite image at a workstation, displaying said geographic feature as represented by data contained in the master copy of a geographic database at the workstation;

analyzing the satellite image to determine how to update the master copy of the geographic database;

updating the master copy of the geographic database; and

storing the master copy of the geographic database on a storage medium.

2. The method of claim 1 wherein further comprising:

forming a derived database product from said updated master copy of the geographic database.

3. The method of claim 1 wherein said report comprises feedback from an end user of the geographic database.

4. The method of claim 3 wherein said end user uses said geographic database with a navigation system.

5. The method of claim 3 wherein said end user uses said geographic database with an online navigation-related service.

6. The method of claim 1 wherein said report is obtained via telephone.

7. The method of claim 1 wherein said report is obtained via the Internet.

8. The method of claim 1 further comprising:

indicating a position on the satellite image being displayed wherein said position corresponds to a location of said geographic feature indicated in said report.

9. The method of claim 1 further comprising:

overlaying said geographic feature as represented by data contained in the master copy of a geographic database over the satellite image being displayed at the workstation.

10. The method of claim 1 wherein said report relates to a road.

11. A method of updating a master copy of a geographic database comprising:

obtaining an indication of a perceived inaccuracy in data that represents a geographic feature;

identifying a satellite image containing said geographic feature of said indication;

indicating a position on the satellite image being displayed wherein said position corresponds to a location of said geographic feature;

comparing said geographic feature in said satellite image to data that represents said geographic feature;

if said data inaccurately represents said geographic feature in said satellite image, confirming said inaccuracy in data that represents said geographic feature; and

updating the master copy of the geographic database to provide data that accurately represents said geographic feature, wherein the updated master copy of the geographic database is stored on a storage medium.

12. The method of claim 11 further comprising:

if said data inaccurately represents said geographic feature, determining appropriate changes to make to the master copy of the geographic database to correct said inaccuracy.

13. The method of claim 11 wherein said step of obtaining said indication comprising obtaining feedback from an end user of the geographic database.

14. The method of claim 11 further comprising:

after identifying said satellite image, displaying said satellite image at a workstation of a geographic database developer.

15. The method of claim 11 wherein said report relates to a road.

16. The method of claim 11 wherein said step indicating the position on the satellite image comprises displaying the position of said geographic feature of said indication at a center of the display of said workstation.

17. The method of claim 11 further comprising:

forming a derived database product using said updated master copy of the geographic database.

18. A method of updating a master copy of a geographic database comprising:

obtaining an indication of a perceived inaccuracy in data that represents a geographic feature;

identifying a satellite image containing geographic feature of said indication;

while displaying the satellite image at a workstation, displaying said geographic feature as represented by data contained in the master copy of a geographic database at the workstation;

comparing said geographic feature in said satellite image to data that represents said geographic feature;

if said data inaccurately represents said geographic feature in said satellite image, confirming said inaccuracy in data that represents said geographic feature; and

updating the master copy of the geographic database to provide data that accurately represents said geographic feature, wherein the updated master copy of the geographic database is stored on a storage medium.

19. A method for updating a master copy of a geographic database comprising:

obtaining a report indicating an error in data that represents a geographic feature;

based on said report, obtaining a satellite image of a region including said geographic feature;

displaying the satellite image satellite image at a workstation;

overlaying said geographic feature as represented by data contained in the master copy of the geographic database over the satellite image being displayed at the workstation;

analyzing the satellite image to determine how to update the master copy of the geographic database;

updating the master copy of the geographic database; and

storing the master copy of the geographic database on a storage medium.

20. The method of claim 19 further comprising:

forming a derived database product.
