Filed:

Sep 2, 1999

Appl. No.:

09/388661

Inventors:

Lawrence M. Kaplan - Northbrook IL
John L. Hanson - Citrus Heights CA

Assignee:

Navigation Technologies Corp. - Chicago IL

International Classification:

G06F16500

US Classification:

701209, 701204, 340988

Abstract:

A navigation system includes a feature that allows a user to specify a type of point of interest at which the user wishes to make an intermediate stop while on route to a final destination. The feature identifies for the user one point of interest of the specified type at which an intermediate stop can be made while on route to the final destination, wherein a route to the final destination that includes an intermediate stop at the one point of interest takes less time than routes to the final destination that make an intermediate stop at other points of interest of the specified type.

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.

Filed:

Apr 11, 1997

Appl. No.:

8/834652

Inventors:

John L. Hanson - Des Plaines IL
Robert H. Shotz - Alpharetta GA

Assignee:

Navigation Technologies Corp. - Rosemont IL

International Classification:

G01S 502
G01C 2100

US Classification:

701208

Abstract:

A system and method for acquiring differentially corrected GPS data for forming a digital database of road geometry in a geographic region. A vehicle having a GPS receiver and a DGPS demodulator located therein is driven on roadways in the geographic region. The GPS receiver receives standard GPS signals and the DGPS demodulator receives DGPS signals which are used to correct the standard GPS signals. The corrected GPS signals are stored where they can be processed to create a digital database. Alternately a GPS receiver is positioned at a stationary location along with a portable DGPS demodulator. A vehicle having a GPS receiver located therein is driven on roadways in the geographic region. The GPS receiver at the stationary location is continuously operated and the DGPS demodulator is operated once to receive a DGPS signal. The DGPS demodulator can then be moved to another geographic region.
