Abstract

An integrated GIS system in which a 3D visualization system is integrated with a 2D GIS system using interfaces that map 2D components for 3D visualization and map 3D components for processing by the 2D GIS system. A 2D GIS system and a 3D visualization system are integrated through interfaces that provide for 3D visualization of 2.5D GIS data as well as interactive control of the 2D GIS system from 3D windows containing 3D renderings produced by the 3D visualization system. User selections made in a 3D window are mapped to 2D geo-location coordinates for to use by the 2D GIS system components. Changes made via the 3D window to 3D graphic indicia and/or metadata are used to modify GIS data in a GIS database, and the modified GIS data is used to update the 3D rendering to reflect the user changes.

Claims

1. A method of integrating a 3D visualization system with a 2D GIS system to provide an interactive 3D interface, the method comprising:

providing an interface between the 2D GIS system and the 3D visualization system;

providing, by the interface, GIS information received from the 2D GIS system to the 3D visualization system;

providing, by the interface, 3D rendering data from the 3D visualization system to the 2D GIS system;

producing, by the 2D GIS system, a display in a 3D window on a display device including 3D graphic indicia from the 3D rendering data and GIS information from the 2D GIS system, the 3D graphic indicia being displayed in a geospatial manner as a function of the GIS information; and

mapping, by the interface, user selections made in the 3D window to corresponding 2D geo-location coordinates for use by the 2D GIS system.

2. The method according to claim 1, further comprising:

using the 3D graphic indicia displayed on the display device to change the GIS information in the 2D GIS system.

3. The method according to claim 2 wherein using comprises:

modifying at least a portion of the 3D graphic indicia on the display device; and

modifying a corresponding portion of the GIS information in the 2D GIS system.

4. The method according to claim 2 wherein using comprises:

receiving a message indicating that at least a portion of the 3D graphic indicia has been changed, the message having change information relating to the change of the 3D graphic indicia; and

in response to receipt of the message, modifying the GIS information in the 2D GIS system based on the change information of the message.

5. The method according to claim 2 wherein the GIS information is changed substantially in real time as the 3D graphic indicia is modified.

6. The method according to claim 2 wherein changing the GIS information comprises at least one of changing existing information and adding additional information.

7. The method according to claim 1 wherein the 3D graphic indicia includes a three-dimensional visualization display of the GIS information.

8. The method according to claim 7 wherein using the 3D graphic indicia consists of utilizing an input device to select or add graphic objects to the three-dimensional visualization display.

9. The method according to claim 1 where the 3D graphic indicia includes a three-dimensional visualization of terrestrial features.

10. An integrated GIS system including an interactive 3D interface, the system comprising:

a client 2D GIS system;

a 3D visualization system; and

an interface between the 2D GIS system and the 3D visualization system, the interface configured to provide GIS information received from the 2D GIS system to the 3D visualization system and to provide 3D rendering data from the 3D visualization system to the 2D GIS system for display in a 3D window on a display device including 3D graphic indicia from the 3D rendering data and GIS information from the 2D GIS system, the 3D graphic indicia being displayed in a geospatial manner as a function of the GIS information, the interface further configured to map user selections made in the 3D window to corresponding 2D geo-location coordinates for use by the 2D GIS system.

11. The system according to claim 10, wherein the 2D GIS system is further configured to change the GIS information in the 2D GIS system in response to changes made to the 3D graphic indicia displayed on the display device.

12. The system according to claim 11, wherein the 2D GIS system is configured to modify a portion of the GIS data in the GIS database corresponding to a modified portion of the 3D graphic indicia.

13. The system according to claim 11, wherein the 2D GIS system is configured to receive a message indicating that at least a portion of the 3D graphic indicia has been changed, the message having change information relating to the change of the 3D graphic indicia, and in response to receipt of the message, to modify the GIS information in the 2D GIS system based on the change information of the message.

14. The system according to claim 11, wherein the 2D GIS system changes the GIS information substantially in real time as the 3D graphic indicia is modified.

15. The system according to claim 11, wherein the 2D GIS system is configured to change the GIS information by at least one of changing existing information and adding additional information.

16. The system according to claim 10, wherein the 3D graphic indicia includes a three-dimensional visualization display of the GIS information.

17. The system according to claim 16, further comprising an input device used to select or add graphic objects to the three-dimensional visualization display.

18. The system according to claim 10, where the 3D graphic indicia includes a three-dimensional visualization of terrestrial features.
