Abstract

A system and method for viewing and editing digital maps using a plugin data abstraction layer for different digital map formats. An embodiment of the present invention is generally related to systems for accessing, displaying, editing and using digital maps. The system includes a viewer application together with a data abstraction layer and a plurality of different data abstraction interfaces. The data abstraction layer can be used to allow different map formats to be parsed and viewed. This allows the system to receive data in any of a variety of different input map formats. The map can then be edited, viewed, displayed on a display screen, or output. The map can also be used to create or display a map in a universal display format that is independent of the original format.

Claims

1. A system for viewing and editing digital maps using a plugin data abstraction layer for different digital map formats, comprising:

a set of map data that corresponds to a digital map, and having a first map format associated therewith;

a data abstraction layer, that allows one or a plurality of data abstraction interfaces to be plugged into the layer, and that includes an interface for the first map format that allows the system to receive and display the map data;

a semantic definition file that converts map items into a plurality of semantically linked items;

a display device including a graphical window that is used to display the digital map in a universal display format together with the semantically linked items; and

a user interface that allows an operator to retrieve and display a digital map having the first map format into the system, wherein the system then uses the data abstraction interface and semantic definition file for that map format to receive and display the digital map on the display device in the universal display format.

2. The system of claim 1 wherein the first map format is Public Sector Information (PSI) format.

3. The system of claim 1 wherein the first map format is Geographic Data File (GDF) format and the second map format is Public Sector Information (PSI) format.

4. The system of claim 2 wherein the first format is PSI, and wherein the operator can further select that a level of the PSI map be displayed on the display device.

5. The system of claim 1 wherein the data abstraction layer allows a first and second data abstraction interfaces to be plugged into the layer, and that includes an interface for a second map format and allows the system to receive and display map data in the second map format.

6. The system of claim 5 wherein the data abstraction layer allows a plurality of data abstraction interfaces, in addition to the first and second data abstraction interfaces to be plugged into the layer, to support a plurality of different map formats.

7. A method for viewing and editing digital maps using a plugin data abstraction layer for different digital map formats, comprising the steps of:

providing a set of map data that corresponds to a digital map, and having a first map format associated therewith;

providing a data abstraction layer, that allows one or a plurality of data abstraction interfaces to be plugged into the layer, and that includes an interface for the first map format that allows the system to receive and display the map data;

providing a semantic definition file that converts map items into a plurality of semantically linked items;

displaying on a display device including a graphical window the digital map in a universal display format together with the semantically linked items; and

allowing an operator to retrieve and display a digital map having the first map format into the system, and using the data abstraction interface and semantic definition file for that map format to receive and display the digital map on the display device in the universal display format.

8. The method of claim 7 wherein the first map format is Public Sector Information (PSI) format.

9. The method of claim 7 wherein the first map format is Geographic Data File (GDF) format and the second map format is Public Sector Information (PSI) format.

10. The method of claim 8 wherein the first format is PSI, and wherein the operator can further select that a level of the PSI map be displayed on the display device.

11. The method of claim 7 wherein the data abstraction layer allows a first and second data abstraction interfaces to be plugged into the layer, and that includes an interface for a second map format and allows the system to receive and display map data in the second map format.

12. The method of claim 11 wherein the data abstraction layer allows a plurality of data abstraction interfaces, in addition to the first and second data abstraction interfaces to be plugged into the layer, to support a plurality of different map formats.
