Abstract

A geographic information display control system displays objective geographic information using geographic data stored in a plurality of databases. A plurality of geographic data acquiring units instruct acquiring conditions, including a job script generated from a job selection, for acquiring the geographic data stored in the plurality of databases, and a processing request receiver determines, based on an attribute of the geographic data necessary for displaying the objective geographic information, which geographic data acquiring processor among the plurality of geographic data acquiring processors is requested to execute processing. As a result, a user can obtain required geographic data without knowledge of where the desired geographic data is or without being aware of where the knowledge is prepared.

Claims

a plurality of geographic data acquiring processors to define acquiring conditions, including the job script, to acquire the geographic data stored in said plurality of geographic data storage units; and

a processing request receiver to receive attribute information of geographic data requested from said geographic display controller, and to determine which geographic data acquiring processor among said plurality of geographic data acquiring processors is requested to execute processing, wherein

said geographic data display controller captures geographic data from said geographic data storage units based on an acquiring condition from said geographic data acquiring processor.

2. A geographic information display control system according to claim 1, wherein

said geographic data includes map data and image data, and

said acquiring conditions include information of which geographic data storage unit among said plurality of geographic data storage units the geographic data requested from said geographic data display controller is captured from, and

said attribute information includes a kind and a district of the geographic data requested from said geographic data display controller, and

said processing request receiver determines a geographic data acquiring processor to be requested to execute processing based on a capability of acquiring the geographic data from said plurality of geographic storage units.

3. A geographic information display control system according to claim 1 wherein

said geographic data display controller, said processing request receiver and said plurality of geographic data acquiring processors are constructed of programs stored in a memory medium.

7. A geographic information display control system according to claim 1 wherein the job selecting input device comprises a job selecting screen.

8. A geographic information display control system according to claim 7 and further including a job element table to be compared to said job script.

9. A geographic information display control system according to claim 8 wherein said job script is rewritten to processing combinations of an aerial photograph acquiring part, a contour map acquiring part, a river map acquiring part, and a house map acquiring part corresponding to combinations of element data of a drawing for the selected job.

10. A geographic information display control system according to claim 7 wherein said job script is rewritten to processing combinations of an aerial photograph acquiring part, a contour map acquiring part, a river map acquiring part, and a house map acquiring part corresponding to combinations of element data of a drawing for the selected job.

11. A geographic information display control system according to claim 1 and further including a job element table to be compared to said job script.

12. A geographic information display control system according to claim 11 wherein said job script is rewritten to processing combinations of an aerial photograph acquiring part, a contour map acquiring part, a river map acquiring part, and a house map acquiring part corresponding to combinations of element data of a drawing for the selected job.

13. A geographic information display control system according to claim 1 wherein said job script is rewritten to processing combinations of an aerial photograph acquiring part, a contour map acquiring part, a river map acquiring part, and a house map acquiring part corresponding to combinations of element data of a drawing for the selected job.

4. A geographic information display control system comprising:

a geographic data display;

a job selecting input device providing a job selection input;

a plurality of geographical data storage units storing geographic data;

a geographic data display controller receiving the job selection input to generate a job script and to capture the geographic data stored in said geographic data storage units in order to display the geographic data;

a plurality of first knowledge processors to obtain and instruct acquiring conditions through knowledge processing, said acquiring conditions including from which geographic data storage unit among said plurality of geographic data storage units geographic data requested in said geographic data display controller is acquired; and

a second knowledge processor to receive attribute information, including a kind and a district of the geographic data requested from said geographic data display controller, and determining, based on capability of acquiring geographic data from said plurality of geographic data storage unit through knowledge processing, which first knowledge processor among said plurality of first knowledge processors is requested to execute processing, wherein said geographic data display controller captures geographic data from said geographic data based on the acquiring condition obtained from said first knowledge processor.

5. A geographic information display control system comprising:

a geographic data display;

a job selecting input device providing a job selection input;

a plurality of geographical data storage units storing geographic data including map data and image data;

a geographic data display controller receiving the job selection input to generate a job script and to capture the geographic data stored in said geographic data storage units in order to display the geographic data;

a plurality of first knowledge processors to obtain acquiring conditions for acquiring the geographic data stored in said plurality of geographic data storing means;

a plurality of knowledge storage units to store attribute data for obtaining said geographic data acquiring conditions, one of said plurality of knowledge storing units being provided for each of said first knowledge processors; and

a second knowledge processor to receive attributes of the geographic data requested from said geographic data display controller, and determining, based on contents of the attribute data owned by said plurality of knowledge storage devices through knowledge processing, which first knowledge processor among said plurality of first knowledge processors is requested to execute processing, wherein

said geographic data display controller captures geographic data from said geographic data storage devices based on the acquiring condition obtained from said first knowledge processors.

6. A knowledge processing system for capturing geographic data stored in a plurality of geographic databases storing the geographic data including map data and image data and displaying the geographic data, which comprises:

a display;

a job selecting input device providing a job selection input;

a plurality of first knowledge processors to obtain acquiring conditions, including a job script based on the job selection input, to acquire requested geographic data required to be displayed on said display;

a plurality of knowledge storage units to store attribute data for obtaining said geographic data acquiring conditions, one of said plurality of knowledge storage units being provided for each of said first knowledge processors; and

a second knowledge processor to receive said attribute information of the requested geographic data, and determining through knowledge processing which first knowledge processor among said plurality of first knowledge processors is requested to execute processing.

14. A geographic information display control system according to claim 6 wherein the job selecting input device comprises a job selecting screen.
