Solution Overview
Problem
Current thematic map preparation methods are labor-intensive, subjective, and lack automation, making it difficult to efficiently manage and compare multi-source heterogeneous data, leading to inconsistencies and security risks in data representation and update.
Innovation Solution
A method and apparatus for preparing thematic maps by generating a map style master with metadata, processing original input data to acquire attribute color identifications, and updating the map style master to create a thematic map, enabling the fusion of multi-source heterogeneous data for automated and standardized mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual methods are used to prepare thematic maps, then flexibility and customization are improved, but labor intensity increases and automation is reduced
Solution Approach 1:
The thematic map preparation process is segmented into distinct modules: data acquisition module, data processing module, map style master generation module, and map rendering module. Each module handles specific tasks independently, enabling automated processing while maintaining flexibility through modular configuration.
Solution Approach 2:
The system performs preliminary actions by pre-generating map style masters with standardized templates, color schemes, and layout configurations before actual map production. This preparation work is done once and reused across multiple mapping tasks, reducing repetitive manual labor while maintaining consistency.
2Adaptability or versatility
If manual methods are used to prepare thematic maps, then customization capability is improved, but consistency and standardization deteriorate
Solution Approach 1:
The system uses parameter-based control where map style masters define standardized parameters for colors, labels, symbols, and layouts. Users can customize maps by modifying parameters within predefined ranges and options, ensuring consistency is maintained through parameter constraints while allowing necessary customization.
Solution Approach 2:
The map style master serves multiple functions: it standardizes map production, enables batch processing, maintains consistency across different maps, and allows customization through configurable parameters. This universal template approach resolves the contradiction between standardization and customization.
3Quantity of substance
If data from multiple sources are integrated manually, then data comprehensiveness is improved, but time consumption and labor increase
Solution Approach 1:
The system merges multiple data sources by integrating various data formats and structures into a unified processing framework. The data processing module automatically combines geographical data, attribute data, and spatial information from multiple sources, achieving comprehensive data integration through automated merging operations.
Solution Approach 2:
The system uses copying mechanisms to replicate standardized processing procedures across different data sources. Once a data processing workflow is established, it can be copied and applied to multiple datasets automatically, reducing time consumption while maintaining comprehensive data integration.
4Productivity
If automated data processing is implemented, then productivity is improved, but data security risks may increase
Solution Approach 1:
The system introduces an intermediary layer between automated processing and raw data. The map style master acts as a mediator that controls and regulates data processing operations, ensuring that automated processes follow predefined security protocols and access controls while maintaining high productivity.
