面向共享的地图符号可用性指标构建研究

Research on Shared-Oriented Map Symbol Usability Metrics Construction

首先依据可用性概念提出了地图符号的可用性,并从有效性、效率、满意度三个方面明确了地图符号可用性的评价内容。而后总结了六种专题制图方法和视觉变量的关联关系,在此基础上构建了面向共享的地图符号可用性指标,并将其应用在不同的专题地图制图任务和地图符号共享过程中。应用表明,文章构建的地图符号可用性指标,充分遵循评价指标的构建原则,内容全面、层次清晰,能够满足丰富的地图制图需求,为提高地图符号可用性提供了较好的依据和指导意义,进而为研究地图符号共享方法、拓展地图符号共享深度奠定基础。

Firstly,according to the concept of usability,this paper puts forward the usability of map symbol,and defines the evaluation content of map symbol usability from three aspects:effectiveness,efficiency and satisfaction.Then it summarizes the relationship between six thematic mapping methods and visual variables,on this basis,constructs the shared-oriented map symbol usability metrics,and applies it to different thematic map mapping tasks and the process of map symbol sharing.The application shows that the usability metrics of map symbol constructed in this paper fully follows the construction principle of evaluation metrics,has comprehensive content and clear level,can meet the rich needs of map mapping,provides good basis and guiding significance for improving the usability of map symbol,and then lays a foundation for studying the methods of map symbol sharing and expanding the depth of map symbol sharing.
