Conceptual framework and practice of scene-based electronic map design
With the enrichment of spatial data elements and the refinement of scene difference granularity,homogeneous elec-tronic map products seriously affect the effect of spatial data aided decision-making.This paper proposes a conceptual frame-work for scene-based electronic map design,clarifies the definition and classification rules of application scene,determines four categories:application theme,objective environment,target user and mapping content,and summarizes the inherent require-ments of differentiated scenes for electronic maps.According to the above requirements,this paper proposes a scene-based electronic map design method,which completes the electronic map design through specific design means such as scene-sugges-ted symbol system construction and semantic-driven symbol combination expression.List three demand cases,the method of this paper is verified from the whole process of scene extraction,data organization and electronic map product design.The cog-nitive experiment shows that the scene-based electronic map designed based on the method of this paper is effective in visual processing,visual search and cognitive burden,and the expected consistency of cognitive effect,which provides a theoretical basis and practical path for scene-based electronic map design.
