基于地理信息的疫情可视化设计探讨——以《重庆市新型冠状病毒肺炎疫情地图》可视化设计为例

Visualized Epidemic Design Based on Geographic Information:Taking the Visualized Design of the Epidemic Map of COVID-19 in Chongqing as an Example

通过对新型冠状病毒肺炎疫情信息和数据的分析,探讨地理信息在疫情可视化设计中的方法及其艺术与社会价值。运用可视化、地图学的相关理论,辅以案例分析与实践性研究。从地理信息的位置、数量、关系等角度出发,聚合疫情信息和数据,借鉴信息可视化的方法,构建视觉语言的颜色、尺寸、形态等视觉化变量,完成对疫情地图的设计创作。将地理信息作为信息的模型与维度,探究可视化设计,提出疫情可视化设计的具体方法。疫情地图提高了时间与空间的信息精度,增强了用户的理解,可以为疫情区域防控决策提供一定的参考和支持。

Based on the analysis of the epidemic information and data of COVID-19,the method of geographic information applied in the visualized epidemic design and its artistic and social value are discussed.Theories relevant to visualization and cartography are supplemented by case studies and practical researches.The visual variables of visual language like color,size and form are constructed to complete the design and production of the epidemic map from the perspective of geographic information including location,quantity and relationship,combined with epidemic information and data,and with reference to information visualization.The geographic information is taken as the model and dimension of information to explore the visualized design and propose the specific methods for visualized epidemic design.The epidemic map improves the accuracy of time and space information,increases users’comprehension and provides a certain reference and support for the prevention and control decision in the epidemic area.
