摘要
震害专题图是震害研究和分析结果的一种直观表示方式，它由基本底图和专题叠加要素组成，基本底图内容的选择及其与专题叠加要素的配置将影响专题图的视觉感受和信息传输效果。本文在分析现有专题制图方法的基础上，提出了基于影像图的专题制图思想，详细讨论了其特点、技术指标和具体制图的实施问题，并给出了应用该方法制作震害专题图的一些情况。
Thematic map for seismic hazards is one of the results representations of seismic hazards research and analysis. It consists of the base map and thematic elements. The contents selection of the base map and its match with the thematic elements will affect on the visual sense responses and cartographic communications of thematic map. Based on the analysis of existing methods of thematic cartography, this paper puts forward the concept of photomap-based thematic cartography, and discusses its characteristics, technical aspects and implementations. The application to the thematic cartography for seicmic hazards is also given.
