Abstract Visual expression is increasingly used in historical research due to its intuitiveness and distinctness. However, most of the common research contents focus on the spatial concept, but lack the visualization analysis of the attribute characteristics of the research elements. In order to achieve this goal, based on a case study of the coastal military defense system in Ming Dynasty, the Geographic Information System (GIS) platform was adopted to reconstruct the historical map and its spatial data were extracted. On this foundation, the attribute characteristics of the military settlements, accessibility, was quantified by constructing a hierarchy evaluation model, and then the results were projected into the spatial geographic coordinates to realize the visualization of the accessibility of the military settlements in Ming Dynasty. The results showed that the combined method of quantification and visualization not only enabled more comprehensive and intuitive display of historical information, but also promoted data extraction and correlation analysis, creating a possibly for more in-depth future research.
