A Study on Design of Hazard Maps

- Flood and Sediment-related Disaster Hazard Maps in Municipalities, Hyogo Prefecture-

Abstract

Hazard maps are useful information for residents to imagine damage and protect their lives and property. In this study, the map side of the hazard map was organized and analyzed from the viewpoint of design, and its features and problems were clarified. We classified flood and landslide hazard maps for Hyogo prefecture from a design perspective. For "representation", items were set and quantified based on Bertin's visual variables. Regarding the contents of the hazard map corresponding to the "plan", items were set and quantified based on national standards, and the hazard maps were classified into four types. As a result of the analysis, the proportions that meet the national standards were also different. As a whole, it was found that the awareness of map representation was low.
