In this paper, the author examines whether map users can locate their residences on a base hazard map or on a city planning map. This study aims to clarify the relation between base map reading and the cartographic representation of hazard maps. Thirty residents of Nagoya City and fourteen residents of Nissin City participated in map-reading tasks. I examined the manner in which subjects, who were unable to locate their residences, made mistakes in interpreting a hazard-map representation.
It was observed that the subjects found it difficult to identify the location of their residences; in addition, only a few landmarks were depicted, and each landmark was represented on a similar-looking quadrangle on the hazard map. Repeated cartographic notation also made it difficult for subjects to locate their own residence. Parts were incorporated in the cartographic representation of the hazard map. There appears to be scope for further improvement in cartographic representation so as to enable easy interpretation.
