This paper aims at clarifying icon-specific universal functions that are different from those of general map symbols by focusing on the subjective environmental expression of an act of environmental mapmaking. It is the question about the relationship between symbol's universality and individual places and tries to draw a focus on the value of symbols in environmental diversity.
The paper first sheds light on the origin of ‘Global Icons’ established by ‘Green Map’ as a method of analysis. Secondly, how those icons have been applied and expressed in specific areas is analyzed with the use of Green Maps throughout the world. Further, the method of icon application derived from this is verified through a case study of Green Mapmaking by elementary-school pupils in Hiroshima city.
In general, printed environmental maps are more explicit and exposed to the general public than a map posted on a website. Therefore it is believed that the content requires more objectivity. However, the global icons of the Green Map System are not necessarily quantitative.Quite a few icons are related to the character of places other than institutions. Some of such particular kinds of icons are being used rather frequently, which leads to interregional differences in icon application. This flexibility in the use of icons is connected to the natural environment of each region and the identity of its historical environment. Therefore, it can be considered that the versatility of icons depends not on the objectivity of the content but on the possibility of a different interpretation. Or more specifically, as is clear in children's icon application, it can be said that the latitude that allows the creation of a physical sense of appropriateness for the place is a prerequisite for a versatile use in icon application. After all, a sense of fitness which means our attachment towards certain places (KANSEI with historical body) is expressed through icons.
