We present a method for representing the 3D surfaces using the verbal representation, which human beings use for representation of topography. This method has advantages for representing relation of mountains and valleys. And the verbal representation gives human beings a concept of shapes through a small amount of information which is represented by symbols. It is expected that the verbalizing of the shape will make it possible to represent a shape features which is hard to be represented by contour lines. That is why the verbalizing is one of symbolizing methods of the shape. Therefore, an intelligent processing, such as inference, abstraction and so on, is executed on a computer.
In this paper, the words used for a topographical representation in the cartography are discussed. Next, the words used for the verbal representation are defined in 3D space. And the method is applied to a topographic map for representing a feature of the topography in a different way from the contour lines. Finally, we present a representing method of cartographic information data using the verbal representation.
