This paper presents a method for concept formation of the surfaces of a two-dimensional multimodal function. We use the concepts 'TOP', 'SIDE' and 'BOTTOM' of a mountain as basic concepts for representation of those surfaces. These basic concepts for each point on surfaces are defined by 'IF-THEN' rules. The concepts formation of the surfaces are made based on those basic concepts and the results can be compared with concepts of the surfaces formed by human subjects. And then the similarity between them can be confirmed. The proposed method is useful in making a machine-oriented concept formation of surfaces such as topographic maps.
