Ground body classification system and ground body classification method

摘要

The problem of the present invention is to solve the problems of the prior art, that is, without the judgment of a person such as an expert. It is to provide a technology that can objectively and quantitatively classify the earth. A terrain classification system according to the present invention is a system that divides a target range into two or more terrestrial bodies based on three-dimensional coordinates of a plurality of measurement points, and includes a principal component analysis unit and a clustering unit. It is. The clustering means creates a scatter diagram of measurement point fluctuations in a planar coordinate system having the first principal component as the first axis and the second principal component as the second axis, and performs clustering to classify into two or more clusters. Then, based on the divided clusters, the terrestrial division of the target range is performed. [Selection] Figure 1
