DETERMINATION METHOD FOR POSITIONING SUBSOIL EXPLORATION, DETERMINATION DEVICE, SUBSOIL ESTIMATION METHOD AND SUBSOIL ESTIMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a determination method for positioning subsoil exploration, a determination device, a subsoil estimation method and a subsoil estimation device capable of not only quantitatively evaluating error but rationally determining additional positions and the number for exploration therefor.;SOLUTION: A determination method for positioning subsoil exploration comprises: steps S1 and S2 not only estimating space distribution of subsoil property in a target area through a kriging method using subsoil data acquired in previous explore but calculating space distribution of the estimated error; a step S3 calculating the space distribution of error between an estimation of subsoil property in acquisition positions of subsoil data used in the estimation using cross validation and the subsoil property estimated through the kriging method; a step 4 calculating the space distribution of error index on the basis of the estimated error calculated through the kriging method and the error calculated by the cross validation; and steps S5 and S6 determining additional positions for exploration on the basis of the space distribution of the calculated error index.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
