<P>PROBLEM TO BE SOLVED: To provide a ground analysis method capable of visualizing geological feature and content states of groundwater and clay mineral, and performing the evaluation highly accurately, without undergoing classification into colors by human work. <P>SOLUTION: Measured data acquired by an electromagnetic search using aerial electromagnetic method undergoes various corrections and leveling. Then, a resistivity value is calculated for each measurement point, grid-form resistivity data is generated for each frequency after interpolating process, and a three-dimensional resistivity model is created by combining the grid-form resistivity data and data of a numerical altitude model. Then, grid-form resistivity data regarding an arbitrary vertical cross section is generated, to which a differential analysis for the resistivity and further, a Laplacian analysis are performed, thereby converting the resistivity value into the evaluated value for output. <P>COPYRIGHT: (C)2012,JPO&INPIT |
