For a special fold stratum, besides the identification through fold plane distribution data, the judgment can be carried out through the form of a section stratum line, if a plurality of Z values exist on the fold stratum line on the section in the vertical direction, such as horizontal folds and the like, the layer construction is realized by using a local three-dimensional interpolation mode.
S4 floor crossing processing
