The point of the plane and the corresponding field source information constitutes a three-dimensional surface. Trough and peak characteristic lines are important factors which control surface morphology. Extraction of surface-trough and surface-peak characteristic lines contributes to automatic extraction and recognition of field source. In this paper, the author shows solving process of two characteristic lines and analyzes its corresponding significance of geology and geophysics and describes results for anomaly identification through a model and a field examples.
