This is a forward & inverse modeling of gravity & magnetic anomaly, which is developed under Windows operating system with friendly interface. As for gravity and magnetic anomaly due to area, it is able to make visual forward and inverse modeling for the whole plane by using mature 2.5D to carry out three-dimensional inverse modeling, which provides convenient means for prompt interpretation of plane anomaly. The selected model is a prism with horizontal finite length, of which the section is discretionary polygon and its discretionary combination is able to approximate to geological mass of complicated configuration. The interpreter can intuitively build model and dynamically modify model on computer screen according to the measured configuration of gravity & magnetic anomaly field, and at the same time, it is possible for him to see the fit between model gravity & magnetic field and measured anomaly. Furthermore, it is possible to promptly and intuitively inverse the physical properties and configuration of model. Because of strong functions and convenient operation of this program, the user can concentrate on the target problem to be settled, so as to improve the inverse efficiency of anomaly as well as the effect of interpretation.
