MapGIS 3D GeoModeler is a tool for three-dimensional geological modeling, visualization, and analysis. It integrates multiple sources of geological data such as boreholes, profiles, and physical and chemical exploration, and uses automatic and semi-automatic rapid modeling techniques to construct structural and attribute models containing complex geological features such as faults and lenses. It achieves the integrated construction of geological models throughout the entire process and provides visualization expression and analysis functions based on geological features.
