Study on the 3D geological data model

The 3d data model is the definition and method of spatial data organization and the basic of geological modeling and exploiting, at the same time, it is a hot and difficult problem in many relational fields. By analyzing of 3 dimension data model, such as gird, triangle irregular networks model and boundary expression, then a data model, 3 dimension geological generalized map, is built based on the data of geological drilling. An example shows the effectiveness and feasibility of the modeling
