| Abstract: | Three-dimensional geological model is the focus in contemporary geology research.In model construction process,the data structure of foundational data exists in numerous data structures.With graphic and text data types and formats of three-dimensional geological model briefly discussed,the integration,amalgamation and precision match of different structural foundational data are analyzed.The generation,transmission and accumulation of model error are evaluated from the viewpoint of initial model data input and model system operation control.Some measures,methods of error reduction and model accuracy promotion are put forward. |
| Keywords: | 3D geological model data construction data analysis and pretreatment error analysis control |
