AutoCAD-based automatic mapping method for adaptive curve trend

Abstract

The invention discloses an automatic mapping method based on an AutoCAD adaptive curve trend, which is applied to the technical field of geological exploration mapping, and comprises the following steps: S1, copying a lithologic pattern map library file, and importing a geological cross-section diagram into AutoCAD; s2, measuring a plotting scale; s3, establishing a ground line of the geological section, a geological boundary line and a selection set of stratum type description; s4, topological analysis is carried out on the selection set, and a topological region result corresponding to the stratum type is obtained; s5, connecting a stratum type database, and querying coordinates of the geological lithologic pattern information and the stratum type; s6, inquiring lithologic pattern information in the geological lithologic pattern library file; s7, filling of lithologic patterns of the geological cross-section diagram is completed through AutoCAD; according to the method, the complex geological cross-section diagram filling work can be adaptively processed, the workload is greatly reduced, the efficiency of the filling work is improved, filling is more standard and attractive, the filling format is unified, and the filling effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of geological exploration and mapping, in particular to an automatic mapping method based on AutoCAD adaptive curve trend. Background technique [0002] A geological section map is a map showing geological phenomena and their interrelationships on a geological section at a certain scale. The combination of geological section map and geological section map can obtain the three-dimensional concept of geological structure. Geological section map is one of the important geological section maps. It is a cross-sectional map obtained by tangent to the terrain with an imaginary vertical plane along a certain direction on the surface. The intersection line between the section and the ground is called the section line. A geological section map is a map that uses a certain scale to record and reveal the relationship between landforms and internal structures in a section in a certain direction. It can be compiled thr...
