Designing And Actualizing Of The System Of Measured Geological Section Production In The Software Of The Regional Geological Practical Mapping

The regional geological mapping is an important part of geological work and foundation study. It has covered the Sedimentation, the Intrusion, the Metamorphism, the Tectonics, the Palaeontology, the ancient historical geology and so on in the geological process. As a significant content in geological reconnaissance of the field geological mapping work, the establishment of measured main stratagraphic section is the more important step in the ascertaining and dividing the plotting unit, unifying acquaintance, and instructing the surface mapping, it needs the massive spatial data calculation, and the troublesome plotting tasks in the establishment process, especially in the field geological mapping teaching, spatial relationship analysis of the stratum and the lead position also is a difficult job. How to achieve the measured main stratagraphic section plane through computer in the field geological mapping process based on the modern science computation foundation both has the extremely vital significance to the production and the teaching.The designing and development of the measured geological section production system depending upon Visual Basic face programming tool foundation, constructs the field data analysis module, the data conversion module, the GPS data conversion module. Through analysis computation of the relationships of the lead and the stratum, builds the production of measured geological section drawing and the lead graphs, saves and prints images through the CaptureWindow function as well as the CreateBitmapPicture function. The system uses the designing pattern of lamination management in the development process, built the layers of the user operation, the system analysis and the Database. each of them organic synthesis, easy system maintenance and data management. The system based on the realization of the measured geological section, analyzes the fake obliquities of the bedded rocks body, and has reserved the attribute spot, the attribute borderline, the free graph insertion function, and has reserved the space for special rock layer (for example fault, intrusive mass and so on non-bedded rocks body) in the production of the section plane process.Further researches and developments of the system, using with the digital geological mapping, hopes to form a complete system of drawing of measured geological section and the cutting section of geological map, serves for the geological production and the field geological teaching.
