【摘要】：区域地质调查是一项公益性质的基础地质工作,几十年来在支持我国经济发展上发挥着十分重要的作用。近年来,信息化技术和数据库技术发展日趋成熟,这也推动了数字地质填图技术的发展,运用计算机等信息化技术进行区调工作优势明显,已经被广泛应用,应用数字化地质填图技术有助于不同行业对地质类信息的共享使用,也有助于对所掌握数据的更新、管理,对提高区调工作的质量和效率大有帮助。近年来,国内的数字地质填图工作已经逐步在地质工作中推广普及,但在系统设计和操作易用性方面仍存在一些不足,这对于区调工作的数字化发展产生了不利影响。本文结合黑龙江省战备村等1:5万区域地质调查项目,总结了实际工作中的经验与方法,同时结合数字地质填图技术的基本理论,总结出了项目工作过程中室内、室外资料处理和1:5万地质图数据库建库这几方面的常见问题和处理方法。具体的研究内容包括数字地质填图工作中的PRB过程,适合本项目工作区地质特征的PRB字典库设计及部分数据表结构设计,地质图空间数据库建库方法,数据精度控制,剖面自动生成等问题。在地质图数据库建设方面,使用数字填图系统的建库方法理论,完成了实际材料图中自动为要素类数据赋值、空间数据属性自动继承,输入空间属性数据等建库工作。按照1:5万区域地质图空间数据库建库国家标准,完成了1:5万战备村等两幅空间数据库的建库工作,探讨了适用于本工作区的工作方法和数据结构设计。数字地质填图技术优于传统区域填图方法,但不可避免存在一定的缺点,本文结合地质图数据库建设探讨了对数据质量的控制方法和生成实测剖面图等方面存在的问题,通过研究分析这方面的问题,可以为更多参与数字地质填图的工作人员用以借鉴,提高数字地质填图效率,为高质量完成填图工作提供保证。
[Abstract]:Regional geological survey is a commonweal basic geological work, which plays a very important role in supporting the economic development of our country in recent decades. In recent years, the development of information technology and database technology has become more and more mature. This has also promoted the development of digital geological mapping technology. The use of information technology such as computers for regional mapping has obvious advantages and has been widely used. The application of digital geological mapping technology is helpful to the sharing and use of geological information in different industries. It also contributes to the updating and management of available data, and to the improvement of the quality and efficiency of regional mapping. In recent years, digital geological mapping in the country has been gradually popularized in geological work, However, there are still some deficiencies in system design and operational ease of use, which have a negative impact on the digitization development of regional geological work. This paper summarizes the experience and methods in practical work, and combines with the basic theory of digital geological mapping technology, sums up the indoor work of the project, Common problems and processing methods in outdoor data processing and 1: 50 000 geological map database construction. The specific research contents include the PRB process in digital geological mapping. The design of PRB dictionary database and part of data table structure are suitable for the geological features of the work area of the project, the method of building geological map spatial database, data precision control, section automatic generation, etc. In the aspect of geological map database construction, Based on the theory of building database of digital mapping system, the automatic assignment of element class data and the inheritance of spatial data attributes in the actual material map are completed. According to the national standards for the establishment of the spatial database of the 1: 50,000 regional geological map, the construction of two spatial databases, such as 1: 50,000 war readiness villages, was completed. The working method and data structure design suitable for this work area are discussed. The digital geological mapping technique is superior to the traditional regional mapping method, but it inevitably has some shortcomings. Based on the construction of geological map database, this paper discusses the control methods of data quality and the problems existing in the generation of measured profiles, and analyzes the problems in this respect through research and analysis. It can be used for reference by more people involved in digital geological mapping, improve the efficiency of digital geological mapping, and guarantee the completion of mapping work with high quality.
