地球化学数据处理与分析软件设计与实践

Design and practice of geochemical data processing and analysis software

为加强我国与世界各国的国际地学合作,推广我国具有自主知识产权的软件技术方法,支撑世界一流新型地质调查局建设,本文利用现代计算机技术、地理信息技术、空间数据库技术和多元统计分析方法等,以组件对象模型(COM)组件技术为基础,利用美国环境系统研究所(ESRI公司)的ArcGIS Engine应用程序编程接口(API)作为地理空间分析处理的研发框架,使用C和C++作为软件各项功能的开发语言,研发了地质勘查数据处理与分析系统(GeoExpl)国际版软件系统,搭建了地球化学数据处理、数据分析、数据管理和地球化学多类型专题图制作一体化的勘查地球化学业务处理流程体系,创造性地以工作空间为管理单元实现了分析数据、处理数据、图形数据和制图成果等综合数据的数据集成管理。通过GeoExpl国际版软件的研发,实现了地球化学数据处理到成果共享的全流程一体化,打破了以往单一国外软件在技术上的垄断,实现了地球化学数据处理与分析各类方法的整合与创新算法研发,本软件在多个项目和国家应用得到积极反馈,证明了该软件技术符合国际合作的需求。

In order to strengthen international geoscientific cooperation between China and other countries,promote China’s software technologies and methods with independent intellectual property rights,and support the construction of a new type of world-class geological survey bureau,this paper used modern computer technology,geographic information technology,spatial database technology,and multivariate statistical analysis method and developed an international software for geological survey data processing and analysis system(GeoExpl)by using component object model(COM)technology and the ArcGIS Engine application programming interface(API)of the Environmental Systems Research Institute(ESRI)as the development framework for geospatial analysis and processing.In addition,C and C++were employed as the development languages for each function of the software,and a process system of survey and geochemical business processing was set up,which integrated geochemical data processing,data analysis,data management,and production of geochemical multi-type thematic maps.The data integration management of analysis data,processing data,graphic data,and cartographic results was realized by taking the workspace as the management unit creatively.Through the research and development of GeoExpl,the integration of the whole process from geochemical data processing to result sharing was realized,breaking the previous monopoly of foreign software in terms of technology and realizing the integration of various types of methods and innovative algorithm research and development for geochemical data processing and analysis.The software has received positive feedback from its application in a number of projects and countries,proving that the technology of the software meets the needs of international cooperation.
