Requirements of the data to be used for resource appraisal

General principles in evaluation and selection of data to be included in computer processible files intended for use in assisting regional resources appraisal are discussed against the background of activities related to file assembly at the Geological Survey of Canada. Some of the principles discussed are currently being implemented in the assembly of files at the GSC where they apply to the specific data being collected. Others are apparent from our analysis and would be applied if different data were being collected. The files currently being assembled at the Survey are intended to assist the commodity geologists in all project-related activities, one of which is regional resource appraisal. Prior to the commencement of data assembly, each data item considered for inclusion in the data files was scrutinized by members of the Economic Geology Subdivision in order to establish how it would contribute to the overall objectives of the file. At the same time strict definitions of each item were established. The main criteria applied to each data item considered for inclusion in the files were (a) the necessity of the item to satisfy the objectives of the file within the practical limitations of the resources available and (b) the general availability of the item. The characteristics found necessary to ensure integrity of the data files were (a) uniformity—the same definitions must apply to each item of similar type, (b) consistency—analytical results should be of the same method or differences noted in order that the data may be compared, and (c) mutual exclusiveness—especially when dealing with data referring to size. Such data should never be repeated in another part of the file or be included as part of another item.This paper was presented at the International Geological Correlation Program (IGCP) Project 98 entitled Standards for Computer Applications in Resource Studies held at Loen, Norway, September 27–October 1, 1976.     

由野外实测数据直接生成MAPGIS地质基础图件方法

传统纸介质手工制图存在信息实时再现滞后、共享交换不便等弊端,即便目前普遍使用计算机制图,也只是对纸介质底图进行二次描绘,不是真正意义上的计算机数字化制图和专业应用.因此,由野外实测数据直接进机处理生成地质基础图件,已成为专业人员在实际工作中急需解决的实际问题.笔者尝试以中国地质大学开发的MAPGIS6.6为主,辅以常用图表处理软件等,将原始数据转换成MAPGIS明码格式文件,导入成图系统,经系统处理直接成图,基本解决了野外实测数据直接进机处理生成地质基础图件的问题,其成图精度高,基本图形、数据共享,成果信息实时再现,能够进行基本的空间分析,可实现信息全息化,成图质量可通过源数据检查等.
