矿产预测评价基础数据的入库策略探讨与实现

Realization of the Loading Strategy of the Basic Evaluated Data of Mineral Resources

矿产数据具有反复使用、长期利用的价值,是国家的宝贵财富,十分有必要把矿产数据入库进行统一管理并探讨数据入库中遇到的问题。在论述矿产预测评价基础数据建设重要性的基础上,结合数据的完整性、属性精度、逻辑一致性、空间精度、时间精度等检查内容,把数据检查分为基本数据检查和详细数据检查两大部分,划分出数据详细检查的层次,明确各层次的检查内容并提供解决办法;解决数据装载中数据预处理和文件格式转化的难题,最后借助ArcGIS和MapGIS实现技术开发。

The data of mineral resources can be repeatedly used for a long time and are precious wealth of the country,so it is necessary to perform a systematic management of the data. Based on a discussion of the importance of the resource-evaluated database,and combined with integrity of the data, attribute data accuracy, logic consistency, space accuracy and time accuracy,this paper divides data checking into the two parts, i.e., basic data checking,and explicit data checking and provides the solution to data checking. The authors also successfully solve the problem of the data pretreatment and the document format conversion and achieve the technique development with the help of the ArcGIS and MapGIS.
