摘要
地质数据内容复杂,数据量大,抽样是检查地质数据质量不可缺少的方法。但到目前为止,地质数据的抽样检查基本上采用百分比抽样方案及简单随机和分层抽样方法。本文是在制定地质数据质量检查评价规范过程中进行有关研究的基础上写成的。首先阐述国内外用于数据,特别是空间数据抽样检查的标准及相关研究的现状,并结合地质数据的特点,分析适用于地质数据质量检查的抽样技术,探讨解决不同类型地质数据的抽样方案和抽样方法。
Sampling inspection is an indispensable method for quality inspection of geological data. However, percent sampling has been mainly used for sampling inspection of geological data till now. The paper first describes the states of standards and researches related to sampling inspection for data, especially spatial data. Then it analyzes which standard is suitable to be a base standard for quality inspection of geological data according to its characteristics. In the end, the issues about sampling schema for quality inspection of different types of geological data are discussed.
