摘要
将数据融合的概念与理论引入到地学数据的处理中，在分析地学数据特点的基础上，给出了地学数据融合的一般模式；对空间数据融合处理的特点、优选方法、需注意的问题作了说明；
Data from geoscience study is a typical kind of spatial data.Usually,they have different sources,variant formats and metric units.How to use these data corporately in order to obtain more accurate and reliable results is one of the key problems in the geo information processing.This paper introduces the conception and theory of data fusion to the geo data processing.Based on the analysis of the characteristics of geo data,the authors provide a general scheme for the geo data fusion,as well as explaining the features,the preferred method and some problems which should be paid special attention in the procedure of geo data processing.
