【摘要】 空间数据集成方法研究是解决GIS数据共享的关键技术之一，它已成为当前信息化社会的研究热点。基于地质灾害的异源空间数据集成方法研究，是搭建地质灾害相关GIS平台和进行地质灾害分析的前提。基于地质灾害的异源空间数据集成汇集了测绘和地质等行业的空间数据，行业性的数据冲突给传统单一行业由数据采集带来的多源空间集成方法带来了新的挑战。本文介绍了传统空间数据集成的研究成果和基于地质灾害空间数据集成研究的现状；分析了异源空间数据的表达内容和特点；用测绘行业的数据处理的思想对测绘和地质行业空间数据的空间特征和属性特征的集成方法进行探讨；并且还研究了集成处理过程中数据的质量控制方法。最后，通过对三峡地质灾害相关平台搭建中异源空间数据集成方法讨论来对文中阐述的方法和理论加以印证。更多还原

【Abstract】 A research on the methods of spatial data integration, being one of the key technologies in the sharing of GIS data, has become the hot topic in current information society. It has become the precondition of constructing GIS frame about geologic hazard and deeply studying geologic hazard to research on the ways of integrating the spatial data from different trades about geologic hazard. Because there are different kinds of the spatial data from surveying and mapping and geologic in the integration, it has become a new challenge to the past ways of integration that the data from trades crash into each other.Firstly, the paper introduces the research fruits that have been gained and the status quo of studying the ways of integrating the spatial date from different trades about geologic hazard. Secondly, the paper says the content and characteristic of the spatial data from different trades. Thirdly the paper discuss the ways of integrating the feature and attribute about spatial data from surveying and mapping and geologic. And then the paper makes clear how to control the quality of integration. In the end, the paper explain those ways of integration is valuable by discussing the ways of integration in constructing GIS frame about Tree-gorge geologic hazard.更多还原
