摘要
多样的勘察手段从多个方面对地质灾害体进行了揭露和记录,提供了丰富的数据资料,基于这些数据建立合理的地质模型是在三维GIS中表现地质灾害体的重要基础。本文以面向对象分析方法对地质灾害勘察中获取的数据及成果进行抽象分类,对不同的数据类型建立相应的地质模型进行表达,并结合实例进行了验证,取得了预期的效果。
Various survey methods provide detailed and comprehensive data which from different aspects describe and record the geologic hazard entity. Geologic model based on these data is very essential to display these entities in 3-D GIS, In this article object-oriented analysis is imported to classify the data from geologic hazard survey in the abstract, and the corre-spondent geologic models related to different survey methods are built. In the end the models are tested with a landslide display in 3D GIS which proves good.
