一种地矿3维数据模型集成方法的研究

RESEARCH ON THE INTEGRATION METHOD OF MINE 3D DATA MODEL

摘要: 三维空间数据模型是三维GIS研究的核心问题。由于3维目标和应用的复杂性,一种数据模型很难满足不同的需要,因此数据模型集成成为三维空间数据模型发展的重要方向。本文结合地矿的空间特性,提出采用边界法和八叉树法集成的方法。

Abstract: D spatial deta model is the center of the research on 3D GIS.As the complex of 3D aim and application,a data model could not meet different needs,and the integration of data model becomes the important direction of the development of 3D data model.In the paper,according to the spatial feature of mine,an integration of data model based on BR and Octree is presented.
