摘要: 三维数据结构是三维GIS研究的重点。三维栅格数据结构在数字影象、数字高程模型等领域得到了广泛应用。从栅格的编码、栅格的空间分析等方面对三维栅格数据结构进行研究,并以一个具体的矿床为例,对应用三维栅格数据结构进行矿体块段建模、特定范围内储量计算等空间分析时涉及的技术和方法进行了论述。提出了今后在研究和应用三维数据结构时的建议和展望。

关键词: GIS, 三维栅格数据模型, 空间分析, 块段建模, 储量计算

Abstract: 3D data structure is the focus in 3D GIS research. 3D grid data structure has gained wide application in fields such as digital image, digital elevation model, etc. The paper studies the 3D grid data structure from the aspects of grid coding, its spatial analysis, etc. It is exemplified by the study of a real deposit, which involves the techniques and method used for the spatial analysis by 3D grid data structure in the ore block modeling, reserve estimation in specified area, etc. Suggestions and prospect are also made for the future study and application of 3D data structure.

Key words:  GIS, 3D gird data model, spatial analysis, Block modeling, Ore reserves estimation
