摘要
在分析地学数据的多尺度性基础上,提出顾及语义对地学数据进行多尺度划分,进而给出了顾及语义差异的多尺度模型序列;将无缝集成建模原理与多尺度建模机理进行耦合,提出了一种基于6层LOD的地上下无缝集成多尺度建模的体系结构,并在Geos3D V1.0平台中软件实现.应用试验表明,提出的顾及语义的地上下无缝集成多尺度建模方法,能够较为充分地利用有关地学数据对地上、地表和地下对象进行集成建模,为地学领域多尺度集成建模提供了一种新的方法和技术方案.
The multi-scale modeling of the aground-underground integrated space is the key technology for digital mine,digital city and digital geotechnical engineering.Analyzing the multi-scale geoscientific data,they were partitioned taking account of semantics so as to develop a series of multi-scale models,inclusive of semantic differences.Integrating the seamless modeling with multi-scale modeling,an architecture based on the 6-level LOD（level of detail） of the aground-underground integrated multi-scale monolithic modeling was proposed,which was implemented on the software platform Geos3D V1.0.Experimental application results showed that the method of aground-underground seamlessly integrated multi-scale modeling with semantics taken into account can take full advantage of geoscientific data to model the aground,surface and underground objects integrally,thus providing a new technological approach to the seamlessly integrated multi-scale modeling for geoscience.
