抽象的。近年来，三维虚拟室内/室外城市建模成为许多土木和工程应用，如疏散规划，应急和设施管理的关键空间信息框架。为了完成这些复杂的决策任务，需要建立多尺度、多源的三维城市模型。目前，建筑信息模型（BIM）和地理信息系统（GIS）被广泛用作建模源。然而，两个建模域之间的数据共享和信息交换仍然是一个巨大的挑战;而语法或语义方法并不能完全提供BIM到GIS的丰富语义和几何信息的交换，反之亦然。本文提出了一种新的方法集成BIM和GIS使用语义Web技术和资源描述框架（RDF）图。所提出的解决方案的新奇来自于将BIM和GIS技术集成到一个统一模型中的好处，即所谓的集成地理空间信息模型（IGIM）。该方法包括三个主要模块：BIM-RDF图和GIS-RDF图的构建，两个RDF图的集成，以及使用SPARQL通过IGIM-RDF图进行信息查询。IGIM从BIM和GIS RDF图生成查询，从而产生语义集成模型，该模型具有表示BIM类和GIS特征对象的实体。BIM-RDF和GIS-RDF之间的联系是通过SPARQL端点实现的，并通过使用具有互补属性、关系和几何形状的数据集和实体类的查询来定义。为了验证所提出的方法和它的性能，一个案例研究进行了测试，使用IGIM系统设计。
Abstract. In recent years, 3D virtual indoor/outdoor urban modelling becomes a key spatial information framework for many civil and engineering applications such as evacuation planning, emergency and facility management. For accomplishing such sophisticate decision tasks, there is a large demands for building multi-scale and multi-sourced 3D urban models. Currently, Building Information Model (BIM) and Geographical Information Systems (GIS) are broadly used as the modelling sources. However, data sharing and exchanging information between two modelling domains is still a huge challenge; while the syntactic or semantic approaches do not fully provide exchanging of rich semantic and geometric information of BIM into GIS or vice-versa. This paper proposes a novel approach for integrating BIM and GIS using semantic web technologies and Resources Description Framework (RDF) graphs. The novelty of the proposed solution comes from the benefits of integrating BIM and GIS technologies into one unified model, so-called Integrated Geospatial Information Model (IGIM). The proposed approach consists of three main modules: BIM-RDF and GIS-RDF graphs construction, integrating of two RDF graphs, and query of information through IGIM-RDF graph using SPARQL. The IGIM generates queries from both the BIM and GIS RDF graphs resulting a semantically integrated model with entities representing both BIM classes and GIS feature objects with respect to the target-client application. The linkage between BIM-RDF and GIS-RDF is achieved through SPARQL endpoints and defined by a query using set of datasets and entity classes with complementary properties, relationships and geometries. To validate the proposed approach and its performance, a case study was also tested using IGIM system design.
