建筑信息模型（BIM）和地理信息系统（GIS）往往被集成，以实现更精细化的城市管理。行业基础类（IFC）和城市地理标记语言（CityGML）是BIM和GIS中广泛使用的标准。这两个标准转换的主要问题在于它们在几何和语义上的差距。本文介绍了一种基于本体的规则映射方法，通过坐标系转换、几何表达式转换和语义映射实现IFC到CityGML的转换。在语义映射方面，我们设计并建立了规则，实现了IFC模型到CityGML细节层次0（LOD0）到LOD4模型的有效映射，该映射基于实体、外观属性和建筑属性。为了充分展示整个过程，我们对几种IFC模型的转换进行了详细阐述。
Building information modeling (BIM) and geographic information system (GIS) are often integrated to achieve more refined urban management. Industry Foundation Classes (IFC) and City Geography Markup Language (CityGML) are widely used standards in BIM and GIS. The main problem of the transformation of these two standards lies in the gap between them in geometry and semantics. This article introduces an ontology‐based rule mapping approach, achieving the transformation from IFC to CityGML through coordinate system conversion, geometric expression conversion, and semantic mapping. For semantic mapping, we have designed and established rules, enabling the effective mapping of the IFC model to the CityGML level of detail 0 (LOD0) to LOD4 model based on entities, appearance properties and building properties. To fully demonstrate the entire process, we give a detailed elaboration of the conversion of several IFC models.
