标准范围

本文件定义了将信息元素从建筑信息建模（BIM）映射到地理信息系统（GIS）的概念框架和机制，以根据特定用户需求访问所需信息。将BIM信息映射到GIS的概念框架由以下三种映射机制定义:-？BIM到GIS透视定义（B2G PD）；-？BIM到GIS元素映射（B2G EM）；-？BIM到GIS LOD映射（B2G LM）。本文件不描述BIM和GIS模型之间的物理模式集成或映射，因为两个异构模型之间的物理模式集成或映射非常复杂，可能会导致各种模糊问题。在BIM和GIS之间开发一个统一的信息模型是一个理想的目标，但这超出了本文件的范围。本文件的范围包括以下内容:-？BIM到GIS概念图需求描述的定义；-？BIM到GIS概念图框架和组件的定义；-？定义从一个模式导出到另一个模式的映射。以下概念不在范围内:-？任何特定映射应用要求和机制的定义；-？BIM和GIS之间的双向映射方法；-？定义BIM和GIS之间的物理模式映射；-？定义BIM和GIS之间的坐标系映射。注:对于涉及地理参考相关要求的案例，以提供基于GIS的BIM模型的位置和方向，存在其他标准，如ISO 19111和Geo上buildingSMART的信息交付手册（IDM）-参考BIM。-？BIM和GIS之间关系映射的定义；-？应用程序模式的实现。

This document defines the conceptual framework and mechanisms for mapping information elements from Building Information Modelling (BIM) to Geographic Information Systems (GIS) to access the required information based on specific user requirements.The conceptual framework for mapping BIM information to GIS is defined with the following three mapping mechanisms:—    BIM to GIS Perspective Definition (B2G PD);—    BIM to GIS Element Mapping (B2G EM);—    BIM to GIS LOD Mapping (B2G LM).This document does not describe physical schema integration or mapping between BIM and GIS models because the physical schema integration or mapping between two heterogeneous models is very complex and can cause a variety of ambiguity problems. Developing a unified information model between BIM and GIS is a desirable goal, but it is out of the scope of this document.The scope of this document includes the following:—    definition for BIM to GIS conceptual mapping requirement description;—    definition of BIM to GIS conceptual mapping framework and component;—    definition of mapping for export from one schema into another.The following concepts are outside the scope:—    definition of any particular mapping application requirement and mechanism;—    bi-directional mapping method between BIM and GIS;—    definition of physical schema mapping between BIM and GIS;—    definition of coordinate system mapping between BIM and GIS.NOTE          For cases involving requirements related to Geo-referencing for providing the position and orientation of the BIM model based on GIS, there exist other standards such as ISO 19111 and the Information Delivery Manual (IDM) from buildingSMART on Geo-referencing BIM.—    definition of relationship mapping between BIM and GIS;—    implementation of the application schema.
