This document establishes the core principles and specifications for enabling structured and semantically consistent information exchange between BIM and GIS. It provides a comprehensive framework for understanding, planning, and implementing information exchanges that span both the BIM domain and the GIS domain. This document provides a conceptual framework, built around eight perspectives on BIM-GIS information exchange: life cycle, process, product, data, exchange, actor, geospatial, and standards perspectives, how they shape, dictate, or constrain the structuring and execution of information exchanges, and the relationships between them and their application to specific use cases. It also addresses the following key elements: Requirements definition and hierarchy for BIM-GIS information exchanges Services enabling exchange and integration, transformation, query and analysis, and visualization and communication Functions supporting spatial registration and georeferencing, data harmonization, linking, analytical operations, and workflow management Resources including data and information types, formats, and their characteristics Repositories for centralized data management, translation and integration, and specialized storage It provides guidance on: Use case definition, services, and functions specification Application schema considerations addressing fundamental differences between BIM and GIS data structures Data resources management including objects, entities, and features Position and location management including georeferencing levels, metadata requirements, and implementation tasks Coordinate reference system selection and transformation parameters Georeferencing, including levels of georeferencing, metadata requirements and georeferencing tasks

 

This document provides guidelines for the data exchange between BIM and GIS through metadata. This document explains the role that metadata plays in facilitating data exchange within the framework of the standards referenced in ISO/DIS 23143-1, Clause 6.3 (Metadata resources). This document offers a perspective on leveraging metadata to ensure interoperability between BIM and GIS. It builds on the core principles established in ISO/DIS 23143-1 by presenting how metadata supports communication between the two domains, thereby facilitating seamless data exchange This document defines a framework for facilitating data exchange between Building Information Modelling (BIM) and Geographic Information Systems (GIS) through metadata-driven interoperability. It specifies methods for identifying and cross-mapping metadata elements in the GIS Metadata Schema (ISO 19115-1:2014 [2]), and for deriving BIM-side metadata from IDM Data Schema (ISO 29481-3:2022 [1]) to support semantic alignment and structured transformation between the two domains. ISO 29481-3:2022 [1] is used as a source to derive BIM-side metadata candidates for cross-mapping and is not treated as a metadata schema. The scope of this part includes: 1) Establishing metadata-based cross-mapping rules to support the semantic translation of information between BIM and GIS, including the use of BIM-side metadata candidates (derived from ISO 29481-3:2022 [1]) and GIS metadata elements (ISO 19115-1:2014 [2]); 2) Supporting bidirectional information requests and responses, where each domain (BIM or GIS) can serve as either information provider or consumer.
