Introduction
The integration of Building Information Modelling (BIM) and Geographic Information Systems (GIS)
represents a critical evolution in how the built environment is planned, delivered, and managed. As digital
transformation reshapes the architecture, engineering, construction, and operations (AECO) sector, the
need for seamless information exchange across scales and the knowledge domains that support them is
becoming essential.
BIM and GIS were developed independently to address different industry needs. BIM emerged to support
the detailed design, construction, and operation of individual built assets through multidimensional digital
representations and collaborative workflows. Initially focused on buildings, BIM has expanded to encompass
infrastructure including roads, bridges, railways, and other civil engineering works. GIS, conversely, was
developed to define phenomena in the real world as geographical features under a unified spatial reference
system, and then to abstract these geographical features into points, lines, areas, and volumes at different
scales. While GIS excels at processing, visualising and managing all types of geographical features within
different spatial scopes, BIM provides micro-scale precision for asset-specific information.
Both domains are converging and therefore call for more structured workflows and specific strategies
to overcome current incompatibilities in how they individually structure, store, process, and visualize
information. These differences extend across coordinate systems, semantic representations, geometric
paradigms, levels of granularity, and data access methods.
This international standard addresses these challenges by establishing core principles and specifications
for structured, semantically consistent information exchange between BIM and GIS. It recognizes that
interoperability between these domains is essential for the AECO sector to meet contemporary demands for
sustainable development, resilient infrastructure, and efficient asset management.
The standard adopts a perspective-based approach, recognizing that different stakeholders view BIM-GIS
information exchange through distinct lenses shaped by their roles, responsibilities, and objectives. Eight
fundamental perspectives are identified: life cycle, process, product, data, exchange, actor, geospatial, and
standards. Understanding which perspective drives a particular information exchange ensures it fulfils its
intended purpose.
This document establishes the foundational framework. It defines key concepts, describes technical
requirements, and identifies critical elements including requirements, services, functions, resources, and
repositories. Subsequent parts address metadata exchange (Part 2), geometric representation concepts,
semantic alignment, and process quality.
The approach presented herein builds upon existing international standards in both domains while
providing practical guidance for their coordinated application. By enabling seamless data flow between BIM
and GIS systems, this standard supports informed decision-making throughout the entire life cycle of built
assets within their geographic setting, facilitating multi-scale analysis from building component to regional
infrastructure network, collaborative workflows across traditionally separate disciplines, and compliance
with regulatory requirements spanning both building and geographic domains.
This document is intended for:
— Project owners and asset managers defining information requirements
— Design consultants and BIM managers implementing information exchanges
— GIS specialists and geospatial engineers establishing coordinate systems
— Software developers creating interoperability solutions
— Standards bodies and policy makers establishing BIM-GIS integration requirements
— Educators and researchers advancing BIM-GIS integration practices

Core principles and specifications
1 Scope
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

5 Perspectives on BIM-GIS information exchange
5.1 General
Different perspectives can be adopted when structuring and enabling information exchanges between BIM
and GIS. These perspectives are adopted by the different practitioners involved in an exchange and will
vary depending on their role, responsibilities, expectations and requirements, among others. This section
presents eight different perspectives on BIM-GIS information exchange ( asset life cycle or product life
cycle , process , product , data, exchange, actor,, geospatial and standardization), and discusses how these
perspectives will shape, dictate or constrain the structuring and execution of these information exchanges.
These eight perspectives are part of a whole as illustrated in Figure 1.
Figure 1 — Perspectives on BIM-GIS information exchange

ISO/DIS 23143-1:2026(en)
Each perspective will stem from a need for specific data or information in support of a process or a key
decision point. Certain perspectives may be adopted more readily by specific stakeholder groups (e.g. Clients
adopting a life cycle perspective or manufacturers adopting a product perspective), whereas others will be
universal (e.g process, data and exchange perspectives). Clearly understanding from what perspective the
BIM-GIS information exchange is being initiated is important to ensure that it fulfils its intended purpose.
Indeed, each domain brings distinct practices, workflows, and standards. For each perspective, domain-
specific considerations are provided to ensure that information exchanges adequately address requirements
and capabilities from both sides. Users should consider both BIM and GIS domain aspects when planning
and implementing exchanges, recognizing that different stakeholders may prioritize different perspectives
based on their domain expertise and role.
Moreover, information exchanges between BIM and GIS are not unidirectional. Each perspective may involve
information flowing from BIM to GIS, from GIS to BIM, or bidirectionally, depending on the specific use case,
life cycle phase, and actor requirements. The exchange characteristics specified for each perspective indicate
typical patterns, but implementers should adapt these to their specific context. This approach extends the
BIM to GIS Perspective Definition (B2G PD), defined in ISO/TS 19166:2025, which supports perspectives on
information representation depending on specific use cases and includes methods for specifying what data
are needed, how to extract and integrate data, and how to represent the integrated information.
