This document defines a structure that is suitable for binding content components and specific encoding formats. It also provides an implementation schema for binding a concrete, implementable, conformance-testable coverage structure as defined in ISO 19123-2.

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.

The binding between the content and a specific encoding format will be defined in the subsequent parts of ISO 19163.

ISO/TS 19163-1:2016 does not address LiDAR, SONAR data and ungeoreferenced gridded data.

The logical data structures and the rules for encoding the content components will be addressed in the subsequent parts of ISO 19163.

ISO/TS 19159-2:2016 also standardizes the service metadata for the data capture method, the relationships between the coordinate reference systems and their parameters and the calibration procedures of airborne lidar systems as well as the associated data types and code lists that have not been defined in other ISO geographic information international standards.

The framework defined in ISO/TS 19158:2012 enables a customer to satisfy itself that its suppliers, both internal and external, are capable of delivering geographic information to the required quality. Fundamental to the framework is the assurance of the supplier's ability to understand and meet the quality requirements. Through the quality assurance framework both the customer and the supplier are able to consider the quality required at the earliest opportunity in the production/update process.

Principles and responsibilities of the relationship between the customer and the supplier that facilitate the framework are provided. The responsibility for the quality assessment procedure is shared between the customer and the supplier.

ISO/TS 19158:2012 is applicable to customers and suppliers of all geographic information where the quality of the product may be impacted upon by the supplier's processes in any of the following scenarios:

1) there is an agreement or legislation for the supply of data acquisition services,

2) data acquisition services are being tendered for, and

3) one or more suppliers exist in the supply chain.

ISO/TS 19158:2012 is not applicable for the supply of legacy datasets or ?off the shelf' products where there is no further data production or update activity to manage.

The encoding rules described in this document are not applicable for encoding UML application schema for geographic features (see ISO 19136 for those rules).
