Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 %
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 19158 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.

Introduction
This Technical Specification provides a quality assurance framework for the producer and customer in
their production relationship. It identifies methods of managing the quality of production more efficiently
and effectively. It enables innovation and continual improvement within the context of existing:
— geographic information quality principles and quality evaluation procedures, and
— quality management systems.
With ever increasing demands in value and quality in the Geographic Information (GI) market the
framework facilitates the production of a product that meets requirements in terms of cost, quantity,
quality and timeliness.
Through the application of the framework there are opportunities for:
— better understanding of requirements by all involved in production and update especially within
multiple producer environments,
— reduced data throughput time,
— reduced rework,
— improved data quality, and
— increased confidence within a mutually beneficial relationship leading to lower costs for both
supplier and organization.
ISO 19157 establishes the principles for the description of geographic data quality and specifies
components for reporting quality information as well as procedures for the evaluation of geographic
data quality.
The quality assessment procedure, as defined in this Technical Specification, is a second-party (customer)
conformity assessment activity.
TECHNICAL SPECIFICATION ISO/TS 19158:2012(E)
Geographic information — Quality assurance of data supply
1 Scope
This Technical Specification provides a framework for quality assurance specific to geographic
information. It is based upon the quality principles and quality evaluation procedures of geographic
information identified in ISO 19157 and the general quality management principles defined in
[2]
ISO 9000 .
The framework defined in this Technical Specification 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.
This Technical Specification 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:
— there is an agreement or legislation for the supply of data acquisition services,
— data acquisition services are being tendered for, and
— one or more suppliers exist in the supply chain.
This Technical Specification 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.
2 Conformance
Any organization claiming conformance with this specification shall pass all of the requirements
described in the abstract test suite presented in Annex A.

4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
1) To be published.
4.1
customer
organization or person that receives a product (4.3)
[SOURCE: ISO 9000:2005, definition 3.3.5]
NOTE The customer can be internal or external to the supplier (4.11) organization.
4.2
process
set of interrelated or interacting activities which transforms inputs into outputs
[SOURCE: ISO 9000:2005, definition 3.4.1]
NOTE The process may be broken down further into elemental activities [sub-process (4.10)] as is deemed
necessary to control the quality (4.4) of the process.
4.3
product
result of a process (4.2)
[SOURCE: ISO 9000:2005, definition 3.4.2]
4.4
quality
degree to which a set of inherent characteristics fulfils requirements
[SOURCE: ISO 9000:2005, definition 3.1.1]
NOTE For the purposes of this Technical Specification the quality characteristics of a product (4.3) include:
— data quality (the elements of which are described by ISO 19157),
— volume of delivery,
— schedule of delivery, and
— cost of production and/or update.
4.5
quality assessment procedure
procedure by which a customer (4.1) assures that its suppliers (4.11) are capable of consistently

NOTE The assessment procedure is a second-party (customer) conformity assessment activity.
4.6
quality assessment result
output of the quality assessment procedure (4.5)
4.7
quality assurance
part of quality (4.4) management focused on providing confidence that quality requirements will be fulfilled
