Public information guidance systems — Part 1: Design principles and element requirements for location plans, maps and diagrams

ISO 28564-1:2010 specifies requirements and principles for the design and application of location plans, maps and diagrams used in public areas and workplaces to assist users to understand the environment, locate facilities and determine appropriate routes to reach those facilities. These location plans, maps and diagrams are referred to as location plans in ISO 28564-1:2010. Location plans are intended for use in, for example, shopping centres, stores, hospitals, bus and train stations, airports, sporting and entertainment complexes, urban areas, parks, gardens and countryside, public attractions, museums and office complexes. ISO 28564-1:2010 is not applicable to the design of escape plans, nor does it cover the design of directional and location wayfinding signs.

Systèmes de guidage destinés à l'information du public — Partie 1: Principes de conception et exigences pour éléments de plans, cartes et diagrammes de situation

L'ISO 28564-1:2010 spécifie les exigences et principes de conception et d'application des plans, cartes et diagrammes de situation utilisés dans les lieux publics et sur les lieux de travail pour aider les utilisateurs à comprendre l'environnement, localiser des installations et déterminer des itinéraires appropriés pour parvenir à ces installations. Ces plans, cartes et diagrammes de situation sont désignés par le terme général de «plans de situation» dans l'ISO 28564-1:2010. Les plans de situation sont destinés à être utilisés, par exemple, dans les centres commerciaux, les magasins, les hôpitaux, les stations de bus et les gares, les aéroports, les centres sportifs et les complexes récréatifs, les zones urbaines, les parcs et jardins; ainsi qu'à la campagne, dans les parcs d'attraction, les musées et les grands ensembles de bureaux. L'ISO 28564-1:2010 n'est pas applicable à la conception de plans d'évacuation et de secours et ne couvre pas la conception des panneaux de signalisation de direction et de localisation.

Overview

ISO 28564-1:2010 establishes essential requirements and design principles for creating effective public information guidance systems, specifically focusing on location plans, maps, and diagrams. This international standard supports the clear communication of spatial information in public spaces and workplaces, helping users understand their environment, locate facilities, and choose suitable routes.

The standard applies to a wide range of settings, such as shopping centres, hospitals, airports, transportation hubs, sports complexes, parks, museums, and office buildings. ISO 28564-1 is not intended for escape plans or the design of directional and wayfinding signage, focusing solely on the elements and best practices for location plans and informational maps.

Key Topics

• Design Principles: The standard details core principles for creating location plans, emphasizing user orientation, clarity, and accessibility. Plans should use standardized graphical symbols wherever possible and minimize unnecessary text or jargon.
• Element Requirements: Key components include a clear title, main map body, legend, and, when applicable, an index and scale. Essential designators like “You are here” and north indicators should be prominently included.
• Preparation and Data Gathering: The standard outlines a structured approach to gather relevant data-considering input from stakeholders, potential users, and physical site inspections-to inform the design scope and content.
• Consistency and Accessibility: ISO 28564-1 highlights the importance of design consistency for families of plans, as well as accessible design for all users (including those with disabilities). Considerations for color contrast and legibility, use of sans-serif fonts, and clear depiction of accessible routes are included.
• Positioning and Orientation: Effective placement of location plans is crucial. Plans should be installed at points where users require guidance, be easily visible, accessible, and oriented to match user approach.
• Testing and Maintenance: Prototyping and testing with representative users help ensure that plans are comprehensible and effective. Regular inspection, updating, and the use of durable, sustainable materials are also emphasized.

Applications

Compliance with ISO 28564-1 enhances wayfinding in diverse public and corporate environments by improving the quality and usability of location plans and maps. Organizations implement the standard to:

• Improve visitor experience: By providing intuitive, easy-to-understand maps, organizations help users navigate complex facilities efficiently and with confidence.
• Boost safety and efficiency: Correctly designed and positioned location plans aid in crowd management and reduce confusion, which is particularly valuable in high-traffic areas like transport terminals and entertainment venues.
• Demonstrate commitment to accessibility: Incorporating inclusive design principles ensures information is accessible to all, including people with disabilities.
• Support branding and information consistency: Applying consistent graphic standards across all location maps strengthens the visual identity and reliability of the guidance system.

Related Standards

To ensure a fully integrated public information guidance system, ISO 28564-1 should be considered alongside other relevant international standards:

• ISO 28564-2: Covers design principles for directional and location wayfinding signs.
• ISO 28564-3: Provides guidance on information index signs.
• ISO 28564-4: Outlines installation and assessment protocols for wayfinding systems.
• ISO 23601: Details requirements for escape and evacuation plans.
• ISO 7001, ISO 7010: Standards for public information and safety symbols.
• ISO 9186 series: Methods for testing the comprehensibility and perceptual quality of symbols.

By adopting ISO 28564-1 and its related parts, organizations can deliver clear, consistent, and user-friendly spatial information guidance, supporting safer, more inclusive, and more navigable public environments.

Introduction
Continued growth in travel and mobility within and between countries has generated a growing range
of wayfinding guidance systems and styles containing a wide variety of information. Such systems serve
various purposes, such as enabling users to:
— understand the range of facilities and points of interest present;
— understand the physical relationship between those facilities and points of interest;
— determine the best way to reach a required facility or point of interest given their mobility circumstances.
This document is concerned with location plans, maps and diagrams used to support wayfinding.
The purpose of this document is to provide principles on the design and use of location plans, maps and
diagrams to enable users to assimilate required information swiftly and accurately. It is not the intention
to limit design freedom unnecessarily, but to set guidelines and, where appropriate, specifications which
reflect relevant research and best practice.
Where appropriate, as part of an integrated wayfinding system, location plans, maps and diagrams are
used in association with fixed location signs and direction signs (see ISO 28564-2), information index signs
(see ISO 28564-3), hand-held maps, and IT applications, as well as human assistance. For guidelines on the
installation of wayfinding systems, please refer to ISO 28564-4 and the following part(s) of ISO 28564.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 17724 and the following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
location plan
plan, map or diagram displayed in public areas and workplaces to assist users to understand the environment,
locate facilities and determine appropriate routes to reach those facilities
Note 1 to entry: A location plan may include the physical display structure.
Note 2 to entry: The term diagram is included because, in some situations, a location plan can be schematic or exclude
or distort physical arrangements.
3.2
series of plans
group of the same or similar location plans which may be provided at different locations within a given area
3.3
main body
area within a location plan where the information related to the purpose of the location plan is given
4 General
4.1 Purpose
The purpose of a location plan is to provide orientation within a building or defined geographical area and
to enable users to reach destinations quickly and easily.
4.2 Conformity with existing standards
Symbols used on location plans shall be taken, where they exist, from ISO 7001 and ISO 7010.
If a new graphical symbol is required, the relevant International Standard (ISO 22727 or ISO 3864-3) shall
be used as part of the development process. The new graphical symbol shall be tested with the relevant
testing methods: comprehension testing shall be in accordance with ISO 9186-1, perceptual quality testing
shall be in accordance with ISO 9186-2, and symbol referent association testing shall be in accordance with
ISO 9186-3.
The public information symbols given in ISO 7001 may be reproduced in any colour. However, the
combination of safety colours and shapes specified in ISO 3864-1 shall be avoided to ensure that there is no
confusion between public information symbols and safety signs. This also applies to arrows where the use
of green and white shall be avoided to ensure that there is no risk of confusion with the direction arrows or
safe conditions, used for evacuation routes.
In addition, any colours used shall not conflict with the use of those colours within the location plan to
indicate a safety function.
ISO/DIS 28564-1:2025(en)
5 Preparation
5.1 Brief
Before design work is undertaken, the requirements and objectives of a location plan should be clearly
understood and expressed in a brief. The brief should include the area to be covered, the information to be
shown, as determined by the nature of the tasks that the expected users will wish to accomplish, and any
special requirements concerning information presentation.
If relevant, the brief should also define the requirements for location signs and direction signs (see
ISO 28564-2), guidelines for information index signs (see ISO 28564-3), guidelines for installation (see
ISO 28564-4), and guidelines or methods for coordination with location plans.
5.2 Gathering data
Sources of information will depend on whether the area to be shown is at the planning stage or already in
use. Where the area is at the planning stage, information may be obtained from the facility client and from
architects, interior/landscape designers, engineers and other professionals with knowledge relevant to the
current task. Where the facility is already in use, additional information can be obtained by consulting with
a) potential users of a location plan,
b) local police, shopkeepers, reception/information desk staff and others who might have experience of
wayfinding issues within the area to be covered, and
c) any existing location plans.
NOTE A site visit can be useful in gaining information regarding the site and its requirements, and, where
possible, to observe and document relevant behavioural patterns.
At the conclusion, the data gathered should be reconciled with the brief.
5.3 Area to be covered
The area to be covered by a location plan will often have logical boundaries, for example as defined by a
floor of a building or by a discrete local geographical area; however, in some circumstances this area may be
large or complex. The area covered by an individual location plan should not be such that it becomes difficult
for users to remember sufficient detail to reliably reach any location shown. In such circumstances, the area
should be divided into smaller units, each with its own location plan. Design consistency should be such that
users can easily recognize the family relationship.
5.4 Information to be shown
Examples of location-plan layouts are shown in Annex A.
Some considerations to determine the information to be shown are as follows.
a) The location of the users and the types and positions of the facilities about which they will require
information. See Figure A.1.
b) The proportion of the expected users for whom the use of the official local language(s) might be
insufficient.
c) Whether the location plan will need to show only specific information, for example, the locations of
different transportation stops. See Figure A.2.

ISO/DIS 28564-1:2025(en)
6 Design
6.1 Principles
The following should be taken into account in the design of a location plan.
a) The relevant information from sources described in Clause 5.
b) It shall consist at least of a title (see 6.2), main body (see 6.3) and, normally, a legend (see 6.4). It may
also include an index (see 6.5), a scale (see 6.6) and a north designator.
c) The use of text on the main body should be kept to a minimum.
d) The use of the official local language(s) might be sufficient. It is recommended that, if an additional
language is required, English should be used first.
e) When using text, jargon should be avoided and specialized terms should only be used where the target
audience is known to be familiar with them. Abbreviations should only be used where they are in
common use and well understood.
f) Text should always use font(s) with high legibility. A single sans-serif font family is recommended.
g) The text should be designed so that all the information it contains is clear and legible for users in a
standing or seated position to facilitate readability by those in wheelchairs.
h) Details should stand out clearly, including any appropriate designator showing the users' position.
i) In a series of plans, information should be illustrated and presented consistently, such as by using the
same symbols, terms and graphic style.
j) The method of representing the relationship between the site shown on a locat

3.1
location plan
plan, map or diagram displayed in public areas and workplaces to assist users to understand the environment,
locate facilities and determine appropriate routes to reach those facilities
Note 1 to entry: A location plan may include the physical display structure.
Note 2 to entry: The term diagram is included because, in some situations, a location plan can be schematic or exclude
or distort physical arrangements.
3.2
series of plans
group of the same or similar location plans (3.1) which may be provided at different locations within a given
area
3.3
main body
area within a location plan where the information related to the purpose of the location plan (3.1) is given
4 General
4.1 Purpose
The purpose of a location plan is to provide orientation within a building or defined geographical area and
to enable users to reach destinations quickly and easily.
4.2 Conformity with existing standards
Symbols used on location plans shall be taken, where they exist, from ISO 7001 and ISO 7010.
If a new graphical symbol is required, the relevant International Standard (ISO 22727 or ISO 3864-3) shall
be used as part of the development process. The new graphical symbol shall be tested with the relevant
testing methods: comprehension testing shall be in accordance with ISO 9186-1, perceptual quality testing
shall be in accordance with ISO 9186-2, and symbol referent association testing shall be in accordance with
ISO 9186-3.
The public information symbols given in ISO 7001 may be reproduced in any colour. However, the
combination of safety colours and shapes specified in ISO 3864-1 shall be avoided to ensure that there is no
confusion between public information symbols and safety signs. This also applies to arrows where the use
of green and white shall be avoided to ensure that there is no risk of confusion with the direction arrows or
safe conditions, used for evacuation routes.
In addition, any colours used shall not conflict with the use of those colours within the location plan to
indicate a safety function.

5 Preparation
5.1 Brief
Before design work is undertaken, the requirements and objectives of a location plan should be clearly
understood and expressed in a brief. The brief should include the area to be covered, the information to be
shown, as determined by the nature of the tasks that the expected users will wish to accomplish, and any
special requirements concerning information presentation.
If relevant, the brief should also define the requirements for location signs and direction signs (see
ISO 28564-2), guidelines for information index signs (see ISO 28564-3), guidelines for installation and
assessment(see ISO 28564-4), and guidelines or methods for coordination with location plans.
5.2 Gathering data
Sources of information will depend on whether the area to be shown is at the planning stage or already in
use. Where the area is at the planning stage, information may be obtained from the facility client and from
architects, interior/landscape designers, engineers and other professionals with knowledge relevant to the
current task. Where the facility is already in use, additional information can be obtained by consulting with:
a) potential users of a location plan;
b) local police, shopkeepers, reception/information desk staff and others who can have experience of
wayfinding issues within the area to be covered; and
c) any existing location plans.
NOTE A site visit can be useful in gaining information regarding the site and its requirements, and, where
possible, to observe and document relevant behavioural patterns.
At the conclusion, the data gathered should be reconciled with the brief.
5.3 Area to be covered
The area to be covered by a location plan will often have logical boundaries, for example as defined by a
floor of a building or by a discrete local geographical area; however, in some circumstances this area may be
large or complex. The area covered by an individual location plan should not be such that it becomes difficult
for users to remember sufficient detail to reliably reach any location shown. In such circumstances, the area
should be divided into smaller units, each with its own location plan. Design consistency should be such that
users can easily recognize the family relationship.
5.4 Information to be shown
Examples of location-plan layouts are shown in Annex A.
Some considerations to determine the information to be shown are as follows.
a) The location of the users and the types and positions of the facilities about which they will require
information. See Figure A.1.
b) The proportion of the expected users for whom the use of the official local language(s) can be insufficient.
c) Whether the location plan will need to show only specific information, for example, the locations of
different transportation stops. See Figure A.2.
PROOF/ÉPREUVE
6 Design
6.1 Principles
The following should be taken into account in the design of a location plan.
a) The relevant information from sources described in Clause 5.
b) It shall consist at least of a title (see 6.2), main body (see 6.3) and, normally, a legend (see 6.4). It may
also include an index (see 6.5), a scale (see 6.6) and a north designator.
c) The use of text on the main body should be kept to a minimum.
d) The use of the official local language(s) can be sufficient. It is recommended that, if an additional
language is required, English should be used first.
e) When using text, jargon should be avoided and specialized terms should only be used where the target
audience is known to be familiar with them. Abbreviations should only be used where they are in
common use and well understood.
f) Text should always use font(s) with high legibility. A single sans-serif font family is recommended.
g) The text should be designed so that all the information it contains is clear and legible for users in a
standing or seated position to facilitate readability by those in wheelchairs.
h) Details should stand out clearly, including any appropriate designator showing the users' position.
i) In a series of plans, information should be illustrated and presented consistently, such as by using the
same symbols, terms and graphic style.
j) The method of representing the relationship between the site shown on a location plan and the area
beyond should be considered. For example, an overview plan may be needed and/or it may be important
to show where entrances come from and where exits lead to.
k) The colour combination shown on a location plan should be considered to ensure legibility for all kinds
of users, for example, users with colour-vision deficiency.
l) Additional methods should be considered to make it useful for all kinds of users, for example, users with
vision impairment.
m) A three-dimensional view can be easier for users to understand than a two-dimensional view. However,
caution should be taken to minimize complexity and to ensure that other important details are not
obscured. It may be appropriate to show only selected landmarks in three dimensions. See Figure A.3.
n) Incorporating relevant architectural/environmental features may assist orientation and comprehension.
o) Wherever possible, the shape of the area covered should be reflected in a location plan.
p) High contrast and other graphic techniques, such as appropriate spacing and scaling, should be used to
ensure legibility under all normal viewing conditions.
q) Where fine detail is required, it can be appropriate to incorporate an enlarged v

Introduction
Continued growth in travel and mobility within and between countries has generated a growing range of
wayfinding guidance systems and styles containing a wide variety of information. Such systems serve various
purposes, such as enabling users to:
— — understand the range of facilities and points of interest present;
— — understand the physical relationship between those facilities and points of interest;
— — determine the best way to reach a required facility or point of interest given their mobility
circumstances.
This document is concerned with location plans, maps and diagrams used to support wayfinding.
The purpose of this document is to provide principles on the design and use of location plans, maps and
diagrams to enable users to assimilate required information swiftly and accurately. It is not the intention to
limit design freedom unnecessarily, but to set guidelines and, where appropriate, specifications which reflect
relevant research and best practice.
Where appropriate, as part of an integrated wayfinding system, location plans, maps and diagrams are used
in association with fixed location signs and direction signs (see ISO 28564-2), information index signs (see ISO
28564-3), hand-held maps, and IT applications, as well as human assistance. For guidelines on the installation
and assessment of wayfinding systems, please refer to ISO 28564-4.

5 Preparation
5.1 Brief
Before design work is undertaken, the requirements and objectives of a location plan should be clearly
understood and expressed in a brief. The brief should include the area to be covered, the information to be
shown, as determined by the nature of the tasks that the expected users will wish to accomplish, and any
special requirements concerning information presentation.
If relevant, the brief should also define the requirements for location signs and direction signs (see ISO 28564-
2), guidelines for information index signs (see ISO 28564-3), guidelines for installation and assessment(see
ISO 28564-4), and guidelines or methods for coordination with location plans.
5.2 Gathering data
Sources of information will depend on whether the area to be shown is at the planning stage or already in use.
Where the area is at the planning stage, information may be obtained from the facility client and from
architects, interior/landscape designers, engineers and other professionals with knowledge relevant to the
current task. Where the facility is already in use, additional information can be obtained by consulting with:
a) a) potential users of a location plan;
b) b) local police, shopkeepers, reception/information desk staff and others who can have
experience of wayfinding issues within the area to be covered; and
c) c) any existing location plans.
NOTE A site visit can be useful in gaining information regarding the site and its requirements, and, where possible,
to observe and document relevant behavioural patterns.
At the conclusion, the data gathered should be reconciled with the brief.
5.3 Area to be covered
The area to be covered by a location plan will often have logical boundaries, for example as defined by a floor
of a building or by a discrete local geographical area; however, in some circumstances this area may be large
or complex. The area covered by an individual location plan should not be such that it becomes difficult for
users to remember sufficient detail to reliably reach any location shown. In such circumstances, the area
should be divided into smaller units, each with its own location plan. Design consistency should be such that
users can easily recognize the family relationship.
5.4 Information to be shown
Examples of location-plan layouts are shown in Annex AAnnex A.
Some considerations to determine the information to be shown are as follows.
a) a) The location of the users and the types and positions of the facilities about which they will
require information. See Figure A.1Figure A.1.
ISO/PRF 28564-1:2026(en)
b) b) The proportion of the expected users for whom the use of the official local language(s) can be
insufficient.
c) c) Whether the location plan will need to show only specific information, for example, the
locations of different transportation stops. See Figure A.2Figure A.2.

6.1 Principles
The following should be taken into account in the design of a location plan.
a) a) The relevant information from sources described in Clause 5Clause 5.
b) b) It shall consist at least of a title (see 6.26.2),), main body (see 6.36.3)) and, normally, a legend
(see 6.46.4).). It may also include an index (see 6.56.5),), a scale (see 6.66.6)) and a north designator.
c) c) The use of text on the main body should be kept to a minimum.
d) d) The use of the official local language(s) can be sufficient. It is recommended that, if an
additional language is required, English should be used first.
e) e) When using text, jargon should be avoided and specialized terms should only be used where
the target audience is known to be familiar with them. Abbreviations should only be used where they are
in common use and well understood.

p) p) High contrast and other graphic techniques, such as appropriate spacing and scaling, should be
used to ensure legibility under all normal viewing conditions.
q) q) Where fine detail is required, it can be appropriate to incorporate an enlarged view of a specific
area. See Figure A.4Figure A.4.
r) r) On smaller-scale location plans intended to show local detail, all routes accessible by those
with mobility or other physical difficulty should be clearly shown. Where routes might not be fully
accessible, such as where there are steps, this should be indicated and alternative routes, for example, via
slopes or elevators/lifts, should be clearly shown.
s) s) Standardized graphical symbols should be used, where possible, to reduce the amount of text
required.
6.2 Title
The text in a title shall reflect the nature and purpose of the information covered by a location plan through
the choice of a suitable name, for example, “Town-Centre Area Location Plan”, “Newtown Information”. Where
the information is of a general nature, the standardized symbol for Information (ISO 7001, symbol PI PF 001)
should be used. Other graphical symbols may be incorporated where the information is specific. For example,
a bus symbol may be appropriate to draw attention to a bus-stop location plan.
