ABSTRACT
The ISO 9000 rules, which have introduced the “Quality System” for the production of goods and services, have been
taken up by the more industrialised countries with the objective of assuring the level of necessary prerequisites through
control procedures and eventual corrective action during the work cycle.
In the field of numeric cartography, the approach according to standards of quality includes all the stages: design and
drawing up of specifications, flight, photogrammetric imaging, acquisition of the photographs, positioning, contouring,
printing and final inspection.
Applying a series of programmed “on line” checks to the production cycle, according to the fundamental principles
introduced by the Quality rules, assures the achievement of the required specifications, while not waiting for the final
inspection phase for verification that could come too late.
In this paper we review the guidelines of the ISO 9000 publications and we analyse some critical aspects of the
production cycle.
1. INTRODUCTION
The ISO 9000 legislation that has introduced the
“Quality System”, parallel to the extension of the market
towards greater and more international dealings, has
changed the strategies for production and the
development of companies.
The creation of a company policy aimed at the
production of a “Quality System” requires a new
organization of work in the company, which starts at the
managerial level and includes all those who take part in
the production process.
In particular, it is important to guarantee that the
product or service that is provided satisfies the needs
that are expressed or implied by the client, in order to
create trust both inside and outside the company, be it
public or private.
In the area of numeric map making using
aerophotogrammetric pictures, the management of the
quality involves all the construction phases: the project,
realization, testing.
To subject the production cycle of map making to a
series of “on-line” programmed checks, according to
the fundamental principles of the legislation, assures
the fulfillment of the specific requests.
This aspect is particularly important for the production
cycle under examination, in as much as the traditional
methods of testing can lead to a late recognition of
errors that cannot be modified and therefore prejudice
the correctness of the map.
2. REQUISITES FOR A QUALITY SYSTEM
ISO 8402 defines system quality as the organizational
structure, the responsibility, the procedures, the
processes undertaken for the management of the
company for quality.
From this definition it is clear that quality is not referred
only to products/services, but to the entire management
and control of the activities present in the company, by
which the production of the product is reached.
The legislation of the ISO 9000 family (figurel) give the
principle rules both for the definition of a quality system
and for its relative application, giving a guide to the
management of quality and the general requisites for
guaranteeing it.
In particular, the ISO 9000-1 is the instrument for the
approach to the whole legislative packet, in as much
as:
• It clarifies the principal concepts connected to
quality and the relative distinctions and
interrelations;
• It gives a guide for the choice and use of the ISO
9000 legislative family for a correct running of the
company for quality.
In general the creation of a System Quality is a
complex process and aimed at the improvement of the
level of a product or service, and it develops through
the phases of: plan; do, check, and act, following the so
called Shewart cycle or Deming’s ring.
All this can be translated in the creation of a quality
plan, that, in relation to the product/service, establishes
the operating methodology, resources and the
sequence of activities that influence the quality of the
product. In particular the plan defines:
• The objectives of quality to carry out;
• Distribution of responsibility;
• The procedures and the work instructions to apply;
• Control methodology.
At the same time a “Quality Manual” is created that
illustrates the quality program of the company and the
criteria to establish it, therefore becoming an
instrument of presentation for the company to the
outside world.
