KEY WORDS: Standardization, CEOS, Colour Systems, Quality Management
ABSTRACT:
The paper reviews activities of interest to ISPRS taking place within ISO, CEOS and in colour systems. The ISO activities sum-
marized here concern standards in photography, in optical instrumentation with emphasis on image quality determination, in space
data and information transfer systems and in quality management. The CEOS activities are presented with an emphasis on those
of the WG on Calibration and Validation and its subgroup on Terrain Mapping. A short summary of international activities in
regard to colour ordering systems shows a somewhat unclear situation with a larger number of systems. The paper concludes with
a call for a stronger involvement of ISPRS in those ISO and CEOS activities relevant to ISPRS activities.
KURZFASSUNG:
Der Bericht gibt einen Überblick über für die Internationale Gesellschaft für Photogrammetrie und Fernerkundung (ISPRS) inter-
essante Aktivitäten in der Internationalen Organisation für Normung (ISO), der Organisation der satellitenbetreibenden internatio-
nalen und nationalen Behórden (CEOS) und bezüglich Farbsystemen. Die hier zusammengefaBten ISO-Aktivitáten betreffen die
Normierungsbereiche Photographie, optische Geráte mit Betonung auf die Bestimmung von Bildqualitát, Weltraumdaten und -in-
formationsübertragungssysteme und Qualititsmanagement. Die CEOS-Aktivitáten werden zusammengefaBt mit besonderem Au-
genmerk auf die Tátigkeit der Arbeitsgruppe für Kalibrierung und Validierung und deren Untergruppe, die sich mit der Gelände-
aufnahme (vorrangig der Höhe) befaßt. Der Überblick über die internationalen Bemühungen um eine Normierung von Farbord-
nungssystemen zeigt eine etwas unklare Situation mit dem Ergebnis, daß verschiedene Systeme genutzt werden. Der Bericht
schließt mit der Empfehlung an die ISPRS, sich verstärkt an jenen Tätigkeiten von ISO und CEOS zu beteiligen, die für die Mit-
glieder der Gesellschaft von Bedeutung sind.
1. INTRODUCTION
Technical Commission (TC) I of ISPRS has a history in the
development of standard-type documents, namely a "Recom-
mended Procedures for Calibrating Aerial Cameras and for Re-
lated Optical Tests" and a "Specification for Aerial Survey
Photography". The first document was developed during the
late forties and fifties at a time when international standardiza-
tion in the optical field did not yet take place; this
development represented a major part in the activities of TC I:
It has been repealed awaiting a systematic reworking based on
now existing international standards but is nonetheless still
used as reference document for example in a German
standard.. The second document was developed in the early
eighties and remains in force today although is has proven
difficult to establish the extent of its use.
In recognition of the fact international standardization in the
photographic and optical fields had been established, ISPRS
TC I entered into several and plans to enter into additional
liaison agreements with several Technical Committees (TC's)
of the International Organisation for Standardization (ISO)
thus establishing a mechanism for passive or even active
participation in the development of international standards. A
review will be given of the present situation and of work of
interest taking place in ISO TC 42 (Photography) and several
Subcommittees (SC's) of TC 172 (Optical Instrumentation)
and TC 20 (Aircraft and Space Vehicles). ISO has developed
international standards for quality management (ISO 9000
etc.). These standards are also of interest for the
photogrammetric community, e.g. in connection with the
"Specification for Aerial Survey Photography", and they will
therefore be reviewed as well.
The Committee on Earth Observations (CEOS) is an interna-
tional body with satellite-operating agencies as members. A
previous attempt to gain for ISPRS the status of an "Observing
Member" failed, and a new application should be made. The
CEOS activities are carried out in working groups. Of particu-
lar interest to TC I is Working Group on Calibration and Vali-
dation (WGCV), which has several subgroups, e.g. one for ter-
rain mapping. The WGCV activities of interest to TC I will
also be reviewed. CEOS goes their own way in regard to stan-
dards; this way will be described.
Other standard activities possibly of interest to TC I concern
colour A short review over the situation in colour
standardization will also be given. As this topic was discussed
in a workshop of WG I/1, the workshop results in this and
other topics will be introduced.
2. INTERNATIONAL ORGANIZATION FOR
STANDARDIZATION (ISO)
Standardization takes place on three levels: global, regional
and national. Global agencies are ISO, operating since 1947,
and the International Electrotechnical Commission (IEC),
established 1906. A formal agreement between them states
that standardization in the electrical and electronic fields are
the concern of IEC, all other subjects of ISO. Another
international agency involved with standardization is the
International Telecommunication Union (ITU), established in
