Commission VI
ABSTRACT:
Italian contributions to research on subjects covered by ISPRS Commission III have been provided both
by traditional photogrammetrists and relative newcomers, like experts in electronics and computer
vision. The research group of photogrammetrists most involved in Commission III activities is that of the
Politecnico di Milano.
1. INTRODUCTION
This paper tries to give an overview of Italian activities in
the period 1988-1992 for the field covered by ISPRS
Commission III. At the end of the article, a list is given of
publications, prepared at Italian research establishments,
for the mentioned field and mentioned time period. In
order to restrict the list to publications of possible interest
to the international community, papers written in Italian
are excluded.
The preparation of this report is a difficult task, because
the number of active research groups is very large. They are
mostly small and scattered along different departments and
institutes of different.research establishments. Besides, a
significant number papers are published outside the
traditional photogrammetric information channels. The list
can therefore only be indicative.
2. RESEARCH OF TRADITIONAL
PHOTOGRAMMETRISTS
The traditional photogrammetric experts are organized in
the SIFET, the Italian national organisation for
photogrammetry and surveying (Società Italiana di
Fotogrammetria e Topografia). Its task is to give a
contribution to the study of and research in
photogrammetry and surveying. It resides at the same
adress as the author. The SIFET publishes a trimestral
bulletin with papers of national interest written in Italian
and organises an annual congress. The most active
members of the SIFET are the Institutes for Surveying and
Photogrammetry of the various Universities. However, the
majority of efforts are directed towards application based
activities. In the period of 1988 - 1992 areas of special
interest were support of GPS to photogrammetry, digital
image processing for industrial and architectural
photogrammetry and creation of a GIS by digitizing maps.

Unfortunately research in the field covered by Commission
III is limited. Traditionally, the research group most
interested in Commission III activities is that of the
Politecnico di Milano; with this group collaborate a number
of researchers in other establishments. In addition to
traditional fields like block adjustments and surface
reconstruction new topics were studied, like
aerotriangulation with SPOT imagery and automated DEM
production from digital images. At the moment, research
on digital image processing algorithms is shifting from
small scale SPOT imagery to the larger scale imagery of
close range photogrammetry. Topics of interest and of
probable future research are the combination of
aerotriangulation and aircraft trajectory reconstruction with
GPS data, and GIS data structures.
Besides the SIFET, a second organisation in the field is the
AIT (Associazione Italiana del Telerilevamento), which is
active in the field of remote sensing (Commission VII).
3. RESEARCH OF OTHERS
With the traditional photogrammetric experts involved
primarily with direct applications, the sector of data
analysis and mathematical modelling is to some extent
neglected. This provides an opportunity for newcomers like
experts in electronics and computer vision. In fact, from
these fields, significant contributions have been made.
Areas of special interest were processing of satellite
imagery and computer vision.
4. CONGRESSES
At Centre for International Mechanic Studies in Udine,
each year an advanced school is held with renowned
international speakers on topics regarding surveying and
photogrammetry. The topics in the year between 1988 and
199
