ABSTRACT
In this paper, the possibilities of visual interpretation of a single image (Landsat and Spot) and of stereoscopic
interpetation of airphotographs in small scale are being searched through. This is done from the point of «collecting»
information that interest civil engineers for development subjects. :
The combination of interpretation of satellite image and airphotographs seems to offer interesting information relatively
to drainage, roads, faults etc. It can be considered as a starting-point and a reference base for further photogrammetric
and geoinformation procedures and digital analysis.
1 INTRODUCTION
Remote Sensing gains continously increasing number of users, because of the fast progress in methods and
instrumentation. These users may concern different professions, occupations, services etc., presenting significant
particularities, locally and temporally.
The civil engineer is an important division of users, because of his main scientific and professional activities (Dept of
Civil Engineers, 1999).
The term «development» presents multiple considerations (Zuidam R.A. et al, 1979), that are significantly related to the
activities of civil engineer.
The above describe the framework of this paper.
We mainly deal with remote sensing (satellite images and airphotographs) and particularly with visual interpretation of a
single image for satellite images and stereoscopic images for airphotographs (Cracknell A.P. 1991, Meijerink A.M.J.
1987, Verstappen H.Th. 1977). The results of this visual interpetation can further support photogrammetric and
geoinformation process.
Sithonia Peninsula in Northern Greece is the example area.

2 INTERPETATION OF SATELLITE IMAGES (LANDSAT - SPOT) AND AIRPHOTOGRAPHS
The data we used, concerned Sithonia Peninsula. They included
Satellite images: Landsat TM 1998-07-26 (bands 1-7), Spot PAN 1993-08-26, Spot XS 1992-08-12 (3 spectral bands)
Airphotographs in scale 1: 40,000.
Image interpetation took place with simultaneous reference to corresponding topographic, geologic and other thematic
maps in various scales.
