The interpretation of airphotographs in scale 1: 40,000 offers information for a lot of subjects. It presents generality 
without many details and provides significant understanding - familiarization of corresponding configurations in satellite 
images. 
3 CONCLUSIONS - DISCUSSION 
Remote Sensing data (satellite images and airphotographs) can offer qualitative and quantitative information if they are 
suitably studied and processed. The aspect of using them by various users of different knowledge-experience and 
instrumentation is continously spread. 
In this paper, we search through the possibility of image interpetation (satellite images, airphotographs) by the user- 
Civil Engineer on subjects of his activities. 
The interpretation of satellite images shows that interesting information can be acquired relatively to relief, geological- 
geotechnical subjects and land uses. The term «recognition» in the case of interpretation of a single satellite image has 
not the same meaning with the case of stereoscopic interpretation of images. It is based on the effort to observe tonal 
characteristics, linear and areal configurations, correspondence with other data as maps and continously increasing 
experience. 
The interpretation of airphotographs offers multiple information relatively to watersheds, drainage, faults, rocks, alluvial 
deposits, forest areas, vegetation, cultivated land, roads, lakes, built-up areas. 
The combination of interpreting satellite images and airphotographs in relatively small scale proves to be valuable for 
the acquisition and exploitation of remote sensing information. The study for every area of interest can be further 
extended for satellite images to various subjects of digital analysis and for airphotographs to photogrammetric process in 
the same or larger scale. In this way, the study of geotechnical, hydrological etc subjects and consequently the 
development can be effectively served.
