by a geologist, that is the interpretation is to be fulfilled in
the interactive regime. Here, the development and application of
hybrid systems are very important, which will make it possible to
carry out both various optical-electronic transformations and iden-
tification of objects on the basis of the analysis of images and
revealing the informative features as well as to construct maps
and graphs.
It is obvious that capabilities of the aerial photographic
technique have not been so far exhausted and its further develop-
ment depends on the acquisition of new information important for
solving different geological problems by special-purpose aerial
photographic survey and data processing on the basis of modern
scientific and technical achievements.
Photographic images of the Earth obtained from gpace contain
qualitatively new information on the geological structure of the
Earth, the spatial distribution of natural resources, the dynamics
of natural processes, its meteorologic conditions, the deteriora-
tion of natural environment and on other phenomena taking place
either on land or in off-shore areas.
Due to the great areal coverage and high natural generalization
of space images, their application has greatly contributed to the
study of the geological structure of major regions. So, images ob-
tained from various space vehicles launched in the USSR and pre-
senting a new tool of the study of our vast territory are,nowadays,
broadly applied to geology, as a science, and to geological survey,
as a branch of the national economy.
Different techniques have been elaborated to study platform
and folded regions, those of geomorphological and geological in-
terpretation and transformation of space images in any cartogra-
phic projection on the basis of computers and modern transformation
instruments.
Due to the generalization, space images exhibit major geologi-
cal objects which are frequently deep-seated and provide new geolo-
gical information on deep horizons of the Earth's crust.
Space images are particularly important for the study of tec-
tonics of large regions. They have made itpossible to assess the
important role, much more important than it was expected, of ring
siructures in the structural pattern of regions, their relation
to linear faults and the relationships of structures of different
types and sizes.
Transcontinental faults and fault zones identified from space
images provide & new insight into the structure of the Earth's
crust and the stages of its evolution. Some major ring structures
revealed within ancient shields are interpreted by many geologists
as relics of the most ancient (lunar) stage of the Earth evolution,
what is also suggested by field geological and geochemical data.
Space imagery help reveal aulacogens, rifts and major faults
