Caspian Sea Fluctuations are periodic which are caused by
various natural factors. In the situation of Caspian Sea
level decrease, marine costal constructions become unutilized and in case of Caspian Sea level increase, the dry land territories are
being flooded what causes destroy of infrastructure. It is very important to
make correct planning of future coastal infrastructure and prediction of
possible accidents. To realize these goals it is inevitable to make appropriate
reliable methodlogy working with accurate technological principles and
supporting decision makers in their everyday activities related with the
sustainable development of coastal zones. But it is very important to define
all possible spatial data sources suitable for safe navigation, coastal
resource management, coastal environmental protection and sustainable coastal
development. In this article was researched one of the reliable data sources as
high-resolution satellite imagery which can be compared with the aerial
photography which was always suitable for the purposes of the coastal
management. But taking into account the fact that the Caspian Sea Fluctuation
impacts on the costal area are periodic and significant it is necessary to
select the source of data that can be easily and more periodically obtained as
high-resolution satellite imagery. The
main objective of this research is to present the up-to-date developed method
of how to predict the Caspian Sea Level fluctuation impacts on the coastal
areas by monitoring visually results of GIS processing analysis based on the
accurate spatial data acquired from high-resolution stereo satellite
imagery. The results of this research
present that the processing of high-resolution stereo satellite imagery and
prepared precise stereo model, digital terrain models and digital orthophotos
are absolutely suitable for the environmental modeling of potential Caspian Sea level fluctuations. It assumes that it is
possible to transform this photogrammetric methodology into the technological
form usefull for the decision makers and all other parties involved in the
activities related with the coastal management. High-resolution stereo
satellite imagery satisfy the needs of coastal environmental management giving
almost the same results as aerial photography. Nowadays acquisition of
satellite imagery is easily accessible periodically giving possibility for the
permanent tracking of coastal line change dynamics. Using the advantages of
high-resolution satellite imagery it is possible to extract majority of all
topographical details along the coastal areas and over whole territory using
stereo plotting techniques important for the further GIS modeling of Caspian Sea possible level fluctuation impacts to coastal
areas.
