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.
