The research aims at spatial and socio-economic analysis of landscape patterns in Baltic coastal area of Estonia. The process of active suburbanization, which is analyzed in the current work, is caused by complex socio-economical factors which arise from sociopolitical changes since the end of the USSR. Study area encompasses Baltic coastal region of Parnu County. The social-economic triggers causing intensive construction of summer cottages and landscape types were examined. The methodology is based on the socio-economic analysis of suburbanization based on statistical data and mapping of the landscapes. Mapping was performed using GIS, land cover maps and Landsat data. Fieldwork and in-situ observations were performed to detect built- up areas in Parnu surroundings and proved intensive construction residential buildings in Parnu, demonstrating ground changes in immobility system in modern Estonia, which affects landscapes. The results illustrate highly heterogeneous and diverse landscape types in the study area.
