Abstract
Nowadays, innovative technologies are becoming progressively interlinked with the issue of environmental change. They provide a systematized and objective strategy to document, understand and simulate the change process and its associated drivers. In this context, the main aim of this work is to develop spatial methodologies that can assess the environmental change dynamics and its associated drivers. To achieve this objective, optical multispectral satellite imagery, integrated with field survey data, were used for the analyses. Object Based Image Analysis (OBIA) was applied to assess the change dynamics within the period 1990 to 2014. Broadly, the above-mentioned analyses include: Object Based (OB) classifications; post-classification change detection; data fusion; information extraction; and spatial analysis. The dynamic changes were quantified and spatially located as well as the spatial and contextual relations from adjacent areas were analyzed. The study concludes with a brief assessment of an ‘oriented’ framework, focused on the alarming areas where serious dynamics are located and where urgent plans and interventions are most critical, guided with potential solutions based on the identified driving forces.
