Urban Change Pattern Exploration Using Fine-resolution SAR of Ascending and Descending Orbits

摘要

In the last few decades, worldwide urbanization has promoted the emergence of megacities, megalopolises, urban clusters or large urban aggregations. It brings greater global challenges and climatic, environmental, socio-economical issues. Thanks to advanced remote sensing technologies, the necessary and urgent need to monitor urban changes can be performed by using multi-temporal and spatially fine-resolution data of increasing availability. In this paper, exploiting fine-resolution SAR of ascending and descending orbit over urban areas, multi-pattern changes are mapped by means of a novel cascade clustering technique and visualized/interpreted by means of a change vector analysis.
