Abstract
Urban land covers (ULC) are essential information for numerous urban studies at various scales, while it remains challenging to obtain accurate and timely ULC information due to many factors, such as land cover diversity, topographic shadows, cloud coverages, etc. Using multi-sensor satellite images is considered a promising approach for improving ULC classification. Synthetic Aperture Radar (SAR), with its polarimetric and interferometric capabilities, has been widely recognized to be able to provide useful information about urban areas as it is sensitive to the electromagnetic and geometric characteristics of urban land surfaces. Numerous studies have been conducted with applications fusing SAR and optical data since the early 1990s with significant progress. This lecture will provide an overview of related issues and their latest progress in integrating SAR and optical data during the monitoring over urban areas. Challenges and related opportunities will also be discussed.
