Gis-aided Per-segment Scene Analysis of Multi-temporal Spaceborne Sar Series with Application to Urban Areas
نویسندگان
چکیده
It is well known that multi-temporal series of SAR data are able to provide interesting clues about temporal evolution of some land covers. In this work, a per-segment approach based on the use of ancillary Geographic Information System data is proposed. Two test cases show the effectiveness of the technique and its usefulness for quickly detecting changes in urban areas and discriminating to some extent different urban dynamics.

Multitemporal Spaceborne SAR Data for Change Detection in Urban Areas: A Case Study in Shanghai
The objective of this research is to perform automatic change detection within urban areas using multitemporal spaceborne SAR data in Shanghai. Two scenes of ENVISAT ASAR C-VV images were acquired in September, 2008 and one scene of ERS-2 SAR C-VV image was acquired in September, 1999. A generalized version of Kittler Illingworth minimum-error thresholding algorithm, that takes into account the...
متن کاملUrban Monitoring by 4D Change Detection Using Multi-temporal SAR Images
The continuous rise in population and economic growth has led to frequent urban changes such as construction. Monitoring such changes is important for city management, urban planning, updating of cadastral maps, etc. In contrast to conventional field surveys, which are usually expensive and slow, remote sensing techniques are fast and cost-effective alternatives. Spaceborne synthetic aperture r...

With the launch of the German TerraSAR-X system in June 2007, a new generation of high-resolution spaceborne Synthetic Aperture Radar (SAR) data is available; which facilitates a spatially and thematically detailed SAR scene analysis. In fact, the high resolution of TerraSAR-X enables scene on land cover, such as urban areas, deserts, forests and fields, to be accurately mapped. Among the sever...

The Permanent Scatterers (PS) technique, developed by the authors during the last three years, allows the identification of radar targets particularly suitable for SAR interferometric measurements. In fact, despite its remarkable potential, spaceborne SAR Differential Interferometry (DInSAR) has not been fully exploited as a reference tool for ground deformation monitoring, due to the presence ...
متن کاملUtilization of Lidar Dem for Sar Image Analysis in Dense Urban Areas
The increasing resolution of SAR data opens the possibility to utilise this data for scene interpretation in urban areas. Different SAR specific phenomena like foreshortening, layover, shadow and multipath-propagation burden the interpretation. For many urban areas detailed additional information is available which can support both the mission planning and the analysis of the acquired SAR data ...
