Monitoring Temperate Glacier : Combined Use of Multi-date Terrasar-x Images and Continuous Gps Measurements
نویسندگان
چکیده
This paper highlights the contribution of TerraSAR-X (TSX) High Resolution (HR) images for temperate glacier monitoring. A series of 14 images have been acquired since October 2007 on the Mont-Blanc test area. This area involves well-known temperate glaciers which have been monitored and instrumented ("stick" for annual displacement/ablation, GPS, cavitometer for basal displacement...) for more than 50 years. The combined use of insitu measurements and multi-temporal images allows to improve the potential of HR SAR measurements. Interpretation of HR images, investigation of interferometric and correlation methods, and the first glacier displacement results are presented.

Monitoring Alpine glacier activity by a combined use of TerraSAR-X images and continuous GPS measurements – the Argentière glacier experiment
The monitoring of Alpine glacier activity is one of the applications which require the combined use of ground measurements and SAR data. It should become feasible thanks to the new generation SAR satellites (ALOS, TerraSAR-X, Cosmo-SkyMed and RadarSAT-2) and the high precision GPS measurements. This paper presents the early results of an experiment which started in 2007 on Argentière glacier (M...
متن کاملMonitoring Temperate Glacier with High Resolution Automated Digital Cameras – Application to the Argentière Glacier
In the context of global warming, the monitoring of temperate glaciers is an important issue for economical and security reasons (water and energy resources, falling ice...) and climate change monitoring. In the glaciologist community this monitoring is based on ground measurements yielding specific information about mass-balance and ice flow. Unfortunately the daily variation measurements of t...
متن کاملSemi-Automated Monitoring of a Mega-Scale Beach Nourishment Using High-Resolution TerraSAR-X Satellite Data
This paper presents a semi-automated approach to detecting coastal shoreline change with high spatialand temporal-resolution using X-band synthetic aperture radar (SAR) data. The method was applied at the Sand Motor, a “mega-scale” beach nourishment project in the Netherlands. Natural processes, like waves, wind, and tides, gradually distribute the highly concentrated sand to adjacent beaches. ...
متن کاملCentimeter Range Measurement Using Amplitude Data of Terrasar-x Imagery
The SAR (Synthetic Aperture Radar) imagery are largely used for the environmental, structures and infrastructures monitoring. In particular, Differential SAR Interferometry (DInSAR) is a well known technique that allows producing spatially dense displacement maps with centimetre to millimetre accuracy. The SAR signal is characterized by phase and amplitude value and the DInSAR remote sensing te...
متن کاملMulti-Temporal Land-Cover Classification of Agricultural Areas in Two European Regions with High Resolution Spotlight TerraSAR-X Data
Functioning ecosystems offer multiple services for human well-being (e.g., food, freshwater, fiber). Agriculture provides several of these services but also can cause negative impacts. Thus, it is essential to derive up-to-date information about agricultural land use and its change. This paper describes the multi-temporal classification of agricultural land use based on high resolution spotligh...
