Observations from Earth's remote sensing satellites have been a promising tool for studies on land cover and its changes, and related environmental phenomena. In this study, we demonstrate two environmental related land cover classification applications using integrated methods that involve multiple passive and active remote sensing sensors onboard different satellites, including Landsat Thematic Mapper (TM) and other optical/infrared imageries, synthetic aperture radar (SAR) system such as the Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard of the Advanced Land Observing Satellite (ALOS), and radar altimeters such as the Environmental Satellite (ENVISAT), etc.

520 $a Observations from Earth's remote sensing satellites have been a promising tool for studies on land cover and its changes, and related environmental phenomena. In this study, we demonstrate two environmental related land cover classification applications using integrated methods that involve multiple passive and active remote sensing sensors onboard different satellites, including Landsat Thematic Mapper (TM) and other optical/infrared imageries, synthetic aperture radar (SAR) system such as the Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard of the Advanced Land Observing Satellite (ALOS), and radar altimeters such as the Environmental Satellite (ENVISAT), etc.
520 $a Firstly, we did a case study in Geladandong glacier of classifying and obtaining the rock/glacier boundary using Landsat data as well as integrated SAR methods, including polarimetric SAR classification and repeat pass SAR correlation coefficients technique. Over 40 years, the shrinkage of the glacier was observed from the results of analyzing and classifying Landsat series data. The estimated retreating rates are 0.148 km2/year and 0.134 km2/year in region B and C of Geladandong glacier during 1973&sim;2014. The Randolph Glacier Inventory (RGI) 4.0 does not provide this dynamic changing of the glacier extent. Moreover, considerable biases have also been observed in several regions.
520 $a To further strengthen the finding, we employed SAR and polarimetric SAR data by applying correlation coefficient calculation and polarimetric SAR decomposition and segmentation. The results were consistent with those from Landsat classification in every particular small glacier region.
520 $a Secondly, data from multiple satellite sensors, including Landsat series, ALOS-1 PALSAR Synthetic Aperture Radar and ENVISAT altimeter are employed for the purpose of analyzing the water extent in polder regions and its changing trend in last 40 years and of surveying the impact on polder embankments caused by erosion and sedimentation. In Polder 14, the surface elevation was approximately 30 centimeters higher in May than in August, given by ENVISAT surface elevation data. River channel boundary change in Arpangasia is also investigated. The river channel shape has been changed with approximately 1.4km2 on both sides of the river segment in the past 40 years. In the estuary region Polder 50&sim;57, delta displacement in delta boundaries is observed in the water/land classification results based on Landsat data from 1972 and 2011. Moreover, the results from applying H/A/Alpha Wishart classification algorithm with full polarization SAR data provided more detailed surface types that can help monitoring and estimate the potential flooding risk of the region.
