“…However, because the dense cloud cover in Maritime Antarctica limits the application of optical sensors, microwave sensors are usually the most appropriate option (Mora et al, 2013). The use of Synthetic Aperture Radar (SAR) data has been implemented within the Antarctic region in many studies (Engeset and Weydahl, 1998;Jezek, 1999;Jezek et al, 2003;Koch et al, 2008;Schmid et al, 2012) and surface mapping has been carried out with data obtained from the space-borne ALOS PALSAR, RADARSAT-2 and TerraSAR X (Koch et al, 2008(Koch et al, , 2009Schmid et al, 2012Schmid et al, , 2015Guillaso et al, 2015).…”

“…Research work has been published to illustrate the surface mapping capabilities of RADARSAT-2 and its potential for global exploration applications within the Antarctic region (Scheuchl et al, 2012;Schmid et al, 2012). This has also been shown by the RADARSAT-2 Antarctica mosaic that was acquired during 2008 (Hillman et al, 2011).…”

Geomorphological mapping of ice-free areas using polarimetric RADARSAT-2 data on Fildes Peninsula and Ardley Island, Antarctica

International audienceSatellite-borne Synthetic Aperture Radar (SAR) has been used for characterizing and mapping in two relevant ice-free areas in the South Shetland Islands. The objective has been to identify and characterize land surface covers that mainly include periglacial and glacial landforms, using fully polarimetric SAR C band RADARSAT-2 data, on Fildes Peninsula that forms part of King George Island, and Ardley Island. Polarimetric parameters obtained from the SAR data, a selection of field based training and validation sites and a supervised classification approach, using the support vector machine were chosen to determine the spatial distribution of the different landforms. Eight periglacial and glacial landforms were characterized according to their scattering mechanisms using a set of 48 polarimetric parameters. The mapping of the most representative surface covers included colluvial deposits, stone fields and pavements, patterned grounds, glacial till and rock outcrops, lakes and glacier ice. The overall accuracy of the results was estimated at 81%, a significant value when mapping areas that are within isolated regions where access is limited. Periglacial surface covers such as stone fields and pavements occupy 25% and patterned grounds over 20% of the ice-free areas. These are results that form the basis for an extensive monitoring of the ice-free areas throughout the northern Antarctic Peninsula region

ABSTRACT:In this paper, we describe a new approach to analyse and quantify land surface covers on Deception Island, a volcanic island located in the Northern Antarctic Peninsula region by means of fully polarimetric RADARSAT-2 (C-Band) SAR image. Data have been filtered by a new polarimetric speckle filter (PolSAR-BLF) that is based on the bilateral filter. This filter is locally adapted to the spatial structure of the image by relying on pixel similarities in both the spatial and the radiometric domains. Thereafter different polarimetric features have been extracted and selected before being geocoded. These polarimetric parameters serve as a basis for a supervised classification using the Support Vector Machine (SVM) classifier. Finally, a map of landform is generated based on the result of the SVM results.
