LAND COVER MAPPING USING SENTINEL-1 SAR DATA
Sentinel-1A Synthetic Aperture Radar Land cover classification Support Vector Machines Istanbul Turkey
2016/11/24
In this paper, the potential of using free-of-charge Sentinel-1 Synthetic Aperture Radar (SAR) imagery for land cover mapping in urban areas is investigated. To this aim, we use dual-pol (VV+VH) Inter...
UNSUPERVISED CLASSIFICATION OF POLARIMETRIC SAR DATA USING IMAGE CLUSTERING AND H/A/α DECOMPOSITION
Image Classification Data Clustering H/A/a Polarimetric SAR Iteration POLSARPRO
2016/3/17
This paper proposed a method of unsupervised classification of polarimetric SAR data based on image clustering and H/A/a decomposition. Fully polarimetric L band data collected by ALOS PALSAR system w...
A PROBABILISTIC FUSION STRATEGY APPLIED TO ROAD EXTRACTION FROM MULTI-ASPECT SAR DATA
SAR road extraction multi-aspect images fusion
2015/8/28
In this paper, we describe an extension of an automatic road extraction procedure developed for single SAR images towards multiaspect SAR images. Extracted information from multi-aspect SAR images is ...
POTENTIAL OF BUILDING EXTRACTION FROM MULTI-ASPECT HIGH-RESOLUTION AMPLITUDE SAR DATA
SAR Building Detection Reconstruction Urban GIS Fusion
2015/8/7
State-of-the-art airborne SAR sensors provide spatial resolution on the order of a decimetre. In such data, many features of urban objects can be identified, which were beyond the scope of radar remot...
INTERPRETATION OF HIGH RESOLUTION SAR DATA USING EXISTING GIS DATA IN URBAN AREAS
SAR Registration Simulation Georeferencing GIS Change Detection Urban Building
2015/8/7
Within the paper the automatic matching of existing GIS data to airborne SAR scenes for georeferencing is discussed. For this purpose simulated SAR images are generated based on the available GIS obje...
