Built-up Area Extraction from PolSAR Imagery with Model-Based Decomposition and Polarimetric Coherence
Built-up area extraction from polarimetric SAR (PolSAR) imagery has a close relationship with urban planning, disaster management, etc. Since the buildings have complex geometries and may be misclassified as forests due to the significant cross-polarized scattering, built-up area extraction from PolSAR data is still a challenging problem. This paper proposes a new urban extraction method for Po...
متن کاملMonitoring the Built-up Area Transformation Using Urban Index and Normalized Difference Built-up Index Analysis
Makassar is one of the metropolitan cities located in Indonesia which recently experiences massive an increased construction because of population growth. Mapping the spatial distribution and development of the built-up region is the best method that can use as an indicator to set the urban planning policy. The purpose of this study is to identify changes in land use and density in Makassar Cit...
متن کاملSeparation of Built-up Areas Using Polarization Orientation from Polarimetric Sar Images
Polarimetric decomposition and classification are important applications for polarimetric synthetic aperture radar (POLSAR) images. Among many methods developed so far, entropy-anisotropy-alpha classification [1] and three component decomposition [2] are most popular. In an urban area analysis, it is found that the polarimetric analysis has a problem to identify built-up areas. With the three c...
متن کاملRoad Extraction from Multi-frequency and Polarimetric Sar Imagery
Automatic extraction of linear topographic objects, such as, roads, rivers, or power lines, is an important topic for topographic mapping. In case of roads, an automatic extraction from Synthetic Aperture Radar (SAR) imagery is rather difficult, due to the speckle effect and the limited spatial resolution in relation to the road width. In this paper we investigate the additional use of multifre...
متن کاملAnalysis of Built-Up Areas from Polarimetric Interferometric SAR Images
This paper describes the analysis of built-up areas using fully polarimetric interferometric SAR data at L-band. This approach uses a polarimetric interferometric segmentation to determine the number of dominant scattering mechanisms required by an interferometric phase estimation using ESPRIT method.
