Revision of built-up areas in a GIS using satellite imagery and GIS data
GIS Update Small-Scale Image Analysis Texture Linear Feature Point Detection
2016/5/20
In general, built-up areas or populated places are significantly changing within the revision interval of a GIS (Geographic Information System) or map. In this paper we present a method by means of wh...
DETECTION OF BUILT-UP AREAS USING POLARIMETRIC SYNTHETIC APERTURE RADAR DATA AND HYPERSPECTRAL IMAGE
Polarimetric synthetic aperture radar polarimetric target decomposition hyperspectral image target detection correlation coefficient
2016/1/15
Polarimetric synthetic aperture radar (POLSAR) is an advantageous data for information extraction about objects and structures by using the wave scattering and polarization properties. Hyperspectral r...
Comparison of Pixel-based and Object-oriented Classification Methods for Extracting Built-up Areas in Aridzone
Remote Sensing Change Detection Built-Up Area Expansion Object-Oriented Classification
2015/10/12
This study focuses on the comparison between the classical and object-oriented image classifications of remote sensing imagery in
the arid area. Due to its special geographic environment and socio-e...

EXTRACTING BUILT-UP AREAS FROM MULTITEMPORAL INTERFEROMETRIC SAR IMAGES
Land Use Urban SAR Segmentation Classification
2015/3/24
Automatic extraction of built-up areas from a multitemporal interferometric ERS-1/2 Tandem SAR dataset was studied. The image
data were segmented into homogeneous regions and the regions were classi...
