Crop Classification with Multitemporal Polarimetric Sar Data
Multitemporal measurements gathered by EMISAR over the Foulum (Jutland) test site and AirSAR over the Wageningen test site provide an unrivalled opportunity to examine the factors affecting classification of northern European agricultural crops using both polarimetric and multitemporal information. Data analysis, guided by physical principles, has been used to investigate those polarimetric fea...
متن کاملFlood hazard zones using 2d hydrodynamic modeling and remote sensing approaches
Increasing frequency and severity of flooding demands identification of flood hazard zones in Kalilangan, Bukidnon in response to the echoing need of better disaster preparedness via enhancing the understanding and awareness of the public on flood characteristics by integrating the use of two-dimensional hydrodynamic modeling and remote sensing. Flood simulation was carried out in a two-dimensi...
متن کاملFlood Monitoring from SAR Data
Abstract This paper presents the intelligent techniques approach for flood monitoring using Synthetic Aperture Radar (SAR) satellite images. We applied artificial neural networks and Self-Organizing Kohonen Maps (SOMs), to SAR image segmentation and classification. Our approach was used to process data from different SAR satellite instruments (ERS-2/SAR, ENVISAT/ASAR, RADARSAT-1/2) for differen...
متن کاملAnalysing multitemporal SAR images
Applications of multitemporal SAR data in many cases require accurate estimates of the backscattering coefficient at each time. Here we describe how multitemporal and spatial filtering can be combined in a processing chain to greatly improve the radiometric accuracy of the data and how the general methods can be simplified in the case of ERS data. The results will be illustrated using ERS-2 ima...
متن کاملMultitemporal SAR Image Compression
In this paper, we propose a new method for compressing with loss temporal series of SAR images. The algorithm requires a reference scene used as an input in the compression process. The compression is achieved through aane transformations, comparable to the ones used in fractal coding, but applied here in a non-convergent way. Blocks in the image to be compressed are deened by a non-overlapping...
