Amplitude Change Detection with ENVISAT ASAR to Image the Cultural Landscape of the Nasca Region Peru Francesca Cigna British Geological Survey Natural Environment Research Council Nicker Hill Keyworth Nottingham NG12 5GG United Kingdom Search for more papers by this author 2015-1-15This research aims at differentiating human-induced effects over the landscape from the natural ones by exploiting a combination of amplitude and phase changes in satellite radar images At a first step ERS and Envisat data stacks are processed using COS software developed by the company SARMAP Various features related to amplitude and phase as well as to their changes are then

Remote sensing techniques for flood monitoring

Flooding is the most common natural disaster and can occur anywhere Flash floods may be caused by heavy rainfall levee breaches or dam failures For the extraction of data of flooded areas pre and post event ENVISAT ASAR satellite images were analyzed This work may be helpful to policy makers for immediate assessment of flood risk and damage

2015-3-20The main advantage of radar techniques compared to optical ones is its ability to operate during the night as well as through clouds These two radar properties are very important in areas with frequent cloud cover as is the case for many glacier regions and in polar regions where long periods of the year are totally dark because of the absence of the Sun (polar nights)

CiteSeerX - Document Details (Isaac Councill Lee Giles Pradeep Teregowda): ERS-1 and ASAR imagery were used for mapping and monitoring the forest area of French Guiana for 1992/1993 2003/2004 and 2006/2007 Imagery was ortho-rectified using the SRTM DEM A least square algorithm was used to improve the residual geometric inaccuracies For the ERS data significantly better

2010-6-11ENVISAT ASAR scenes acquired bi-monthly from June 2005 to August 2006 The reservoir surface areas were determined with a quasi-manual classification approach as stringent classification rules often failed due to the spatial and temporal variability of

2010-11-4reeds Nico et al [14] compare flood detection from amplitude change detection to coherence methods from multipass SAR data Horrit et al [15] use a statistical active contour model to delineate flood boundaries and Heremans et al [16] compare flood delineation results from and active contour model to that of an object-oriented

In this paper we conducted damage identification for Yingxiu town and its adjacent areas with ENVISAT ASAR as data source using amplitude of multi- temporal radar data and phase information The ratio change detection using pre- and post-earthquake amplitude images yielded satisfying results in Yingxiu town and Zipingpu reservoir

This study aims to aim to investigate the capability of ENVISAT ASAR satellite and Google Earth data for three-dimensional (3-D) slum urban reconstruction in developed country such as Egypt The main objective of this work is to utilize 3-D automatic detection algorithm for urban slum in ENVISAT ASAR and Google Erath images were acquired in

Amplitude Change Detection with ENVISAT ASAR to Image the Cultural Landscape of the Nasca Region Peru Archaeological Prospection 21 maggio 2013 Synthetic aperture radar (SAR) amplitude information from ENVISAT C-band advanced SAR (ASAR) data was used to analyse the cultural landscape of the Nasca region southern Peru

Abstract: Preliminary results are reported on ship detection using coherence images computed from cross-correlating images of multi-look-processed dual-polarization data of ENVISAT ASAR The traditional techniques of ship detection by radars such as CFAR (Constant False Alarm Rate) rely on the amplitude data and therefore the detection tends to become difficult when the amplitudes of ships

Abstract In this study damage caused by Typhoon Haiyan in the city of Tacloban Philippines is extracted from COSMO-SkyMed imagery data A multitemporal correlation map i e a color composite of the backscattering coefficients obtained on different days and their correlation coefficients is used to indicate changes

[PDF] CHANGE DETECTION BY INTERFEROMETRIC

Two interferometric pairs of Synthetic Aperture Radar (SAR) images are used to generate coherence images of the Nasca Lines Pampa area The first coherence image is based on a pair of ERS-2 SAR data from 1997 and 1999 the second one is computed from two ENVISAT-ASAR (Advanced SAR) images from 2003 and 2004 The main objective is to study the changes in the coherence values in different
