Detection of Forest Clear-Cuts with Shuttle Radar Topography Mission (SRTM) and Tandem-X InSAR Data
The aim of this study was to determine whether forest clear-cuts during 2000–2011 could be detected as a decrease in surface height by combining Digital Surface Models (DSMs) from the Shuttle Radar Topography Mission (SRTM) and Tandem-X, and to evaluate the performance of this method using SRTM Xand C-band data as references representing the heights before logging. The study area was located in...
متن کاملStatus of TanDEM-X DEM Calibration and Mosaicking towards the TanDEM-X DEM
With begin of 2013 DEM production started with the generation of the Intermediate TanDEM-X DEM (IDEM) for selected science and commercial test sites. This paper gives an overview of the Intermediate DEM production that took place from end of 2012 until July 2013. It describes the DEM production process and the lessons learnt by the IDEM phase. Since autumn 2013 the final DEM generation has begu...
متن کاملCoherence Evaluation of TanDEM-X Interferometric Data
The TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) mission comprises two nearly identical satellites: TerraSAR-X (TSX, launched in 2007), and TanDEM-X (TDX, launched in June 2010). The primary objective of the mission is to generate a worldwide and consistent digital elevation model (DEM) with an unprecedented accuracy. During the first three months after its launch, the TDX sat...
متن کاملEvaluation of Insar Dem from High-resolution Spaceborne Sar Data
In recent years a new generation of high-resolution SAR satellites became operational like the Canadian Radarsat-2, the Italian Cosmo/Skymed, and the German TerraSAR-X systems. The spatial resolution of such devices achieves the meter domain or even below. Key products derived from remote sensing imagery are Digital Elevation Models (DEM). Based on SAR data various techniques can be applied for...
متن کاملPrecise Global Dem Generation by Alos Prism
The Japan Aerospace Exploration Agency (JAXA) generated the global digital elevation/surface model (DEM/DSM) and orthorectified image (ORI) using the archived data of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”), which was operated from 2006 to 2011. PRISM consisted of three panchromatic radiometer...
