Evaluation of vertical accuracy of TanDEM-X Digital Elevation Model in Egypt

Egyptian Journal of Remote Sensing and Space Sciences, 2023
The study conducted aimed to examine the accuracy of Digital Elevation Models (DEMs) in Egypt, specifically the TanDEM-X mission's 30 m and 12 m resolution DEMs and the SRTM DEM with a 30 m resolution.

Paddy-Rice Monitoring Using TanDEM-X [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2015
This paper evaluates the potential of spaceborne bistatic interferometric SAR images for the monitoring of biophysical variables in wetlands, with a special interest on paddy rice. The assessment is made during the rice cultivation period, from transplanting to harvesting time (May to October) for fields around Gala lake (Turkey), one of the largest ...

TanDEM-X: Mission Status and Science Activities [PDF]

IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2019
The paper provides an up to date overview of the German TanDEM-X satellite mission status and its ongoing science activities. The global digital elevation model (DEM) of TanDEM-X became available in 2016 and surpassed all expectations: It has 99.9% coverage, 12-m posting, absolute height accuracy of approximately 1 m and a relative height error ...

Terrestrial Impact Craters - the Tandem-X View [PDF]

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In the past years we have exploited the TanDEM-X elevation model for impact crater research. This is the first high-resolution global DEM which permits accessing all confirmed impact structures. We demonstrate that the high horizontal and vertical accuracies, coupled with the dense pixel grid, allow studying the morphologies of simple and complex ...

5meCpG epigenetic marks neighboring a primate-conserved core promoter short tandem repeat indicate X-chromosome inactivation. [PDF]

PLoS ONE, 2014
X-chromosome inactivation (XCI) is the epigenetic transcriptional silencing of an X-chromosome during the early stages of embryonic development in female eutherian mammals.

Interferometric processing algorithms of TanDEM-X data [PDF]

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The purpose of this paper is to provide an algorithmic overview of the interferometric processing embedded in the Integrated TanDEM-X Processor (ITP), settled to the generation of the raw digital elevation model (DEM). The main processing blocks are described, with a focus on the spectral matching of the azimuth spectra, the high-precision ...

Mapping the landscape of tandem repeat variability by targeted long read single molecule sequencing in familial X-linked intellectual disability

BMC Medical Genomics, 2018
Background The etiology of more than half of all patients with X-linked intellectual disability remains elusive, despite array-based comparative genomic hybridization, whole exome or genome sequencing.
