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 ...

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.

A Fully Automatic Algorithm for Editing the TanDEM-X Global DEM

Remote Sensing, 2020
The spaceborne mission TanDEM-X successfully acquired and processed a global Digital Elevation Model (DEM) from interferometric bistatic SAR data at X band. The product has been delivered in 2016 and is characterized by an unprecedented vertical accuracy.

TanDEM-X Long-Term System Performance After 10 Years of Operation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The TanDEM-X mission, formed by the TanDEM-X satellite in cooperation with its almost identical twin TerraSAR-X (TSX), has mainly been designed to acquire bistatic synthetic aperture radar (SAR) images of the Earth. Initiated in 2010, the primary mission

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 ...

Cascaded multi-baseline interferometry with bistatic TerraSAR-X/TanDEM-X observations for DEM generation

, 2021
As the spaceborne mission dedicated to bistatic SAR interferometry (InSAR), the TerraSAR-X/TanDEM-X satellite constellation can acquire highly coherent data pairs with flexible baseline configurations and minimal atmospheric disturbances, which are well ...

Improving Forest Height-To-Biomass Allometry With Structure Information: A Tandem-X Study

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Allometric relations that link forest above ground biomass to top forest (i.e., canopy) height are of particular significance in the context of lidar and interferometric synthetic aperture radar remote sensing, as both techniques allow accurate height ...

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.
