Comparison and validation of recent freely-available ASTER-GDEM ver1, SRTM ver4.1 and GEODATA DEM-9S ver3 digital elevation models over Australia

TL;DR: In this paper, the authors investigated the quality of three publicly available elevation model datasets over Australia: (i) the 9 arc second national GEODATA DEM-9S ver3 from Geoscience Australia and the Australian National University, (ii) the 3 arc second SRTM ver4.1 from CGIAR-CSI, and (iii) the 1 arc second ASTER-GDEM ver1 from NASA/METI.
Journal ArticleDOI

New ultrahigh‐resolution picture of Earth's gravity field

TL;DR: In this article, the authors provided an unprecedented ultra-high resolution picture of Earth's gravity over all continents and numerous islands within ± 60 degree latitude, achieved through augmentation of satellite and terrestrial gravity with topography data, and use of massive parallel computation techniques.
Journal ArticleDOI

Growth of Epithelial Organoids in a Defined Hydrogel.

TL;DR: Since the fibrin/laminin matrix supports long‐term expansion of all tested murine and human epithelial organoids, this hydrogel can be widely used as a defined equivalent to BME.

Comparison of free high-resolution digital elevation data sets (ASTER GDEM2,

TL;DR: In this paper, the authors compared and evaluated the latest version of the Advanced Spaceborne Thermal Emission (ASME) for global digital elevation models (DEMs) available on the web.
Journal ArticleDOI

Comparison of free high resolution digital elevation data sets (ASTER GDEM2, SRTM v2.1/v4.1) and validation against accurate heights from the Australian National Gravity Database

TL;DR: In this article, the authors compare and evaluate the latest release of the Advanced Spaceborne Thermal Emission Reflectometer DEM (ASTER GDEM2) and two DEMs based on the Shuttle Radar Topography Mission (SRTM) as released by the United States Geological Survey (SR TM3 USGS version 2.1) and by the Consortium for Spatial Information (SRTM CGIAR-CSI version 4.1).
