DLR’s X-band interferometric SAR system onboard the Shuttle Radar Topography Mission (SRTM) has been flown successfully in February 2000 and acquired 3660 G bytes of raw data to be processed to a near global Digital Elevation Model (DEM) of the earth with an absolute height accuracy of ±16m. Before starting the operational processing deferent kinds of calibration and motion compensation activit...

Terraforming of a planetary body (planet or moon) or planetary ecosynthesis is the hypothetical process of deliberately modifying its atmosphere composition, temperature, topography, or ecology to be similar to those of Earth to make it habitable for Terran organism, including humans. Terraforming is a common concept in science fiction. In fact, Jack Williamson, a science fiction writer, coined...

Functional biogeography may bridge a gap between field-based biodiversity information and satellite-based Earth system studies, thereby supporting conservation plans to protect more species and their contributions to ecosystem functioning. We used airborne laser-guided imaging spectroscopy with environmental modeling to derive large-scale, multivariate forest canopy functional trait maps of the...

New and forthcoming Earth Observation satellite missions include in their payloads remote sensing instruments of very low spatial resolution. Data and product validation from these sensors introduces a set of specific scientific issues that make it necessary to carry out specific measurements over large extended areas. The main objective of the VALENCIA Anchor Station is to define a reference a...

Report keratoconus in two patients with a long history of wrestling without any risk factor for corneal ectasia and reviewing the possible pathogenesis. To confirm suspicion of keratoconus, corneal topography was performed using scanning slit topography system and Orbscan. In two wrestlers with the complaint of visual loss in their eyes and IOP raising, corneal topography was performed and de...

Cascade processes generically lead to multifractal fields and have been used for simulating turbulent systems including clouds, rain, temperature, passive scalars and the wind as well as for solid earth fields such as rock density, magnetization and topography. In spite of their importance, most applications use primitive discrete scale ratio processes which singularize scales which are integer...

The South American Altiplano in the Andes is, aside from Tibet, the most extensive high plateau on Earth. This semiarid area represents important water resources storages, including the Lakes Titicaca and Poopó located in the northern and central Altiplano, respectively. The two lake basins and the southern saltpans constitute a large watershed, called the Lake Titicaca, Desaguadero River, Lake...

Nowadays, multidimensional Synthetic Aperture Radar (SAR) imagery has raised as a powerful tool to extract physical information about the Earth surface. One of the main parameters which characterizes these multidimensional data is the complex correlation coefficient between two SAR images. It has been demonstrated, in the related literature, that this parameter can be sensible to different phys...

Meshes made from 3D points are used to represent many important geoscience concepts such as the surface of the Earth (topography), rock strata (horizons) and faults. When creating complex computer models, a geoscientist may need to directly affect the shape of such a surface to bring in in line with other data. We present a method that allows a geoscientist to precisely interact with these surf...
