Quantification of the topographic slope from radar satellite imagery

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
A specificity of Synthetic Aperture Radar (SAR) scenes is to display geometric distortions depending on both the system of acquisition ant its relation with the topography. Establishing the geometric relationship between the radar sensor parameters and the related surface deformation should therefore provide quantitative information on the topographic ...

COUPLING BETWEEN STRATIGRAPHIC AND TOPOGRAPHIC EFFECTS ON SLOPES

Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015
In this paper the seismic response of simple slope geometries under vertically propagating in-plane shear waves is assessed through two-dimensional finite element analyses to investigate the amplification of the ground motion induced by soil topography.

Topographic measurements of slope streaks on Mars

Icarus, 2016
Abstract Slope streaks are enigmatic, actively forming albedo features occurring on slopes in high-albedo, low-thermal-inertia, dust-rich equatorial regions on Mars. They are a specifically martian phenomenon with no direct analogs on the Earth. Their morphology suggests that the streaks are initiated at their upslope tips and propagate down to their

Topographic Waves over the Continental Slope

Journal of Physical Oceanography, 1988
Abstract Current meter data taken during a one-year period over the continental slope and upper rise in three cross-isobath sections have been examined for energy distribution, coherence, and phase propagation of topographic waves. A peak at 15 days is present in the energy preserving spectrum of the near-bottom currents on the rise and slope.

Topographic slope as an estimator of acoustic impedance

Sedimentary Geology, 1997
Abstract Seismic models of large outcrops have provided important insights into the nature of seismic unconformities and other elements of sequence stratigraphy. Further advances in outcrop modelling critically depend on more detailed acoustic impedance functions as a basis for the seismic models.

Influence of resolution on slope in areas with different topographic characteristics

Computers & Geosciences, 2012
This article studied slope scaling effects in six study areas in China. The areas had different terrain characteristics and were examples of distinct regions that are regarded in China as a distinct form of modeling and assessment of erosion and hydrology. The resolutions used in this paper including 10, 25, 50 and 100m.
