the high hillsides of the tehran metropolis are prone to landslides due to the climatic conditions and the geological, geomorphologicalcharacteristics of the region. therefore, it is vitally important that a landslide susceptibility map of the region be prepared. for thispurpose, thematic layers including landslide inventory, lithology, slope, aspect, curvature, distance to stream, distance to ...

introduction in recent decades, a large variety of science experts, including geology and mine scientists, have considered remote sensing technology as one of the most important instruments to receive information. access to hyper spectral data is one of the main evolutions in the remote sensing technology. the main feature of the technology is its application in identification of minerals and d...

expensive to provide these maps  with field measurements  therefore  it is better to use new methods. this study provides a lithological and alteration mapping units with dominant minerals based on hyperspectral images of eo1-hyperion satellite. to do so, two different zones  were  investigated:  the  cuprite-nevada  and  mozahem  volcano  in  iran  which  have suitable conditions for our study...

This paper presents a model for quantitative risk analysis with the application of geographic information systems (GISs) using Bayesian theory. It was used for the thematic integration of maps in a natural state (vegetation, geological-geotechnical, natural drainage and gradient). A landslide susceptibility map was produced based on this integration associated with vulnerability data (time and ...

This open access book presents new theory and methods on compiling lithofacies paleogeographic maps as key tool for guiding geological survey shale gas

We explored the potential incorporation of Sentinel-2A imagery for rock unit determination in Croatian karst region dominated by carbonate rocks. The various lithological units are sources both stone aggregates and dimension stone, their spatial distribution is high importance mineral resource management. presented approach included preprocessing processing existing analog data (geological maps...

People gesture during spatial tasks (Alibali et al., 2001; Kita & Özyürek, 2003; Morsella & Krauss, 2004), and how they gesture reveals information about ongoing cognitive processes (Alibali & Kita, 2008; Church & Goldin-Meadow, 1986; Schwartz & Black, 1996). One task that requires many spatial processes is reading geologic maps. Geologic maps give information about the spatial relationships of...

[1] We show that the spatial coherency of the ambient seismic field can be used for attenuation tomography in the western United States. We evaluate the real portion of the spatial coherency with an elastic geometric spreading term (a Bessel function) and a distance dependent decay (an attenuation coefficient). In order to invert the spatial coherency, a weight stack inversion technique is appl...
