In spite of the fact that the effect of earthquake on earth dams has been widely studied during the past decades, the complicated behavior of such earth structures against different seismological characteristics is still unknown. Such ambiguities necessitate more accurate studies using more comprehensive computation tools to achieve new results describing the behavior of such structures subject...

Spatiotemporal residual noise in terrestrial earth observation products, often caused by unfavorable atmospheric conditions, impedes their broad applications. Most users prefer to use gap-filled remote sensing products with time series reconstruction (TSR) algorithms. Applying currently available implementations of TSR large-volume datasets is time-consuming and challenging for non-professional...

DEFINITION: A geographic information system (GIS) is a computer application designed to perform a wide range of operations on geographic information. Geographic information is defined as information about locations on or near the surface of the Earth, and may be organized in a variety of ways. Thus a GIS includes functions to input, store, visualize, export, and analyze such information. Commer...

The 2012 Ahar-Varzegan earthquake and its aftershocks have not only caused huge damage with a severe loss of life and property but also induced many geo-hazards with the major type of collapse, creep, slip, debris flow, and fallings that are generally considered as landslide in this study which can cause continuous threats to the affected region. in this study, a semi-automated geo-hazard detec...

Photogrammetry is becoming a highly efficient alternative technique to laser-scanning for creating virtual outcrop models. It is easy to create a 3-dimensional digital model of an outcrop and extract geological information contained in it by using photos taken from different locations and integrating few free and/or cheap software. Subsequently, both the virtual outcrop and the geological data ...

We describe a software simulation test bed for evaluating Concepts of Operation (CONOPS) for Unmanned Aircraft Systems (UAS) flying earth science missions. The Mission Operational Concept Evaluation Framework (MOCEF) aids in the rapid evaluation of proposed system automation designs, including intelligent controllers for vehicles, sensor payloads, and decision support systems, on a wide range o...
