Kinematic And Tectonic Significance Of The Fold- And Fault- Related Fracture Systems In The Zagros Mountains, Southern Iran, Katayoun Mobasher
Kinematic And Tectonic Significance Of The Fold- And Fault- Related Fracture Systems In The Zagros Mountains, Southern Iran, Katayoun Mobasher
Geosciences Dissertations
Enhancement methods applied on various satellite images (ASTER, ETM and RADAR SAT-1) facilitated the identification and mapping of tectonic fractures in the Zagros fold-and-thrust belt in southwest Iran. The results of the fracture analysis on these enhanced images reveal four principal fracture sets within each fold structure: (i) an axial set defined by normal faults oriented parallel to the fold axial trace, (ii) a cross-axial, extensional fracture set oriented perpendicular to the fold axial trace, (iii) and two sets of intersecting shear fractures, oriented at an acute angle to the cross-axial set. Study of the enhanced images also revealed five …
Improved Hyperspectral Image Testing Using Synthetic Imagery And Factorial Designed Experiments, Joseph P. Bellucci
Improved Hyperspectral Image Testing Using Synthetic Imagery And Factorial Designed Experiments, Joseph P. Bellucci
Theses and Dissertations
The goal of any remote sensing system is to gather data about the geography it is imaging. In order to gain knowledge of the earth's landscape, post-processing algorithms are developed to extract information from the collected data. The algorithms can be intended to classify the various ground covers in a scene, identify specific targets of interest, or detect anomalies in an image. After the design of an algorithm comes the difficult task of testing and evaluating its performance. Traditionally, algorithms are tested using sets of extensively ground truthed test images. However, the lack of well characterized test data sets and …
Satellite Image Processing For Biodiversity Conservation And Environmental Modeling In Kyrgyz Republic National Park, Galina N. Fet
Satellite Image Processing For Biodiversity Conservation And Environmental Modeling In Kyrgyz Republic National Park, Galina N. Fet
Theses, Dissertations and Capstones
There is a need for extensive surveys of living organisms at a global scale; digital data exchange and storage is an essential part of such studies. Biodiversity inventory of fungi, which play an essential role in the health of the mountainous conifer forests of a developing country – Kyrgyz Republic, was linked to the vegetation classification produced from the high-resolution satellite imagery. Terra ASTER and SRTM90 imagery was used as a base map for the ecosystem modeling of the species and habitat distribution and for the three-dimensional representation, especially valuable for the mountainous landscapes of the Ala Archa National Park. …
Sediment Transport On A River-Dominated Shallow Water Shelf: Atchafalaya Bay Region, Louisiana, Renee T. Bellotte
Sediment Transport On A River-Dominated Shallow Water Shelf: Atchafalaya Bay Region, Louisiana, Renee T. Bellotte
LSU Master's Theses
Cold front passage impacts on sediment transport on the inner continental shelf near Atchafalaya Bay were studied, combining satellite imagery and in-situ meteorological and oceanographic measurements. An empirical model relating atmospherically corrected MODIS imagery reflectance to surface measurements of suspended sediment concentration was developed and successfully applied to the coastal waters. An equation for predicting total suspended sediment from Nephelometric Turbidity Units was also applied to the water column at 1, 2, and 3 meters from the seabed. Five case study weeks were selected to examine the dynamics of pre-frontal and post-front forcing mechanisms on sediment transport in a fine-grained …
Assessment And Analysis Of Quikscat And Coamps Model Vector Wind Products For The Gulf Of Mexico: A Long-Term And Hurricane Perspective, Neha Sharma
LSU Master's Theses
Global weather changes have become a matter of grave concern in hurricane prone areas as intensities of hurricanes are observed to be increasing every year, necessitating improved monitoring capabilities. NASA’s QuikSCAT satellite sensor has provided significant support in analyzing and forecasting winds for the past 8 years. In this study, the performance of QuikSCAT products, including JPL’s latest L2B 12.5km swath winds, was evaluated against buoy-measured winds in the Gulf of Mexico. The long-term study period was 1/2005 – 2/2007. The Coupled Ocean/Atmospheric Mesoscale Prediction System (COAMPS) was also assessed. The regression analyses showed very good results for QuikSCAT products, …
