A Multitemporal Analysis Of Georgia's Coastal Vegetation, 1990-2005, Charles, Iii F. Breeden
A Multitemporal Analysis Of Georgia's Coastal Vegetation, 1990-2005, Charles, Iii F. Breeden
Geosciences Theses
Land and vegetation changes are part of the continuous and dynamic cycle of earth system variation. This research examines vegetation changes in the 21-county eco-region along coastal Georgia. The Advanced Very High Resolution Radiometer (AVHRR) with Normalized Difference Vegetation Index (NDVI) data is used in tandem with a Principal Component Analysis (PCA) and climatic variables to determine where, and to what extent vegetation and land cover change is occurring. This research is designed around a 16 year time-series from 1990-2005. Findings were that mean NDVI values were either steady or slightly improved, and that PC1 (Healthiness) and PC2 (Time-Change) explained …

Remote Sensing And Gis Analysis Of Spatial Distribution Of Fracture Patterns In The Makran Accretionary Prism, Southeast Iran, Shankar Babu Pokharel
Geosciences Theses
This study shows that remote sensing and GIS are powerful tools in identifying geologically induced lineaments from digitally enhanced ETM+ satellite imageries and the digital elevation model (DEM) in remote areas such as the Makran accretionary prism, southeast Iran. The presence of the conjugate shear fractures in the eastern part, along with the extensional, and the presence of reidal sets associated with the subsidiary fractures of the Minab-Zendal fault system in the western part, suggests that the structural pattern changes from pure shear to simple shear from east to the west across the prism. Moreover, the gradual increase in the …
