Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles
Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles
Masters Theses & Specialist Projects
Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …
Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan
Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan
Master's Theses
The objective of this project was to determine the degree and direction of association between the amount of mud/salt flat area and shorebird abundance during spring and early summer. This study used Landsat 5 to indirectly measure mudflat and salt flat areas at two wetland complexes within Kansas over a period of several years (1991-2008). These measurements were compared to shorebird surveys conducted by several individuals at both Quivira National Wildlife Refuge and Cheyenne Bottoms Wildlife Area. A correlation analysis showed that significant relationships exist between mud/salt flat area and the abundance of certain shorebird species. Correlation coefficients for individual …

Optimized Correlation Of Geophysical And Geotechnical Methods In Sinkhole Investigations: Emphasizing On Spatial Variations In West-Central Florida, Henok Gidey Kiflu
USF Tampa Graduate Theses and Dissertations
Abstract
Sinkholes and sinkhole-related features in West-Central Florida (WCF) are commonly identified using geotechnical investigations such as standard penetration test (SPT) borings and geophysical methods such as ground penetrating radar (GPR) and electrical resistivity tomography (ERT). Geophysical investigation results can be used to locate drilling and field testing sites while geotechnical investigation can be used to ground truth geophysical results. Both methods can yield complementary information. Geotechnical investigations give important information about the type of soil, groundwater level and presence of low-density soils or voids at the test location, while geophysical investigations like GPR surveys have better spatial coverage and …
