Evaluation and Application of a New Shape-sensitive Metric Useful for Characterizing Both Spectral Curves and Lidar Waveforms
<p>This dissertation seeks to investigate hyperspectral and waveform LiDAR datasets through a new analytical framework called Moment Distance method that uses a metric derived from the shape of the curve (spectral or waveform). In the case of hyperspectral data, the shape of the reflectance curve …

Examining Land Use/Land Cover Change and Potential Causal Factors in the Context of Climate Change in Sagarmatha National Park, Nepal
<p>In the context of growing tourism and global warming, the fragile landscape of the Himalayas is under immense pressure because of rapid land cover changes in developing countries like Nepal. Remotely sensed data combined with ethnographic knowledge are useful tools for studying such changes. The …

Spatial Analysis of Soil Creep Rates on Mount Sequoyah, Fayetteville Arkansas
<p>Mount Sequoyah in Fayetteville, Arkansas, is a part of the Boston Mountains, which are considered a deeply dissected plateau. The area is prone to mass wasting, which is the general downslope movement of sediments, soils, and rock through different processes that cause instabilities along a …

Defining the Regional and Seasonal Climatic Response of Long Douglas-Fir Tree-Ring Chronologies in Central Mexico
<p>Problems with instrumental climate data and difficulties arising from the distribution of sensitive, long-term tree-ring chronologies across Mexico's complex terrain have made it difficult to model the climate signal of tree-rings in Mexico. The objective of this research is to utilize the …
