An Analysis Of Topographic Effects On Landsat Thematic Mapper Image Using Digital Terain Data, Xiaomin Liu

Masters Theses

A comprehensive literature review on the simulation and corrections of topographic variations in remote sensing data was presented. The effects of topography on the scene radiance of LANDSAT thematic mapper (TM) image were examined in the context of the remote sensing of vegetation m Great Smoky Mountains National Park (GSMNP).

To simulate the image intensity component due to varying orientation of surface elements, two reflectance models were adopted to generate the synthetic images from a Digital Elevation Model (DEM). Visual and analytical procedures were developed to register the TM image to the DEM data.

The dark tones of scene radiance …

Prediction Of Forest Type And Productivity Index On Disturbed Sites In Great Smoky Mountains National Park, Charlotte Pyle

Masters Theses

A study was conducted in a portion of the permanent vegetation plots established by Uplands Field Research Laboratory in Great Smoky Mountains. The plots were located in the northwestern portion of the park in the vicinity of Cades Cove and Tremont on sites previously disturbed by chestnut blight, logging, fire, farming activities, and livestock grazing. Estimated plot productivity, and data on vegetation, soils, and topographic parameters were available from previous study of these plots. The purpose of the present study was to develop methods to predict forest cover type and plot productivity index score using site and disturbance history-related factors. …
