Chameleon is a physics-based landscape modeling software system designed for modeling and simulations applications. Hyperspectral laboratory, field, and imaging spectrometer measurements are collected as empirical foundation data. Linear spectral unmixing is performed to decompose each image pixel into spectral endmembers. Mathematical manipulation of these fractional abundances and introduction of new...
An emergency management system integrating remote sensing and geographic
information systems applied to emergency preparation, response, and recovery could
have reduced casualties and damage after the August 17, 1999 Kocaeli, Turkey
earthquake. Model system components include a horizontally and vertically distributed
knowledge base, LIDAR 3D urban modeling, automatic feature extraction,...
The purpose of this paper was to examine if the depth and degree of circularity of weathering pits affects the accumulation of sediment. Thirty pits were surveyed over two one-week periods on Dance Hall Rock. Weathering pits were measured to determine their maximum width, minimum width, vertical depth, and depth...
Spectral profiles, transformed divergence values, and feature space derived from Landsat Thematic Mapper (TM) data were used to analyze the ability of four false color composites to discriminate between different classes of salt-affected soils. To compare the spatial distribution of salt-affected soil classes, maps were generated for each false color...
Tsunamis pose a major threat to Oregon's coastal communities. Evacuation is
the best method to mitigate for tsunamis. Planning for tsunami evacuation is underway
in Oregon's coastal communities. Current methodologies use tsunami inundation
models and population for evacuation planning. Tsunamis from a Cascadia subduction
zone (CSZ) earthquake will create more...
In this study, LIDAR, light detection and ranging, was examined as to its ability to
depict the existence of forest roads and 'legacy' roads. LIDAR is most often used to
'see' though the trees or vegetation to get an accurate representation of the terrain. As
opposed to trying to remove...
The Geographic Information System (GIS) is an invaluable tool in manipulating and
interpreting world scale datasets. In recent years it has become the standard link between
water resource study and the ever-increasing numbers of high quality data sets. This
paper describes the use of Geographic Information Systems for gathering and...
The main purpose of this project is to describe the hydrologic characteristics, with and without
regulation by dams, of the Coast and Middle Forks of the Willamette River, including the
floodplain, from the confluence to approximately eight miles upstream. The research is intended
to assess the future potential of the...
Field data collection techniques in combination with remote
sensing techniques were used to interpret and map the complex flow pattern of
the numerous glaciers comprising the Juneau lcefield, spanning the Alaska-
Canada boundary range. The extensive nature of the icefield mandated the use
of a variety of methods for surveying...
Louisiana Army Ammunition Plant (LAAP), located near Shreveport, Louisiana, is a
government-owned contractor-operated plant. Its purpose is to manufacture, load and
assemble ammunition items. Area P has been used over the past 40 years to dump
explosive-laden wastewater into 16 unlined lagoons. In 1989 LAAP was placed on the
National...
