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,...
Ecoregions are regions of relative homogeneity with respect to specific
ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing
awareness that effective management of environmental resources must be undertaken
with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial
framework for assessing, managing, and monitoring ecosystems that...
The visualization of climate patterns is a major theme in cartography. Short-term
dramatic weather events such as hurricanes and tornado outbreaks are mapped and
displayed immediately in order to capitalize on the sensational nature of the events, and
to quickly and accurately convey the information to emergency workers and the...
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...
Stream temperature response of first and second order streams to the Blue River Landscape
Study (BRLS), an alternative land management strategy based on historic fire regimes, was
analyzed in the central Oregon Cascades. The BRLS treatment prescription of a 50% canopy
reduction and low intensity burn was applied with a...
The application of the collinearity solution by resection of the interior and exterior
orientation parameters of historical photographs is investigated. The spatial coordinates of seven
or more identifiable control points in the field of view of an historical photograph, combined
with image coordinates of the control point images, allow solution...
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...
This study traces the development history of the city of Corvallis, Oregon. Historic
reconstruction methods and GIS analysis are used to define and describe spatial aspects of the
city's expansion through time.
Pre-settlement and early settlement landscape conditions are considered. The city's
history is divided into three time periods, 1845-1900,...
Many studies have looked at human settlements around individual volcanoes for
volcanic risk analyses, but few have done a comparative study to identify possible global
patterns. With the use of Landsat ETM+ data, this study identifies and compares urban
proximity to the Decade Volcanoes to identify volcanic settlement patterns. These...
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...
