Multivariate thematic map visualization of the Oregon 2001 drought

Creator:: Theirl, David M.
Abstract:: 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...

An application of photogrammetric techniques to the measurement of historic photographs

Creator:: Strausz, David A. Jr
Abstract:: 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...

Volcanic vulnerability : Determining the relationship between urban proximity to volcanoes and human development

Creator:: Hogue, Jennifer A.
Abstract:: 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...

Using Data Loss and Duplication Maps to study data use associated with nearest-neighbor resampling

Creator:: Perigny, Mathew
Abstract:: Nearest-neighbor resampling is a common procedure used by cartographers to reproject raster data sets. This type of resampling is useful because it retains the data from the original raster data set. However, during nearest-neighbor resampling some of the original data will be lost as it is reprojected, while other data...

Deconstructing density : Assessing the per capita influence on vegetation and impervious surface area in Corvallis, Oregon

Creator:: Rempel, Marco Gascho
Abstract:: The density at which urban areas are developed has become a contentious issue, with advocates for compact cities in conflict with advocates for larger lots and suburban development. This research paper examines the associated impact of population density (grouped by residential zones) as measured by vegetation (Normalized Difference Vegetation Index)...

An evaluation of species-area curves created from a systematically sampled date set using an automated accumulation technique

Creator:: Dale, Becci
Abstract:: This paper examines the influence of species, method, and area on automated species-area curve created from a systematically sampled data set. Because this is a new approach to species-area curves, three tests were run to evaluate the performance of the data sets and accumulation technique. The tests involved 1) range...

Photorealistic landscape visualization : A step towards a Digital Earth

Creator:: Dey, Ryan M.
Abstract:: A Digital Earth is a visualization tool that uses the latest technologies to embed vast quantities of geographic data into easily understood information. By creating three-dimensional landscape visualizations that look as photorealistic as current technology allows, it becomes possible to see, explore, and spatially understand parts of the Earth as...

Extending the Ecosystem Management Decision Support system to enable data migration

Creator:: Crouse, Kenneth
Abstract:: In this work software is developed to take an ecosystem management tool used by the US Forest Service, the Ecosystem Management Decision Support (EMDS) system, and enhance its utility by capturing the results of an ecosystem assessment and saving them in a format that facilitates importation into other management tools,...

Vegetation analysis and spatial visualization of a tidal salt marsh

Creator:: Buchner, Ed L.
Abstract:: Mitchell Marsh, a tidal salt marsh in the Salmon River Estuary, was diked in the early 1960s. Restoration of the marsh, which began in late 1978, consisted of partial dike removal. Several studies have been conducted in the marsh, addressing the status of the developing salt marsh plant communities. Species...

4D data visualization incorporating time into 3D animations

Creator:: Boright, Jonathan
Abstract:: ArcView 3D Analyst is a powerful geospatial tool, and has proven very useful in 3D visualization and analysis. In most cases, 3D data models are temporally static, representing only one instance in time. For many applications, the 'missing' time dimension is of great significance, and there is a need to...

OSU 360 : developing a virtual tour mapping infrastructure for Oregon State University

Creator:: Waggoner, Scott
Abstract:: Details the development of the OSU 360 virtual tour system (www.oregonstate.edu/osu360) from May 2008 to May 2009. OSU 360 is a collaboration between the Department of Geosciences, University Housing and Dining Services, Central Web Services, Web Communications, and Admissions/Enrollment. This article details the project development from determining goals, distinguishing locations,...

Aspen age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem

Creator:: Larsen, Eric J.
Abstract:: Aerial photographs and field sampling were used to compare aspen (Populus tremuloides) age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem. The elk winter ranges studied were the northern range in Yellowstone National Park (YNP) and the Gallatin National Forest and the Sunlight/Crandall elk winter...

Multi-spatial scale representation of landscape transitions using landsat thematic mapper data and scale-space filters

Creator:: Lindeman, Dale R.
Abstract:: This thesis considered current approaches to describing landscape pattern, identified scale issues associated with defining objects, and explored techniques to reliably group elements based on land cover as represented by satellite imagery. It was recognized that there is an important need to develop tools that can be applied using remotely...

Mapping the thermal climate of the H. J. Andrews Experimental Forest, Oregon

Creator:: Smith, Jonathan W.
Abstract:: The H. J. Andrews Experimental Forest in the Cascades of central Oregon provides a unique opportunity to study spatial climate patterns on a relatively small scale. Historical records at the 64 square-kilometer site provide a spatiallydense 30-year dataset. Thermal regimes at the H. J. Andrews are generally known but the...

Land cover change along the Willamette River, Oregon

Creator:: Oetter, Doug Rudolph, 1962-
Abstract:: The Willamette River and its floodplain in northwest Oregon have changed dramatically since European settlement. At one time, the river was a vast complex system of braided channels with a broad floodplain forest; it has now been simplified by channelization and dams, and the forest has been removed to support...

A per-segment approach to improving aspen mapping from remote sensing imagery and its implications at different scales

Creator:: Heyman, Ofer
Abstract:: A per-segment classification system was developed to map aspen (Populus tremuloides) stands on Winter Ridge in central Oregon from remote sensing imagery. A 1-meter color infrared (CIR) image was segmented based on its hue and saturation values to generate aspen "candidates", which were then classified to show aspen coverage according...

The effects of land use changes on forest fires in major islands of Indonesia

Creator:: Lumban-Tobing, Pago L.
Abstract:: The study examines the effect of forest clearance on fire occurrences in major islands of Indonesia, namely: Borneo, Sumatra, Sulawesi and Irian Jaya. The working hypothesis of the study is that forest clearing is a necessary predecessor for extensive fires to occur. The study is designed to test the idea...

Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of Southern Oregon and Northern California : a Geographic Information System approach

Creator:: Zanger, Christopher
Abstract:: 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...
