Three methods for estimating subpixel cover fractions in coarse resolution imagery

Creator:: Damon, Diane L.
Abstract:: Coarse resolution imagery, such as that produced by the MODIS instrument, poses the challenge of estimating sub-pixel proportions of di erent land cover types. This problem is di cult because of the variety and variability of vegetation within individual pixels. This thesis describes and compares two existing algorithms for estimating...

Vegetation characteristics expressed through transformed MODIS data : a MODIS tasseled cap

Creator:: Lobser, Sarah E.
Abstract:: The MODIS NBAR (M0D43B4) data space is explored in terms of biophysical variables with the objective of formulating a MODIS transformation relevant to global vegetation studies. The basic ideas of transform formulation were borrowed from the development of the TM Tasseled Cap transformation, but with differences in sampling strategy and...

Airborne videography as a classification and validation technique for Landsat TM-based vegetation mapping

Creator:: Barrett, Charley, 1965-
Abstract:: The Oregon Department of Fish and Wildlife's (ODFW) Ecological Analysis Center (EAC) is in the process of creating, from Landsat Thematic Mapper (TM) imagery, a vegetation map of Oregon that will meet the latest standards set by the National Gap Analysis Program. Since field verification is often expensive and by...

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...

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...

Mapping vegetation density and water inundation in a recovering wetland : the Mesopotamian Marshlands

Creator:: Bosley, Jon Michael
Abstract:: Once considered the largest wetland in Central Asia, the Mesopotamian Marshlands of Southeastern Iraq have nearly disappeared. Various hydrological projects by the Iraqi government and dam construction in the region have nearly destroyed these once rich freshwater wetlands by over 90%. With the launching of Operation Iraqi Freedom recent attempts...

Mapping vegetation using landsat TM and ETM+ in Eritrea

Creator:: Iyob, Biniam
Abstract:: The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...

A mathematical transformation of multi-angular remote sensing data for the study of vegetation change

Creator:: Friedel, Robert G.
Abstract:: Vegetation change is an important factor affecting the global carbon cycle, land-atmosphere interaction, and terrestrial ecology. The study of vegetation change on a global scale can be used to evaluate the impact of global climate change on terrestrial ecosystems. Satellite remote sensing can monitor vegetation change at the global scale,...

Development of 2D models to estimate nearshore bathymetry and sediment transport

Creator:: Splinter, Kristen D.
Abstract:: We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The ﬁrst two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

A comparison of modeling schemes for mapping daily evapotranspiration at high resolution using remote sensing

Creator:: Ring, Theresa
Abstract:: Evapotranspiration (ET) is an important component of the hydrologic cycle that transfers large quantities of water vapor away from Earth's surface into the atmosphere. In addition to having agricultural water management applications, including monitoring water rights compliance and irrigation scheduling, estimating ET is also important to quantify water used by...
