A five-year analysis of MODIS NDVI and NDWI for grassland drought assessment over the central Great Plains of the United States A five-year analysis of MODIS NDVI and NDWI for grassland drought assessment over the central Great Plains of the United States
A five-year (2001–2005) history of moderate resolution imaging spectroradiometer (MODIS) normalized difference vegetation index (NDVI) and normalized difference water index (NDWI) data was analyzed for grassland drought assessment within the central United States, specifically for the Flint Hills of Kansas and Oklahoma. Initial results show strong relationships among NDVI, NDWI, and...

Mapping an invasive plant, Phragmites australis, in coastal wetlands using the EO-1 Hyperion hyperspectral sensor Mapping an invasive plant, Phragmites australis, in coastal wetlands using the EO-1 Hyperion hyperspectral sensor
Mapping tools are needed to document the location and extent of Phragmites australis, a tall grass that invades coastal marshes throughout North America, displacing native plant species and degrading wetland habitat. Mapping Phragmites is particularly challenging in the freshwater Great Lakes coastal wetlands due to dynamic lake levels and vegetation diversity. We tested the...

Deriving a light use efficiency model from eddy covariance flux data for predicting daily gross primary production across biomes Deriving a light use efficiency model from eddy covariance flux data for predicting daily gross primary production across biomes
The quantitative simulation of gross primary production (GPP) at various spatial and temporal scales has been a major challenge in quantifying the global carbon cycle. We developed a light use efficiency (LUE) daily GPP model from eddy covariance (EC) measurements. The model, called EC-LUE, is driven by only four variables: normalized difference vegetation index (NDVI)...

Canadian and U.S. Cooperation for the development of standards and specifications for emerging mapping technologies Canadian and U.S. Cooperation for the development of standards and specifications for emerging mapping technologies
The mapping community is witnessing significant advances in available sensors, such as medium format digital cameras (MFDC) and Light Detection and Ranging (LiDAR) systems. In this regard, the Digital Photogrammetry Research Group (DPRG) of the Department of Geomatics Engineering at the University of Calgary has been actively involved in the development of standards and specifications...

Facing tomorrow’s challenges—U.S. Geological Survey science in the decade 2007–2017 Facing tomorrow’s challenges—U.S. Geological Survey science in the decade 2007–2017
Executive Summary In order for the U.S. Geological Survey (USGS) to respond to evolving national and global priorities, it must periodically reflect on, and optimize, its strategic directions. This report is the first comprehensive science strategy since the early 1990s to examine critically major USGS science goals and priorities. The development of this science strategy comes at a time...

SAR measurements of surface displacements at Augustine Volcano, Alaska from 1992 to 2005 SAR measurements of surface displacements at Augustine Volcano, Alaska from 1992 to 2005
Augustine volcano is an active stratovolcano located at the southwest of Anchorage, Alaska. Augustine volcano had experienced seven significantly explosive eruptions in 1812, 1883, 1908, 1935, 1963, 1976, and 1986, and a minor eruption in January 2006. We measured the surface displacements of the volcano by radar interferometry and GPS before and after the eruption in 2006. ERS-1/2...

Evaluating detection probabilities for American marten in the Black Hills, South Dakota Evaluating detection probabilities for American marten in the Black Hills, South Dakota
Assessing the effectiveness of monitoring techniques designed to determine presence of forest carnivores, such as American marten (Martes americana), is crucial for validation of survey results. Although comparisons between techniques have been made, little attention has been paid to the issue of detection probabilities (p). Thus, the underlying assumption has been that detection...

Determinants of elephant distribution at Nazinga Game Ranch, Burkina Faso Determinants of elephant distribution at Nazinga Game Ranch, Burkina Faso
We used seasonal ground total counts and remote sensing and GIS technology to relate elephant (Loxodonta africana africana) distribution at Nazinga Game Ranch to environmental and anthropogenic factors. Variables used in analyses were normalized difference vegetation index, elevation, stream density, density of poaching and human illegal activities, distance to dams, distance to rivers...

A project for monitoring trends in burn severity A project for monitoring trends in burn severity
Jeff Eidenshink, Brian Schwind, Ken Brewer, Zhi-Liang Zhu, Brad Quayle, and Elected officials and leaders of environmental agencies need information about the effects of large wildfires in order to set policy and make management decisions. Recently, the Wildland Fire Leadership Council (WFLC), which implements and coordinates the National Fire Plan (NFP) and Federal Wildland Fire...

Online catalog of world-wide test sites for the post-launch characterization and calibration of optical sensors Online catalog of world-wide test sites for the post-launch characterization and calibration of optical sensors
In an era when the number of Earth-observing satellites is rapidly growing and measurements from these sensors are used to answer increasingly urgent global issues, it is imperative that scientists and decision-makers rely on the accuracy of Earth-observing data products. The characterization and calibration of these sensors are vital to achieve an integrated Global Earth Observation...

Genetic algorithm based adaptive neural network ensemble and its application in predicting carbon flux Genetic algorithm based adaptive neural network ensemble and its application in predicting carbon flux
To improve the accuracy in prediction, Genetic Algorithm based Adaptive Neural Network Ensemble (GA-ANNE) is presented. Intersections are allowed between different training sets based on the fuzzy clustering analysis, which ensures the diversity as well as the accuracy of individual Neural Networks (NNs). Moreover, to improve the accuracy of the adaptive weights of individual NNs, GA is...
