Evaluating Unmanned Aerial Vehicle Remote Sensing Towards Improving Site-specific Management
(2019-10-15)Unmanned aerial vehicles (UAVs) offer exciting new potentials within the field of precision agriculture. However, the technology remains in an experimental setting because of questions concerning data quality and quantity. ... -
Factors Structuring Treeline Dynamics of the Nepal Himalaya
(2017-05-22)The alpine treeline ecotone is an important component of mountain ecosystems of the Nepal Himalayas; it plays a vital role in the livelihood of indigenous people and provides ecosystem services. However, the region faces ... -
Fractional Snow-Cover Mapping Through Artificial Neural Network Analysis of MODIS Surface Reflectance.
(2010-07-14)Accurate areal measurements of snow-cover extent are important for hydrological and climate modeling. The traditional method of mapping snow cover is binary where a pixel is approximated to either snow-covered or snow-free. ... -
Greening of Recently Deglaciated Lands on the Kenai Peninsula
(2018-05-01)Poleward vegetation expansion has affected Alaska for decades and due to recently increased rates of warming, the expansion will accelerate. Glacier recession in the region has exposed land that was previously ice covered. ... -
Ground Truthing Sargassum in Satellite Imagery: Assessment of Its Effectiveness as an Early Warning System
(2012-02-14)Large aggregations of Sargassum, when at sea, provide important habitat for numerous marine species of vertebrates and invertebrates. It is especially important for the young of several species of sea turtles. However, ... -
Human Appropriation of Net Primary Productivity (HANPP) in Texas: A Statewide Analysis of Sustainability in the Agricultural and Timber Sectors
(2010-07-14)The sustainability of the Texas agricultural and timber sectors is measured using the ratio of human appropriation of net primary productivity (HANPP) to available net primary productivity (NPP) on a county-by-county basis ... -
Implementation of Genomic and Phenomic Tools for Introgression of Reinstated Sorghum Conversion (RSC) Germplasm
(2019-07-24)Genotypic variance is necessary for trait improvement as limited diversity can reduce genetic gain in crop improvement. To maintain genetic diversity, a wealth of germplasm exists in the USDA-ARS sorghum [Sorghum bicolor ... -
Implementing Unmanned Aerial Systems Within a Field-Based Maize (Zea mays L.) Breeding Program: Improving Yield Prediction and Understanding Temporal QTL Expression of Plant Height
(2019-07-18)Unmanned aerial system (UAS) technologies are becoming common place within field-based agriculture programs allowing breeders to evaluate greater numbers of genotypes, reducing resource inputs and maintaining unbiased data ... -
Infrastructure Enabled Autonomy Acting as an Intelligent Transportation System for Autonomous Cars
(2018-05-01)Autonomous cars have the ability to increase safety, efficiency, and speed of travel. Yet many see a point at which stand-alone autonomous agents populate an area too densely, creating increased risk - particularly when ... -
Investigating impacts of natural and human-induced environmental changes on hydrological processes and flood hazards using a GIS-based hydrological/hydraulic model and remote sensing data
(2009-06-02)Natural and human-induced environmental changes have been altering the earth's surface and hydrological processes, and thus directly contribute to the severity of flood hazards. To understand these changes and their impacts, ... -
Investigation of coastal dynamics of the Antarctic Ice Sheet using sequential Radarsat SAR images
(2009-05-15)Increasing human activities have brought about a global warming trend, and cause global sea level rise. Investigations of variations in coastal margins of Antarctica and in the glacial dynamics of the Antarctic Ice Sheet ... -
Investigation of Glacial Dynamics in the Lambert Glacier-Amery Ice Shelf System (LAS) Using Remote Sensing
(2012-12-10)Numerous recent studies have documented dynamic changes in the behaviors of large marine-terminating outlet glaciers and ice streams in Greenland, the Antarctic Peninsula, and West Antarctica. However, fewer observations ... -
Modeling Endemic Bark Beetle Populations in Southwestern Ponderosa Pine Forests
(2015-02-20)Bark beetle populations phase between epidemic, outbreak levels, and low population density, endemic levels. The majority of scientific research is focused on outbreak populations because of the associated economic, ... -
Multi-scale texture analysis of remote sensing images using gabor filter banks and wavelet transforms
(2009-05-15)Traditional remote sensing image classification has primarily relied on image spectral information and texture information was ignored or not fully utilized. Existing remote sensing software packages have very limited ... -
Observing Short-Term Geomorphic Change in a Human-Modified River Using Terrestrial Repeat Photographs and Traditional Surveys: Uncompahgre River, Colorado, USA
