Producing a Canopy Height Map Over a Large Region Using Heterogeneous LIDAR Datasets
(2014)Accurate and unbiased wall-to-wall canopy height maps for large regions are useful to forest scientists and managers for several reasons such as carbon accounting and wildfire fuel-load monitoring. Airborne lidar is ... -
Accuracy Assessment of the NLCD 2006 Impervious Surface for Roanoke and Blacksburg
(2014)Impervious surface map products are important for the study of urbanization, urban heat island effects, watershed hydrology, water pollution, and ecosystem services in general. At the conterminous US scale, impervious ... -
Mapping Stable Nitrogen Isotopes Using Hyperspectral Imagery
(2014)As nitrogen deposition increases globally, ecosystem changes will occur. It is important to understand the growth response of different ecosystems and where nitrogen retention will occur. Stable isotopes of foliar nitrogen ... -
Crowds for Clouds: Using an Internet Workforce to Interpret Satellite Images
(2014)A chronologically ordered sequence of satellite images can be used to learn how natural features of the landscape change over time. For example, we can learn how forests react to human interventions or climate change. ... -
Investigating Forest Conversion Across Several Scales of Urbanization in the Eastern United States
(2014)Urbanization in the United States has clearly impacted land cover, and land use and land cover change (LULCC) patterns. A great body of literature has addressed the negative results of increased sprawl and a supporting ... -
Analysis of Crop Phenology Using Time-Series MODIS Data and Climate Data
(2014)Understanding crop phenology is fundamental to agricultural production, management, planning and decision-making. In the continental United States, key phenological stages are strongly influenced by meteorological and ... -
A model using marginal efficiency of investment to analyze carbon and nitrogen interactions in terrestrial ecosystems
(European Geosciences Union, 2014-09-12)Carbon (C) and nitrogen (N) cycles are coupled in terrestrial ecosystems through multiple processes including photosynthesis, tissue allocation, respiration, N fixation, N uptake, and decomposition of litter and soil organic ... -
On-the-Fly Massively Multitemporal Change Detection Using Statistical Quality Control Charts and Landsat Data
(Institute of Electrical and Electronics Engineers (IEEE), 2014-06)One challenge to implementing spectral change detection algorithms using multitemporal Landsat data is that key dates and periods are often missing from the record due to weather disturbances and lapses in continuous ... -
Landscape Dynamics on the Island of La Gonave, Haiti, 1990-2010
(MDPI, 2013-09-16)The island of La Gonave lies northwest of Port-au-Prince and is representative of the subsistence Haitian lifestyle. Little is known about the land cover changes and conversion rates on La Gonave. Using Landsat images from ...
