Modeling the human invader in the United States
Thomas J. Stohlgren, Catherine S. Jarnevich, Chandra P. Giri
2010, Journal of Applied Remote Sensing (4)
Modern biogeographers recognize that humans are seen as constituents of ecosystems, drivers of significant change, and perhaps, the most invasive species on earth. We found it instructive to model humans as invasive organisms with the same environmental factors. We present a preliminary model of the spread of modern humans in...

Use of land surface remotely sensed satellite and airborne data for environmental exposure assessment in cancer research
S.K. Maxwell, J.R. Meliker, P. Goovaerts
2010, Journal of Exposure Science and Environmental Epidemiology (20) 176-185
In recent years, geographic information systems (GIS) have increasingly been used for reconstructing individual-level exposures to environmental contaminants in epidemiological research. Remotely sensed data can be useful in creating space-time models of environmental measures. The primary advantage of using remotely sensed data is that it allows for study at the...

D.J. Selkowitz
2010, Remote Sensing of Environment (114) 1338-1352
Shrub cover appears to be increasing across many areas of the Arctic tundra biome, and increasing shrub cover in the Arctic has the potential to significantly impact global carbon budgets and the global climate system. For most of the Arctic, however, there is no existing baseline inventory of shrub canopy...

Amit Angal, Xiaoxiong Xiong, Tae-young Choi, Gyanesh Chander, Aisheng Wu
2010, Journal of Applied Remote Sensing (4)
Remote sensing imagery is effective for monitoring environmental and climatic changes because of the extent of the global coverage and long time scale of the observations. Radiometric calibration of remote sensing sensors is essential for quantitative & qualitative science and applications. Pseudo-invariant ground targets have been extensively used to monitor...

G. Chander, X.(J.) Xiong, T.(J.) Choi, A. Angal
2010, Remote Sensing of Environment (114) 925-939
The ability to detect and quantify changes in the Earth's environment depends on sensors that can provide calibrated, consistent measurements of the Earth's surface features through time. A critical step in this process is to put image data from different sensors onto a common radiometric scale. This work focuses on...
An automated approach for reconstructing recent forest disturbance history using dense Landsat time series stacks
Chengquan Huang, Samuel N. Goward, Jeffery G. Masek, Nancy Thomas, Zhiliang Zhu, James Vogelmann
2010, Remote Sensing of Environment (114) 183-198
A highly automated algorithm called vegetation change tracker (VCT) has been developed for reconstructing recent forest disturbance history using Landsat time series stacks (LTSS). This algorithm is based on the spectral–temporal properties of land cover and forest change processes, and requires little or no fine tuning for most forests with...

Automated masking of cloud and cloud shadow for forest change analysis using Landsat images
Chengquan Huang, Nancy Thomas, Samuel N. Goward, Jeffery G. Masek, Zhiliang Zhu, J.R.G. Townshend, James Vogelmann
2010, International Journal of Remote Sensing (31) 5449-5464
Accurate masking of cloud and cloud shadow is a prerequisite for reliable mapping of land surface attributes. Cloud contamination is particularly a problem for land cover change analysis, because unflagged clouds may be mapped as false changes, and the level of such false changes can be comparable to or many...

Gabriel B. Senay, P.H. Gowda, T.A. Howell, T.H. Marek
2009, Applied Engineering in Agriculture (25) 665-669
Numerous energy balance (EB) algorithms have been developed to make use of remote sensing data to estimate evapotranspiration (ET) regionally. However, most EB models are complex to use and efforts are being made to simplify procedures mainly through the scaling of reference ET. The Simplified Surface Energy Balance (SSEB) is...
