Modified Methodology for Projecting Coastal Louisiana Land Changes over the Next 50 Years
Steve B. Hartley
2009, Scientific Investigations Map 3098
The coastal Louisiana landscape is continually undergoing geomorphologic changes (in particular, land loss); however, after the 2005 hurricane season, the changes were intensified because of Hurricanes Katrina and Rita. The amount of land loss caused by the 2005 hurricane season was 42 percent (562 km2) of the total land loss...

Assessment of the short-term radiometric stability between Terra MODIS and Landsat 7 ETM+ sensors
Taeyoung Choi, Xiaoxiong Xiong, Gyanesh Chander, A. Angal
2009, Conference Paper, Geoscience and Remote Sensing Symposium, 2009 IEEE International, IGARSS 2009
Short-term radiometric stability was evaluated using continuous ETM+ scenes within a single orbit (contact period) and the corresponding MODIS scenes for the four matching solar reflective visible and near-infrared (VNIR) band pairs between the two sensors. The near-simultaneous earth observations were limited by the smaller swath size of ETM+ (183...

Multiscale sagebrush rangeland habitat modeling in southwest Wyoming
Collin G. Homer, Cameron L. Aldridge, Debra K. Meyer, Michael J. Coan, Zachary H. Bowen
2009, Open-File Report 2008-1027
Sagebrush-steppe ecosystems in North America have experienced dramatic elimination and degradation since European settlement. As a result, sagebrush-steppe dependent species have experienced drastic range contractions and population declines. Coordinated ecosystem-wide research, integrated with monitoring and management activities, would improve the ability to maintain existing sagebrush habitats. However, current data only...
Climate, lightning ignitions, and fire severity in Yosemite National Park, California, USA
J.A. Lutz, J. W. van Wagtendonk, A. E. Thode, J.D. Miller, J.F. Franklin
2009, International Journal of Wildland Fire (18) 765-774
Continental-scale studies of western North America have attributed recent increases in annual area burned and fire size to a warming climate, but these studies have focussed on large fires and have left the issues of fire severity and ignition frequency unaddressed. Lightning ignitions, any of which could burn a large...

2009, Photogrammetric Engineering and Remote Sensing (75) 831-843
This paper presents a hierarchical, multi-stage adaptive strategy for image classification. We iteratively apply various classification methods (e.g., decision trees, neural networks), identify regions of parametric and geographic space where accuracy is low, and in these regions, test and apply alternate methods repeating the process until the entire image is...
