Accuracy Assessment Of Land Cover Maps Derived From Multiple Data Sources, Daniel Unger, Hillary Tribby, Hans Michael Williams, I-Kuai Hung Mar 2006

Accuracy Assessment Of Land Cover Maps Derived From Multiple Data Sources, Daniel Unger, Hillary Tribby, Hans Michael Williams, I-Kuai Hung

Faculty Publications

Maximum Likelihood (ML) and Artificial Neural Network (ANN) supervised classification methods were used to demarcate land cover types within IKONOS and Landsat ETM+ imagery. Three additional data sources were integrated into the classification process: Canopy Height Model (CHM), Digital Terrain Model (DTM) and Thermal data. Both the CHM and DTM were derived from multiple return small footprint LIDAR. Forty maps were created and assessed for overall map accuracy, user's accuracy, producer's accuracy, kappa statistic and Z statistic using classification schemes from U.S.G.S. 1976 levels 1 and 2 and T.G.l.C. 1999 levels 2 and 4. Results for overall accuracy of land …

Spatial Analysis Of Historic Cemeteries: Using High Spatial Resolution Imagery As A Visual Aid, Richard E. Brooks, Daniel Unger, I-Kuai Hung Jan 2006

Spatial Analysis Of Historic Cemeteries: Using High Spatial Resolution Imagery As A Visual Aid, Richard E. Brooks, Daniel Unger, I-Kuai Hung

Faculty Publications

Oak Grove Cemetery, located within the City of Nacogdoches in Nacogdoches County Texas, is one of the earliest cemeteries in the county dating to the early 1800’s. Several historic Texans are interred within this cemetery including Thomas J. Rusk and Charles S. Taylor who was the great-great-grandfather of current United States Senator Kay Bailey Hutchison. Due to a fire circa 1910 many of the records for the original section of the cemetery were lost. In the summer of 2006, the GPS coordinates of each grave marker within the cemetery were plotted on a backdrop of 6 inch spatial resolution multispectral …


Coherent Structures And Aeolian Saltation, Jean Taylor Ellis Jan 2006

Coherent Structures And Aeolian Saltation, Jean Taylor Ellis

Faculty Publications

Aeolian sand transport models, widely employed by coastal scientists and managers, assume temporal and spatial homogeneity within the saltation field. This research questions that assumption by demonstrating that the saltation field is event-driven, therefore indicating that the saltation field is not temporally steady. The findings from this research may explain a portion of the conclusions from previous studies that indicated inequalities between model-estimated and field-measured aeolian sand transport. The relationship between unsteadiness in a turbulent wind field and pulses in a sand transport field was investigated on a beach near Shoalhaven Heads, New South Wales, Australia. Microphone-based saltation sensors, “miniphones,” …


Topographies Of Home And Citizenship: Arab American Activists, Lynn A. Staeheli, Caroline R. Nagel Jan 2006

Topographies Of Home And Citizenship: Arab American Activists, Lynn A. Staeheli, Caroline R. Nagel

Faculty Publications

Home and citizenship carry contradictory and ambiguous meanings for immigrants as they negotiate lives ‘here’ and ‘there’. We use the concept of topography to analyze the ways in which activists in the Arab-American community draw connections between homes in the United States and in the Middle East. In intensive interviews, we ask activists about how their understanding of home influences their activism and positioning as citizens within the United States. Activists often bring to their work conceptualizations of home and citizenship that are open, and that connect home to broader forces operating at various scales and in more than one …
