Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn
Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn
All-Inclusive List of Electronic Theses and Dissertations
Deer-vehicle accidents (DV As) are a problem in many areas. They cause millions of dollars in property damage, personal injury, and loss of life each year. This thesis examines whether DVAs in Vigo County, Indiana during the year 2000 were spatially autocorrelated; and whether DV As selected by deer habitat were spatially autocorrelated. Specifically using Moran's I to test for spatial autocorrelation this study determined if and to what degree spatial autocorrelation existed among these DVAs. A Moran's I value of .0023 shows that the accidents occurred randomly. These DV A data were then used to plot a map which …

This paper investigates the impact of fire on surface albedo and the associated radiative forcing over 56% of continental Australia encompassing the fire-prone northern tropical savanna. Fire-affected areas and albedos are derived for the 2003 fire season using daily Moderate Resolution Imaging Spectroradiometer (MODIS) surface reflectance data. Near-infrared and total shortwave albedos are observed to generally decrease after fire occurrence. Regionally, the total shortwave albedo drops by an average of 0.024, with increasing reductions as the dry season progresses and larger reductions in grasslands than woody savannas. These fire-induced albedo changes exert a positive forcing at the surface that increases …
