An Alternate Approach To Ecosystem Mapping: Fusing Orthophotography With Landsat Etm+ Data For A Object-Based Classification, South Eastern Arkansas., David Mcfee

Graduate Theses and Dissertations

Maintaining representative sampling of biologically rich and rare ecosystems has become an important means to preventing biodiversity loss. A limitation in indentifying and quantifying ecosystems is the cost of obtaining high resolution imagery necessary for a high resolution land cover assessment. This research shows how free, different resolution imagery (orthoimages and LANDSAT ETM+) could be combined to produce a hybrid dataset with enhanced spectral, spectral and temporal properties, and processed to obtain a object-based classification of land cover of bottomland and pine hardwood forest in south eastern Arkansas. Three classification techniques were evaluated: 1) a human derived, rule based method, …

Navigation And Accessibility For Persons With Disabilities: An Anthropological Study Using Gis On The University Of Arkansas Campus, Deborah Jean Raiees-Dana

Graduate Theses and Dissertations

The University of Arkansas was founded in 1871 on the top of a hill overlooking the Ozark Mountains, resulting in a campus that has steep slopes and numerous historical buildings that were not designed with ADA regulations in mind. This makes getting around campus especially difficult for students with limited mobility, and no campus maps exist that include handicapped accessibility features to help navigate the terrain and limited parking options. This study examines this issue using a holistic approach that explores cultural and technological factors to produce a map of the Historic Core District of campus.
