Techniques For The Visualization Of Positional Geospatial Uncertainty, Brent A. Barré

University of New Orleans Theses and Dissertations

Geospatial data almost always contains some amount of uncertainty due to inaccuracies in its acquisition and transformation. While the data is commonly visualized (e.g. on digital maps), there are unanswered needs for visualizing uncertainty along with it. Most research on effectively doing this addresses uncertainty in data values at geospatial positions, e.g. water depth, human population, or land-cover classification. Uncertainty in the data’s geospatial positions themselves (positional uncertainty) has not been previously focused on in this regard. In this thesis, techniques were created for visualizing positional uncertainty using World Vector Shoreline as an example dataset. The techniques consist of a …

Uses And Perceptions Of The Neighborhood Open Space, Romain Cheynet

University of New Orleans Theses and Dissertations

This research investigates the uses and perceptions of the population of the East Carrollton Area in New Orleans so as to evaluate the possible outcomes of urban design intervention and policy changes. Using GIS, field notes, structured interviews and a population survey, this research evaluates how much the built environment influences the uses of the neighborhood open space. Subsequently, it evaluates how the neighborhood open space is perceived as a place as opposed to a transportation infrastructure.

Overall, the built environment affects the experience of the residents when they perform leisure activities in the neighborhood open space. Major deterrents to …
