For an Urban History of Milan, Italy: The Role of GIScience
… Italy, employing Geographic Information Science (GIScience). Using historical maps and ancillary data, the spatiality of historical events that interested the city is analyzed, interpreted and explained by means of new geospatial technologies used to both corroborate and at the same time confute …

Auto-tuned optimized parallel I/O for GIScience and spatial applications
… library specialized for spatial data analysis in GIScience, capable of treating different I/O patterns such as Row-Wise, Column-Wise and Block-Wise I/O. We then establish an auto-tuning framework for finding optimal parallel I/O configurations. This auto-tuning framework is based on genetic …

Exploring the utility of a GIScience approach to modeling invasive species: A case study of Ailanthus altissima
This thesis investigated the potential for integration of remotely sensed and GIS data into an agent-based modeling environment in order to model seed dispersal and subsequent establishment of windborne seeds. In order to explore the applicability of agent-based modeling to predicting seed …

A Critical Spatial Econometric Counter Analysis of the Impact of New Toxic Facilities on Local Wages
… challenged. Analysis is performed by applying GIScience and Spatial Econometric methods within a critical framework. A call is made to develop more broadly the practice of Counter Analysis, which is presented as an analogue of Counter-Mapping that repurposes Spatial Analytic methods for the …

Family Arrest and Separation During the Holocaust in Italy
… during the Holocaust in Italy from a GIScience and historical geographical perspective. Starting from a large GIS database of individual victims of the Holocaust in Italy, a methodology was devised to identify family groups from individuals' lists and to determine if and when families …

Thinking the Geoweb: Political economies, `neo'geographies, and spatial media
Critical GIS and GIScience face tremendous methodological and conceptual challenges at present as they grapple with the emergence and proliferation of a diverse range of new, Web-based geographical information technologies that cannot be defined or engaged in terms of conventional GIS. Together, …

Making Sense Out of Uncertainty in Geospatial Data
… explores uncertainty in spatial data, GIS and GIScience via three papers. The first paper introduces a framework for classifying and modeling error-bands in a GIS. Paper two tests GIS users' ability to estimate spatial confidence intervals and the third paper looks at the practical application …

Examining the neighborhood effect averaging problem (NEAP) in people’s exposure to mobility-dependent environmental factors: A spatiotemporal modeling approach
… To achieve the research goals, I employ advanced GIScience methods and individual-level activity-travel diary data of about 4000 participants living in Los Angeles, California. First, the results indicate that the NEAP exists when assessing individual exposures in the study area. Specifically, …
