An Egocentric Spatial Data Model For Intelligent Mobile Geographic Information Systems, Christopher E. Frank
An Egocentric Spatial Data Model For Intelligent Mobile Geographic Information Systems, Christopher E. Frank
Electronic Theses and Dissertations
Individuals in unknown locations, such as utility workers in the field, soldiers on a mission, or sightseeing tourists, share the need for an answer to two basic questions: "Where am I?" and "What is in front of me?Because such information is not readily available in foreign locations, aids in the form of paper maps or mobile GISs, which give individuals an all-inclusive view of the environment, are often used. This panoptic view may hinder the positioning and orienteering process, since people perceive their surroundings perspectively from their current position. In this thesis, I describe a novel framework that resolves this …
Perceptual Sketch Interpretation, Markus Wuersch
Perceptual Sketch Interpretation, Markus Wuersch
Electronic Theses and Dissertations
Sketching is a creative form of describing a spatial scene. People perceive such a scene in a straight forward way and build a mental model of the objects contained in a sketch. Whereas these objects might be regions, a sketch only contains lines and, therefore, developing automated sketch interpretation means outlining a rationale to grouping lines according to the objects they belong to. Automated sketch interpretation allows efficient processing of sketches. Labor intensive manual extraction could be brought to a minimum and, therefore, spatial data in form of sketches and spatial information extracted from sketches would be available more readily. …
Public Commons For Geospatial Data: A Conceptual Model, Chakravarthy Namindi Sharad
Public Commons For Geospatial Data: A Conceptual Model, Chakravarthy Namindi Sharad
Electronic Theses and Dissertations
A wide variety of spatial data collection efforts are ongoing throughout local, state and federal agencies, private firms and non-profit organizations. Each effort is established for a different purpose but organizations and individuals often collect and maintain the same or similar information. The United States federal government has undertaken many initiatives such as the National Spatial Data Infrastructure, the National Map and Geospatial One-Stop to reduce duplicative spatial data collection and promote the coordinated use, sharing, and dissemination of spatial data nationwide. A key premise in most of these initiatives is that no national government will be able to gather …
User Controlled Privacy Protection In Location-Based Services, Anuket Bhaduri
User Controlled Privacy Protection In Location-Based Services, Anuket Bhaduri
Electronic Theses and Dissertations
The rapid development of location-determining technologies has enabled tracking of people or objects more accurately than ever before and the volume and extent of tracking has increased dramatically over time. Within the broader domain of tracking technologies, location-based services (LBS) are a subset of capabilities that allow users to access information relative to their own physical location. However, the personal location information generated by such technologies is at risk of being misused or abused unless protection capabilities are built into the design of such systems. These concerns may ultimately prevent society from achieving the broad range of benefits that otherwise …
Spatial Aspects Of Metaphors For Information: Implications For Polycentric System Design, Paul Charles Schroeder
Spatial Aspects Of Metaphors For Information: Implications For Polycentric System Design, Paul Charles Schroeder
Electronic Theses and Dissertations
This dissertation presents three innovations that suggest an alternative approach to structuring information systems: a multidimensional heuristic workspace, a resonance metaphor for information, and a question-centered approach to structuring information relations. Motivated by the need for space to establish a question-centered learning environment, a heuristic workspace has been designed. Both the question-centered approach to information system design and the workspace have been conceived with the resonance metaphor in mind. This research stemmed from a set of questions aimed at learning how spatial concepts and related factors including geography may play a role in information sharing and public information access. In …
Remote Sensing Systems Optimization For Geobase Enhancement, Steve J. Paylor
Remote Sensing Systems Optimization For Geobase Enhancement, Steve J. Paylor
Theses and Dissertations
The U.S. Air Force is in the process of implementing GeoBase, a geographic information system (GIS), throughout its worldwide installations, Air Force GIS needs can be augmented by imagery from aerial and satellite platforms. Imagery has greatly improved over the past several years and provides high resolution coverage of features on earth. Various imagery types will significantly increase GeoBase usefulness in a range of mission requirements, Potential Air Force uses of imagery include identifying heat loss, environmental monitoring, command decision-making, and emergency response, The research develops a decision tool to determine the appropriate imagery for a given Air Force Application, …
Combining Dynamic Cartography And Temporal Gis To Visualize Industrial Development In Kitchener, Ontario, Canada, Shawn Mueller
Combining Dynamic Cartography And Temporal Gis To Visualize Industrial Development In Kitchener, Ontario, Canada, Shawn Mueller
Theses and Dissertations (Comprehensive)
This thesis uses dynamic cartography and temporal geographic information systems (GIS) to explore visualization of the industrial development of Kitchener, Ontario. The discussion centres on the nature of dealing with temporal data in geography. This project addresses this issue by constructing a temporal dataset that accounts for the historical location of industrial/manufacturing businesses in Kitchener. Based on this temporal data, animated visualizations are then constructed that show the cadence and distribution of industrial development in Kitchener. The visualization process used by this project makes use of the inherent temporality of GIS to plan and construct animated visualizations in a way …
Gis Modeling Of Desert Root Crop Maturation On The Mid-Columbia Plateau, Mary Michelle Phillips
Gis Modeling Of Desert Root Crop Maturation On The Mid-Columbia Plateau, Mary Michelle Phillips
All Master's Theses
The settlement patterns of the prehistoric inhabitants of the Columbia Plateau were choreographed to match the cadence of the seasons, with movements timed to efficiently utilize available resources. Desert roots, such as lomatium and bitterroot, provided a primary source of dietary nutrition, yet the ideal conditions for exploiting these plant resources coalesced for a very limited time in any one location. It was therefore necessary to possess an intimate knowledge of the plants' lifecycles in order to effectively plan gathering activities. In order to predict the growth patterns and maturation rates of these desert root crops, a GIS model was …
