Context-Specific Preference Learning Of One Dimensional Quantitative Geospatial Attributes Using A Neuro-Fuzzy Approach, Georgios Mountrakis
Context-Specific Preference Learning Of One Dimensional Quantitative Geospatial Attributes Using A Neuro-Fuzzy Approach, Georgios Mountrakis
Electronic Theses and Dissertations
Change detection is a topic of great importance for modern geospatial information systems. Digital aerial imagery provides an excellent medium to capture geospatial information. Rapidly evolving environments, and the availability of increasing amounts of diverse, multiresolutional imagery bring forward the need for frequent updates of these datasets. Analysis and query of spatial data using potentially outdated data may yield results that are sometimes invalid. Due to measurement errors (systematic, random) and incomplete knowledge of information (uncertainty) it is ambiguous if a change in a spatial dataset has really occurred. Therefore we need to develop reliable, fast, and automated procedures that …
A Data Model For Exploration Of Temporal Virtual Reality Geographic Information Systems, Jorge Alberto Prado De Campos
A Data Model For Exploration Of Temporal Virtual Reality Geographic Information Systems, Jorge Alberto Prado De Campos
Electronic Theses and Dissertations
Geographic information systems deal with the exploration, analysis, and presentation of geo-referenced data. Virtual reality is a type of human-computer interface that comes close to the way people perceive information in the real world. Thus, virtual reality environments become the natural paradigm for extending and enhancing the presentational and exploratory capability of GIs applications in both the spatial and temporal domains. The main motivation of this thesis is the lack of a framework that properly supports the exploration of geographic information in a multi-dimensional and multi-sensorial environment (i.e., temporal virtual reality geographic information systems). This thesis introduces a model for …
Investigation Of Geobase Implementation Issues: Case Study Of Information Resource Management, Mario L. Oliver
Investigation Of Geobase Implementation Issues: Case Study Of Information Resource Management, Mario L. Oliver
Theses and Dissertations
Billions of dollars have been wasted on failed information system (IS) projects over the last decade in the private and public sectors. More specifically, the tri-service environment of the U.S. military has not implemented a single successful geospatial IS (GIS). The lack of a service-wide insertion process for GIS was cited as the most significant cause for military GIS failures. GeoBase represents the USAF's most recent GIS implementation. The GeoBase program focuses on Information Resource Management (IRM) and cultural issues. The GeoBase Sustainment Model (GSM), anecdotally developed by GeoBase leadership to reflect implementation issues and the IRM practices of the …
